back to article Sysadmin wiped two servers, left the country to escape the shame

Grab a very small cake and a bunch of candles, dear readers, for today we mark the 10th edition of “Who, me?”, The Register’s confessional for IT pros who broke things badly. This week, meet “Graham” who “ended up as an authority on a fledging new product called SFT III from Novell. SFT stood for “system fault tolerance”. “ …

    “I have subsequently moved to Australia to try and put this behind me,” Graham concluded.

    A bit too far for a mere cockup and a definitely not far enough if those servers belonged to people you really need to run from.

    I had to maintain a few of those during the hungry 90-es on the other side of the wall and I prefer not to remember the details of that. Healthier that way. Less likely to find my remains 10m up in the air starting the car.

    Ohhh SFT III...I set that up for a company that used to make bricks for kilns.

    It was a real pig to get running - the hardware had to be absolutely identical, even down to the disk firmware and, if I recall correctly, geometry. Which was a problem when Compaq sent the same part number disks but from a different manufacturer.

    Anyway I still remember being asked to nip a spare fibre cable down, as they weren't far from where I lived.

    It was quite a thick, glass fibre. When I went to the stores to get it, the store man merrily bent it over itself to fit in a jiffy bag. I could literally hear it snapping each bend.

    "Oh well...we need another one now" :)

      Making bricks - how appropriate for SFTIII. Having inherited an SFTIII installation, I found that as long as you didn't want to change anything ever, it was fine, but in a dynamic environment, it was a ball and chain on change.

      Who remembers those "demonstrations" at the Networks show in Birmingham in the 90s, where Novell dropped anvils on one of a pair of running servers to show, er, gravity or something. That kind of 90s loadsamoney waste was one of the reasons I was turned off Netware and started heading towards this new NT thing, which turned out to be rather good, and cheaper too. Imagine that - MS cheaper, no doubt as Netware had to pay for demo anvils.

          I remember seeing the Compaq Destructive Testing Lab when I was a contractor back in Houston in the 90s. It seemed they would attempt to crush servers, then act surprised when the poor machine actually crushed. I really don't know how that was supposed to help the average buyer ... "Yes, but our servers can stand up to FOURTEEN thousand pounds of force!" sorry, mate, if there's 14,000 pounds force extra in your server room, there's a problem that most likely needs immediate attention.

        Mirror, mirror, off the wall...

        Ah yes, I remember! We ran a semi-critical development environment on one of these setups, way back. We never had the old 'anvil falling from the sky' incident on our site, but we did have some sort of nasty OS software corruption on one of the boxes that caused it to go TITSUP. Fortunately, we had the second box, which was instantly mirrored to duplicate the... no, wait, stop!!!

        The whole system was offline for about a week.

        Yes, back then mirrored servers was the sort of thing done by DEC at very high cost, so the SFT idea was a good try at a lower cost but did have that unfortunate requirement to be a very homogeneous environment. Then again, in my experience so did the higher end stuff as well, but the variability was lower in that high cost environment.

        I tried the SFT way once but decided it wasn't necessary in a file server environment as long as one kept sufficiently frequent backups. The file focused nature meant that large amounts of data weren't at risk. Novell servers weren't that often used for database hosting.

        Funnily enough we looked at Windows NT as an alternative F&P solution and concluded that it was absolute garbage compared to a Novell installation well through into the 2000's. Even had an MS "evangelist": tout its security advantages until one of my peers pointed out that the "high" security rating only applied when the NT server was running in an air-gapped environment and wasn't connected to any other system. If there were connections the rating changed to very poor.

        Biggest problem sticking with Novell through the late 1990's was the sabotage campaign the MS conducted as it used undocumented procedure calls and hidden features to disable Novell client connections on PC's. This wasn't revealed as an active campaign until much later, and at the time people tended to blame Novell, which was rather MS';s intent and did help (in my environment) promote the desire to change over to Windows server despite the inadequacies and heavy footprint of AD at the time.

          You didn't always need Microsoft's assistance to break the Netware client. Back in the early naughties and I was working for the NZ branch of a very large Japanese consumer electronics manufacturer. Who would regularly send out updates to their reporting software that would break the Netware client on Windows requiring a reinstall of the Netware client. On every single computer. I can only guess that it was pushing Japanese language DLL's or something similar.

