Hi, I''ve got a 10-disk raidz2 zpool with a dead drive (it''s actually been physically removed from the server pending replacement). This is how it looks: # zpool status space pool: space state: DEGRADED status: One or more devices could not be used because the label is missing or invalid. Sufficient replicas exist for the pool to continue functioning in a degraded state. action: Replace the device using ''zpool replace''. see: http://www.sun.com/msg/ZFS-8000-4J scrub: resilver completed after 0h0m with 0 errors on Tue Apr 1 15:08:29 2008 config: NAME STATE READ WRITE CKSUM space DEGRADED 0 0 0 raidz2 DEGRADED 0 0 0 c2t2d0 ONLINE 0 0 0 c2t3d0 ONLINE 0 0 0 c0t0d0 ONLINE 0 0 0 c0t1d0 ONLINE 0 0 0 c0t2d0 ONLINE 0 0 0 17557252296421049869 FAULTED 0 0 0 was /dev/dsk/c2t3d0s0 c0t4d0 ONLINE 0 0 0 c0t5d0 ONLINE 0 0 0 c0t6d0 ONLINE 0 0 0 c0t7d0 ONLINE 0 0 0 errors: No known data errors When I try and run a scrub it seems that a resilver is run instead of a scrub, and the resilver finishes almost immediately (as you can see from the "scrub: " line above. Is this normal behaviour? Or is something somewhat crook with my zpool? What''s going on with that long disk name (formerly c2t3d0s0) ? When I replace the failed disk (in the same port) will it be added to the array automatically, or will I have to add it manually (zpool replace) ? Thanks, R.
