Hi,

a couple of days we had an issue with one of our FC switches which led to a switch restart. Due to this issue the zpool vdevs had been disconnected from the Solaris 11 host, which had to be restarted to get things running again.


Now, when I imported the zpools for this host, at the first glance, everything looked good: zpool list didn't show any issues, but zpool status did. It claims some data corruption and I seem to cannot get rid of if.

This is what zpool status says about this zpool:

zpool status -v VSM_POOL_tr1204631_32
  pool: VSM_POOL_tr1204631_32
 state: ONLINE
status: One or more devices has experienced an error resulting in data
        corruption.  Applications may be affected.
action: Restore the file in question if possible. Otherwise restore the
        entire pool from backup.

errors: Permanent errors have been detected in the following files:

        /VSM_POOL_tr1204631_32/FCE-Test/
        VSM_POOL_tr1204631_32/VSM_POOL_01:<0x0>


Now, /VSM_POOL_tr1204631_32/FCE-Test/ is the mount point of a zfs volume on that zpool and I can't find anything problematic with the zfs volume. Since I don't need that zfs volume anymore, I could easily remove it. The second error, however, disturbs me - it doesn't seem to point to a file or directory.

Thanks,
budy