          VMS clusters can be quite unhomogeneous, VAX8800 with Alpha DS10 and MicroVAXes, as long as they're running the same VMS version. Different CPU architectures require that the system disks be separate (you can have a common system for all the machines of the same arch), but data disks can be mirrored right across them. For disk mirroring you do want roughly identical sized disks, although they don't need to be exactly identical. Just that you want to start building the mirror set off the smallest.

    Incremental backups?

    I don't know the full story; but wouldn't taking a full backup before starting a major operation be prudent?

      Re: Incremental backups?

      But the company probably had an ISO 9001 certificated backup procedure of monthly full backups followed by daily incrementals with specioied policies of how the tapes get shuffled around the firesafe/sent off site/etc etc so taking a full backup would have been an exception to the policy and required far too much paperwork/management sign-off to contemplate.

        And of course you just wait for some minion to make an incremental back-up over the top of the full one, or to use the same tape for the full one each month and end up overwriting the historical archive once it gets too full.

        had an ISO 9001 certificated

        ISO 9001 only specifies that you have a process and follow that process in a documented fashion. It doesn't specify that the process has to be any good or have any value.

        So a process that says "we do nothing about backups" is a valid ISO 9001 process as long as you can proved in documentation that you did nothing.

        Of course, that would then fail any ISO 27001 certification but that's a whole different can of Annelids.

        I've worked at places that do both ISO schemes. Which is why I'm so cynical about it..

          "ISO 9001 only specifies that you have a process and follow that process in a documented fashion. It doesn't specify that the process has to be any good or have any value."

          That was one of the objections I had about ISO 9001. It was supposed to be a quality management standard but providing the "quality" was repeatable it didn't matter how bad it was. I kept calling the mediocrity management system.

          We introduced it after TQM. It was supposed to bea step up from that. As TQM had a mantra of Get it right First Time Every Time I wanted to know how, if we were already doing that, it could be a step up.

            TQM brings back memories. The government agency I worked for pretended to adopt it when a political appointee who was mad about it forced all the agencies under his control to do it. The agency had been zig-zagging back and forth between management fads for a while. A lower level manager I knew wrote a proposal that the acronym be changed to CQM (C=first letter of agency's name), and remain CQM regardless of future zigs and zags so it looked like we were maintaining steady progress forward. He did it as a joke - he got an award for it.

          In my days at an ISO manufacturer, my standard line was that:

          ISO 9000 = "we have processes"

          ISO 9001 = "we have processes, and we wrote them down"

          ISO 9002 = "we have processes, we wrote them down, and we follow them"

          We ended up doing ISO 13485 at one point. I couldn't even come up with a cute joke about that.

          I've heard that the latest 9001 is focused more on risk management than specific processes. Sounds good in theory, but I have a feeling that most auditors just won't get it.

        We had some databases which were prone to getting corrupted due to what was eventually traced to a hardware issue. The recovery process was to rebuild by restoring the previous nighty backup and rolling forward using the transaction logs. One one such occasion, I had cleared the wrong directory as part of the reset, losing some configuration files which would prevent restarting the database. No idea what made me think of the solution, which was to connect to one of the other remote sites (each had identical server builds), copy over the zapped files and carry on...

    On the day of the local gardening competition his grandfather watched as the boy revealed each plant. After the third stunted one his grandfather shook his head and went home. The next one was a giant. The boy took it to the competition tent - which was deserted - and managed to fit it into the display by removing its leaves.

    After the judging - the boy and his grandfather looked at the results. The grandfather admired the cauliflower which was now sporting a "2nd" rosette. A judge remarked that if it had had its leaves it would have been the winner.

    The grandfather put his spectacles on and picked up the plant's identification card saying admiringly "Now let's see who this expert is".

        Re: Biggest point - glossed over.

        Once again long time ago, using an odd OS called Magix (I think, could have been Magic), was a Pick-like PC oriented OS for database development. Had a number of sites with their own server running a production and sales database and each system had a tape backup unit with a well established backup process. You know the sort of thing, 2 x Monday, Tuesday etc, 5 x Fridays, all rotated and stored in a separate part of the site - and even tested so that we were reasonably certain that the backup and restore process worked.

