Hi All, We have come across a problem at a client where ZFS brought the system down with a write error on a EMC device due to mirroring done at the EMC level and not ZFS, Client is total EMC committed and not too happy to use the ZFS for oring/RAID-Z. I have seen the notes below about the ZFS and SAN attached devices and understand the ZFS behaviour.
Can someone help me with the following Questions: Is this the way ZFS will work in the future ? is there going to be any compromise to allow SAN Raid and ZFS to do the rest. If so when and if possible details of it ? Many Thanks Rgds Roshan ZFS work with SAN-attached devices? > > Yes, ZFS works with either direct-attached devices or SAN-attached > devices.
