Normally you need to "zpool clear zfsPool", and rerun zpool scrub. If you see these numbers growing again, it's likely that there are some other problems with your hardware. The recommended configuration is to use ZFS to manage disks, or at least split your RAID volumes into smaller ones by the way, since otherwise the volume is seen as a "single disk" to ZFS, making it impossible to repair data errors unless you add additional redundancy (zfs set copies=3D2, etc). > > thanks, > ron. > > > > phoenix# zpool status -v zfsPool > pool: zfsPool > state: ONLINE > status: One or more devices has experienced an error resulting in data > corruption.