        So one site had a serious hardware fault that brought the server down, so we replaced it. Loaded a fresh OS copy, configured everything and then fetched the latest tape and set about restoring the Data. Up popped a message - "Please put in Tape 1". Puzzled we tried again, and then tried the rest of the tape series, all with the same message. So we summoned the operator and asked about this. His response was that a few weeks back the back process had started to pop the tape out and ask for a second tape to be inserted - so he just pushed the same tape back in ! Never thought to tell anyone about this. Disaster loomed, as we'd tried every day and every Friday tape we knew about. Then by sheer luck I saw another atpe sitting over the other side of the office on a shelf and asked what it was - turned out that two days before the user had wondered about the two tape thing and had actually but in a new tape on that day and that was the magical "Tape 1" from two days back. And hallelujah, it was exactly that, put that in and then the two day ago tape 2, and voila, a working system with only 2 days of update data required.

        Quite why the operator said nothing at first, and then did try a second tape at that crucial point - and not mention it earlier - we never did find out. We just thanked our lucky stars and did a runner to the pub for something to calm the nerves.

        Next day a memo goes out saying that if the system asked for a second tape: first use a new tape (and label it) and second, tell IT Support !

      Just to add that back in the day with mainframes and exchangeable discs we always (on full backup day once a week) took the full backup to tape, removed the discs, put in fresh disc packs and restored to them.

      We always had a proven set of backup tapes plus the discs from a running system.

      Three sets of tapes as well.

    SFTIII was great

    It mirrored servers perfectly, down to the smallest of faults. One server developed a fault? You could be sure the other would follow as soon as the mirror caught up.

    Apart from that the majority of SFTIII installations I encountered suffered from the hardware being Netware compliant but not SFTIII compliant, so it didn't work correctly.

    A long time ago I was making totally legal backups of Amiga games. Ahem.

    Yeah, ok, so I was pirating some games, and to do so, a friend had lent me his copy of White Lightning, which was reputed to be able to copy pretty much anything, and fast. Not having much in the way of pocket money, even new blank discs were pretty pricey, so I'd not even bothered to make a copy of White Lightning, and so I was using my freind's diskette to copy various games.

    You can probably guess what happened next, somehow I mixed up which disc was in which drive, and wrote over my friend's copy program. At the time I remember trying to blame it on him leaving the copy protect tab open on the disc. Sorry Tim.

    Since then I've learnt my lesson and only got 'Source' and 'Destination' the wrong way round about four or five times since. Maybe six. Or seven.

      Started learning my more serious computing with a Sinclair QL (when they were being sold cheap at Dixons). The first lesson with a QL was backup everything because the microdrives were finicky as hell!

      I ended up having 3 or more copies of everything I was using. Still paranoid even now.

      I made a slightly more serious mistake when my 20Mb Amigs HDD filled and I bought a new one. My RocTec HDD didn't have a second IDE power cable or splitter so to copy from one to the other, I plopped the two drives on top of each other so the connectors were aligned and jury rigged a power cable by putting the loose ends of a spare 4 pin connector into the same positions of the old drive.

      Sadly, somehow the pins were in the other order on the new drive, and I toasted my old drive.

      Fortunately I'd backup up most of my work onto floppies, but it was an expensive lesson, particularly back in 1992 odd.

    SFTIII

    I remember having this in my client's site in the mid 90's. It worked too well, when one server went down it switched seamlessly over to the secondary... so seamlessly no-one noticed the primary had failed, until two months later when the secondary also failed.

    And then we had to work out which one had failed first so that when we bought them back up again, they synched the right way. It was a 50/50 chance, so of course we got it wrong.

      Had a couple of instances at a council. First one had one physical server die (hardware failure) and it ran better with one server than it ever did with two.

      Second one was just being installed, using that new-fangled Netware 4 SFT, and it nicely decided to get involved in a reboot-crash cycle, with both server alternately ABENDing, restarting, joining the SFT III cluster-thingy just before the second server crashed and repeated the cycle. Users didn't see much of a problem, but it was a sod to fix.

