Hello, I have a 4drive zfs pool with raidz on FBSD 8 and I accidentally tripped and yanked the sata wires off 2 drives while it was running. I immediately shutdown the server, fixed the wiring and re-started the server. Incredibly I ran zpool status and zpool scrub and only 8 files were damaged. I removed them and recovered from backup. I cleared the errors on the pool but I keep getting errors on the 4 drives. I am by no means a ZFS expert so all I have tried is: - zpool status - zpool scrub - dlete and restore files - zpool scrub - zpool clear Everything Ok and then I get ZFS-80008A again :-( My questions: 1) Would damage to the 2 disks cause damae on the other 2? 2) Is there a utility in FBSD to check the physical drive itself and mark any bad sectors as such? 3) Can all this be doen directly from ZFS commands, etc? Fortunatelly my FBSD system lives in a start-up IDE drive so I can un-mount the pool and run any utilities over the drives. Thanks in advance for any help! Alex
