[OpenIndiana-discuss] iSCSI volume and ZFS

[CJ Keist]

Yes, that would be the case. I'm looking at EMC iSCSI storage unit. So 
it's pretty much the same case that I have with our current OI system 
using Raid controller to present one single volume to create a ZFS file 
system on correct? There is the potential of loosing the entire ZFS file 
system if anything got corrupted during data transfers.