    Another interesting one, upgrading an IBM Power server with new firmware, and it failed, borking the machine. Turned out that the check processor that solely existed to check that things were working OK, wasn't working so the machine failed because it couldn't check that it was running OK !

    There must be a way to start without the check processor so we could restart the firmware upgrade process. IBM tech discovered that process at 4:30 am (started at 11 pm) on page 400 or something like that in Appendix XII of the manual. After that it took a mere 2 minutes to boot, reload the firmware, and restart and all was go.

    But a tension filled 5 1/2 wait in between.

    You got to know when to run

    Just out of high school I worked briefly at a steel mill in the electrical shop. They had these "little" 1 to 10MW aux generators that ran on gas to handle peak loads. Part of my job was to synch these to mains bus before closing breakers. I failed, and one of the synchronous machines ripped off it's mounts and left the shop. For the most part it went dark. I quit real fast and did a GTFO before the metal workers - paid by the piece - arrived to perhaps literally tear me from limb to limb

    Thought for a moment it was the SFT II failure I encountered

    (which I mentioned previously) where the customer *didn't* have a backup, and an engineer had to sit on site for a week recreating the system from printouts..

    There was also the customer who really knew their stuff, and had asked their supplier for a particular HP tape drive. The tape drive arrived, and Did Not Work. Looking at it the customer noted that this wasn't an HP tape drive 'that's ok' said the supplier 'it's actually exactly the same drive, just not HP branded'. 'No', said the customer-with-clue, 'the HP drive has a special chip which enables it to work in this server, and your compatible version does not. Please ship the genuine part'

    Self harmed

    What I did in the 80s, was very similar. Had spent a good few man months working on a very detailed fully illustrated User Guide for what became our well reviewed well loved but commercially failed because it was TBEX (Too Bloody Expensive) during a crashing late 1980s economy Classic BiT BOPPER Audio Reactive Video Entertainment System.

    One day, I fired up the PC or whatever it was I was using to write the user guide on to do a backup. This involved inserting the 3 or 3.5" floppy disk into the machine's drive and copying the Word file ontop of the backup file. Simples!

    Errr...

    I dragged the user guide file onto the backup floppy. Grrdd grrdd grrdd grrddd etc. Done. (I recall that's the noise they made back then.)

    Later, when I went to open up the working user guide to wrap it up prior to launch, the Word file was empty, just a few lines of text.

    As one does during such crisis, I tried to understand what was going on. Flashes of my life and hard work went past as I tried to mentally deny I had lost months of effort. A corrupt file, virus etc?

    I then got the backup out, it was the same as the working file!

    On my PC, the windows I opened up were identical, as was (of course) the name of the file inside.

    I had dragged the WRONG file from the WRONG window, and overwritten my working file with a backup from months ago, that was in fact blank except for a few seconds of typing to open up the new Word file. I had for whatever idiotic reason, probably to do with time passing quickly and being busy, procrastinated on making full on periodical backups. I had lost everything, including the diagrams I had painstakingly drawn.

    I had to re do the whole user guide by copying from hard copy I had made a few weeks earlier of an earlier version, although I stopped about 75% way through when it became apparent the product itself was doomed due to the economic crash of the late 80s/1990.

    The upside is we went on to develop a way cheaper compact version based on the Atari Falcon, and it's user guide was published both in print - AND online, one of the first user guides ever published online. Here you go, it's still there in lovely 1918 style html...

    http://www.tecterran.com/svbb/userguide/

    (For the record, people are still using this machine today for the retro visuals.)

    I learned a few lessons, that are less relevant today in a world of online publishing and dynamic cloud backups/syncing etc: a) Don't procrastinate in backing up stuff. b) Name your folders/windows differently!

    (I have never made such an error since.)

    In a way, what happened was probably a diving entity telling me I was wasting my time anyway, being the product was doomed.

    One from this weeked

    Migrating a customer from Windows XP/Outlook Express to Linux/Thunderbird. I'm still a bit hazy on the details, but it seems to be the difference between POP3 & IMAP.

