http://www.unix.com – Hi guys, I appreciate any help in this regard, we have lost sensitive data in the company. One box with 2 disk mirrored and a 3ware controller handling 13 disks in a raidz2 pool. Suddenly the box restart and keeps "Reading ZFS config" for hours. Unplugging disk by disk we isolate the disk was causing the system not to be able to restar and we execute 'zpool clear -F' as suggested by 'zpool status' command. During hours of proccess we get a console error from the controller, and the system hangs, so we decide to change such disk, getting the pool from DEGRADED to FAULTED. After o (HowTos)
