Ok, this is not a OpenSolaris question, but it is a Solaris and ZFS question. I have a pool with three mirrored vdevs. I just got an error message from FMD that read failed from one on the disks,(c1t6d0). All with instructions on how to handle the problem and replace the devices, so far everything is good. But the zpool still thinks everything is fine. Shouldn''t zpool also show errors in this state? This was run on S10U4 with 127127-11. # zpool status -x all pools are healthy # zpool status pool: storage state: ONLINE scrub: scrub completed with 0 errors on Sun Jun 29 23:16:34 2008 config: NAME