    Imported the Outlook files into Thunderbird just fine and got Thunderbird talking to the ISPs mail server. Then the Good Idea Fairy suggested moving the migrated Outlook Inbox contents into the "real" Thunderbird Inbox. Great idea G.I.F., the customer will be happy everything is organised the same! But it seems that with IMAP, those emails are no longer on the server, so it duly synched the Thunderbird Inbox to remove all the "deleted" emails.

    Luckily the "customer" is my Mum, so I didn't get sacked. I just have to redo the import again.

    water, water, everywhere!

    decades ago I had an "in between" job as a building maintenance guy, working graveyard shift. One morning I went to turn on the A/C unit, but when I started the cooling tower pump, someone had shut the valve on the inlet of the A/C unit [only one guy ever did that]. It broke several 12" diameter PVC pipes running around the building, dumping tons of water into the parking garage. Yeah, the switch for the pumps was on the opposite side of the building from the A/C unit with the valve. I didn't get fired, though. But the A/C was down for several days [fortunately weather wasn't bad, and regular ventilation was sufficient] while the pipes were all re-done. With double-thickness pipe so it wouldn't happen again.

    Break a mirror? 7 y bad luck?

    I remember one of my first IT jobs where I supported POS systems. (in both senses of the acronym) Discovering early into the job that there were tape drives but only a few, filthy, incomplete backup tape sets, and no meaningful backups being done, I pushed the CIO to let me buy backup tape sets for all locations. Over $6K worth of tapes were bought. Subsequently I had some system failures and discovered that even with new tapes and perfectly working drives, I could only recover data about 1 in 5 times. (and this was when the closing store manager remembered to type "backup" at the login prompt before leaving)

    Add to that the daily backup process also mirrored the primary drive to the inert secondary (that was only used when the primary failed) in the wee hours of the morning. It would cheerfully mirror a failing, corrupted drive, and wipe out the last night's perfectly good backup on the secondary. To change the drive involved swapping drives and setting jumpers, then relicensing the software, which was tied to the drive's serial number. I drove 100 miles through a blizzard at least once to perform this asinine, 15-minute process.

    Mirror C: to X: first

    HDDs have never been that expensive that a server couldn't have several.

    1. jake Silver badge

      Re: Mirror C: to X: first

      Oh, I dunno. In 1986 my Sun server had a bottomless pit of a drive for user space. It was a 300 megabyte CDC Wren IV SCSI drive. It cost US$14,000 ... in 1986 dollars. (The "user" was a database archiving network statistics, if anybody's wondering.)

      Re: Mirror C: to X: first

      That assumes you can sensibly attach extra drives to a server, which isn't a given. Modern servers all have fast USB, historically you'd better hope there's external SCSI, spare drive bays, or similar.

        Re: Mirror C: to X: first

        "historically you'd better hope there's external SCSI, spare drive bays, or similar."

        My first server was a 100MHz P1 bought from university surplus for $10, in 2000. A Compaq with all kinds of weird custom parts inside (memory and processor on a riser card!), and the boot disk was a SCSI hard drive too small for practical use. So we added a second drive to an available IDE port. No extra drive bays - no problem, just zip-tied it to the existing drive bays. Ran like that for 5+ years, never had any problems with it. (Eventually replaced with a P3, which I am currently in the process of replacing. It's amazing how low-powered a small web/mail/file server can be.)

          Re: Mirror C: to X: first

          Sometimes you're lucky, but if the port is on a SAS/SCSI backplane IDE/SATA isn't an option.

          I recently copied VMs from one ESXi server to another, and initially thought I'd re-use the sole SATA connection intended for optical drives to directly copy between disks. It turned out that whilst there is an SATA connection, there is no SATA power feed or way to extract power from the custom redundant PSUs.

