Hi All, We are currently a hardware issue with our zfs file server hence the file system is unusable. We are planning to move it to a different system. The setup on the file server when it was running was bash-3.00# zpool status pool: store1 state: ONLINE scrub: none requested config: NAME STATE READ WRITE CKSUM backup ONLINE 0 0 0 c1t2d1 ONLINE 0 0 0 c1t2d2 ONLINE 0 0 0 c1t2d3 ONLINE 0 0 0 c1t2d4 ONLINE 0 0 0 c1t2d5 ONLINE 0 0 0 errors: No known data errors pool: store2 state: ONLINE status: One or more devices has experienced an unrecoverable error. An attempt was made to correct the error. Applications are unaffected. action: Determine if the device needs to be replaced, and clear the errors using 'zpool clear' or replace the device with 'zpool replace'. see: http://www.sun.com/msg/ZFS-8000-9P scrub: none requested config: NAME STATE READ WRITE CKSUM store ONLINE 0 0 1 c1t3d0 ONLINE 0 0 0 c1t3d1 ONLINE 0 0 0 c1t3d2 ONLINE 0 0 1 c1t3d3 ONLINE 0 0 0 c1t3d4 ONLINE 0 0 0 errors: No known data errors The store1 was a external raid device with slice configured to boot the system+swap and the remaining disk space configured for use with zfs. The store2 was a similar external raid device which had all slices configured for use for zfs. Since both are scsi raid devices, we are thinking of booting up the former using a different SUN Box. Are there some precautions to be taken to avoid any data loss? Thanks, --W |
Just make sure the external storage is not connected to both hosts at the same time.
Once you connect it to another host simply import both pools with -f (as pool wasn't cleanly exported I guess).
Please also notice that you've encountered one uncorrectable error in store2 pool.
Well, actually it looks like it was corrected judging from the message.
IIRC it's a known bug (should have been already corrected) - metadata cksum error propagates to top level vdev unnecessarily.
