tried the community version
Tried NexentaStor community version - I aspired to build a ZFS-based NAS for home, with snapshotting and all that good stuff that ZFS brings. But Sun/Oracle's abandonment of Open Solaris rattled my confidence and I gave up.
That and the thing almost worked. Documentation is at worst incorrect/outdated and non-existent at best. There wasn't enough critical mass in the forums/wiki's to be self-supporting.
I suspect the paid versions have to be better but would it kill them to write stuff down once in a while?