          Resorted to an external USB to SATA dock, which despite the fact previous versions of ESXi had fought tooth and nail when using USB storage, ESXi 6.5 was almost straightforward (once the USB service had been stopped, and various obscure commands run to identify the long GUID/lun identifier for the external disk and mount it)

    I was on the other side of planet earth all on my own, no-one to call when things got ugly. I was doing some remote work on a server at the country I was in. For a change, I thought I would have a go at using Windows 3.1 Winfile instead of DOS Norton Commander, but over the 14.4k modem the screen updates were really-really slow. "Oops" I clicked delete and then OK for it to delete all files on the OS/2 server. It was like a slow motion train wreck, nothing I could do, it slowly deleted everything in front of my eyes. The server I had deleted all the files from was core to the data communication system; all other servers of the data communication system started up from it. Complicated stuff with many configuration files that were being regularly updated whist debugging the new unreliable system, no regular tape backups; just the odd occasional one. The system kept running...phew! All I had to do now was book a flight to the other end of the country the following day. I had to get there before the next system crash, as crashes happened most days being a new system. Attempt to restore from backup, if complete enough, if good enough, if current enough to restore the folders, configuration files, then a very brave attempt of a complete system restart. Sphincter was like a goldfish mouth for 24 hours... got it going! If I hadn't, I don't know what I would have done.

    SFT wasnt so bad

    It was clever stuff - Fault Tolerance all done in SW on old (generic) kit with Intel single CPU speeds measured in the range of maybe 25-70MHz. So it was essential for the 2 machines to be identical if they were to operate in lock-step with each other - there simply weren't enough spare CPU cycles to deal with Hardware Abstractions and translations.

    Fault Tolerance (more or less) went away for a loooong time on generic intel kit until vmWare came along and virtualised everything but with the benefit of CPUs running at 50x the clock speed and multiple cores.

    I remember SFT at a Novell marketing session. The company I worked at only had a single server. It had failed hard drive twice in my time there, both on a Friday. The first time our vendor met their SLA with a replacement drive, but not with a restore by a Netware expert. I being a fresh minted CS grad with only 4 months Netware experience had to pull a weekend miracle to have it reinstalled and restored for Monday morning. The second time I had a bit more experience and was restoring from my redesigned backup system. I had fired the vendor for their dropping of the ball multiple times. I had ordered a new drive with overnight shipping via UPS. It was coming through California which had a major earthquake earlier that week. It arrived Sunday morning instead of Saturday morning. I was still able to have a working fully restored system by Monday morning. I also had UPS regional manager in my office over the lack of cooperation on their part to get the shipment there in spite of it being at the local UPS warehouse by Saturday afternoon. In both instances, I tested restores regularly prior to the event. My redesign was due to "lessons learned" from the first event. That redesign and my greater experience allowed me to to the same task in half the time (actually less). "Lessons learned" from the second event allowed me to redesign yet again with the goal to achieve an overnight complete system restoration given working hardware to which to restore. Never had to actually do one, but I simulated it multiple times to test the design, earlier tests failed, fix and redo.

    It replicated. What more do you want? :)

    I once had a similar thing happen when I added a new server to an existing DFS Replication group on Windows Server (two words that I've always said don't sit comfortably together). DFS-R very quickly and efficiently replicated the nice, capacious new storage volume to the other servers. (Hey, I could save some money on disks! No need to buy several new ones when we run out of space: just buy one and replicate it! Why didn't I think of that before? :-P )

    Thankfully, the data on that particular replication set was not mission-critical (it was mostly multimedia content) so it was merely inconvenient for the day or so it took to restore from the previous night's backup and re-replicate to the group.

    Since then, I've always pre-seeded new servers using Robocopy. DFS-R still insists on replicating the whole lot in one direction or the other (exactly which way seems to be totally random) when the server joins the group, causing massive fragmentation (this is NTFS, after all, where writing a 1MB file to a freshly-formatted 1TB disk will probably result in at least 60 fragments), but at least the losses are, at worst, limited to any changes saved to an existing server since the files were copied over to the new machine.

    I should have done this anyway the first time, just as I would have with NTFRS, but DFS-R was shiny and new and supposedly much more reliable (my a**e - there's a reason I held off migrating SYSVOL from NTFRS to DFS-R until Server 2012R2 migration forced my hand) and I thought it would be kind of cool to be able to just "set it and forget it" and watch it sort itself out without me having to lift a finger. Why did we bother upgrading to Server 2003R2 if not for the greater ease of administration? (Of course I'd also forgotten that, even if replication had gone the right way, the new server would immediately start advertising itself as a good place for the clients to find their content, despite most of it not yet having been copied over.)
