I don't know of any zfs features that aren't supported by Linux and zfs on linux. So this shouldn't be an issue. You may have to do some things with zfs from the command line on OMV since the plugin doesn't support everything zfs can do.
Thanks ryecoaaron -
Anyone else out there attempted a straight zpool import from FreeNAS into OMV ? - please?
Was thinking about using Debian for appliance OS (just because I am more familiar )
Reason for my caution presently.
The Zpool is currently configured at FreeNAS Version 10.2
Attempting to export the ZPOOL for backup sake seems to invoke more crazy than helpful.
"zpool export POOL" command suite in FreeNAS 11 has been jarred around with - the CLI version is now borking because there are services requiring it (including after shutting down all iocage jails and bhyve VMs)
- they are now forcing a key to be supplied. I fear doing this will create a massive headache for the OMV to import it.
even "zpool export -f POOL" failed as "Files Depend" on the pool - even the attempt to export this caused the FreeNAS Gui lose sight of the pool completely even though zpool status still said all okay (cache no doubt)
So bottom line
Is it "safe" to
1) cleanly shut down the NAS (without a zpool export)
2) start the NAS - install new OS (as I say Debian preferred)
3) install OMV
4) Import the FreeNAS 10 created pool straight into OMV
Am I likely to hit immeasurable road blocks and diversions - forcing me to need to create the pool from scratch?
Any other advice or others woes poured here would help me think about fitting my seatbelt ...
Thanks again and in advance ...
