That was the only solution that worked reasonably well.
We had some 'issues' with multiple hosts accessing the same nfs
'datastore' (vmware) which was just a single zfs filesystem.
Hosts would work fine for months on end, and then one would kinda crap
itself and only a reboot would fix it, losing all ~15 vms it was
And yes, we had ssd's for ZIL and L2ARC.
