Hi Luke, That's really strange. We did the exact same thing moving between two hosts (export/import) and it took maybe 10 secs. How big is your zpool?

Doug, I should have posted the reason behind this posting. I have 2 v280's in a clustered environment and I am going to attempt to failover (migrate) the zpool between the machines. I tried the following two configurations: 1. I used ZFS with STMS(mpxio) enabled. I then exported a zpool and imported it onto another machine. The second machine took 6 minutes to import the zpool. (Maybe I am configuring something wrong??) Do you use exports/imports?? 2. In a second configuration I disabled STMS(mpxio) and exported a zpool and imported it onto the other machine again. The second machine then only took 50 seconds to import the zpool. When dealing with clusters, we have a 5 minute failover requirement on the entire cluster to move. Therefore, it would be ideal to not have STMS(mpxio) enabled on the machines. Luke Schwab --- "Jason J. W.
