...n tell. The pool contains 150 filesystems, including snapshots. It is an active server, and generally has several users writing to the disk at any one time.

Ok, so I''m planning on wiping my test pool that seems to have problems with non-spare disks being marked as spares, but I can''t destroy it: # zpool destroy -f zmir cannot iterate filesystems: I/O error Anyone know how I can nuke this for good? Jim This message posted from opensolaris.org

I''ve recently re-installed an X4500 running Nevada b109 and have been experiencing ZFS lock ups regularly (perhaps once every 2-3 days). The machine is a backup server and receives hourly ZFS snapshots from another thumper - as such, the amount of zfs activity tends to be reasonably high. After about 48 - 72 hours, the file system seems to lock up and I''m unable to do anything
