Hi all,

toying with KVM. My development NAS has got only a very small SSD pool. Is it possible to mount a block device shared by my main NAS like I would with ESXI for example?

Thanks,
Patrick

So you would use iSCSI client and the create the ZFS pool using iSCSI LUNs?

It a planned future, but not in the current middleware and webUI.

It might work as a manual CLI configuration...

Yes, but come to think of it ... ZFS on a ZVOL via iSCSI is probably just as good as tunneling TCP in TCP ...

It will work OK..... having a local slog and L2ARC will help it perform. I would just do a ZFS stripe and assume the real TrueNAS is doing all the data protection. Most applications are filesystems on iSCSI LUNs, and ZFS is friendlier that most with larger write I/Os.
