It looks like the answer is no. [EMAIL PROTECTED] sudo sndradm -e localhost /dev/rramdisk/avstest1 /dev/zvol/rdsk/SYS0/bitmap1 \wintermute /dev/zvol/dsk/SYS0/avstest2 /dev/zvol/rdsk/SYS0/bitmap2 ip async Enable Remote Mirror? (Y/N) [N]: y sndradm: Error: both localhost and wintermute are local In order to use AVS, it looks like you'd have to replicate between two (or more) "ZIL Boxes". Not the worst thing in the world to have to do, but it certainly complicates things. Also, you don't get that super fast RAM->Disk sync anymore as you now have to traverse an IP network to get there. Still might be an acceptable way to achieve the goals we are looking at here. I guess at this point falling back to 'zfs send' run in a continuous loop might be an alternative. -brian -- "Coding in C is like sending a 3 year old to do groceries.
