Don't know if this can be safely done on a large set, with a normal PC using a simple zpool mirror I'm hacking this doing: # zpool status tank pool: tank state: ONLINE scrub: none requested config: NAME STATE READ WRITE CKSUM tank ONLINE 0 0 0 mirror ONLINE 0 0 0 ad0p2 ONLINE 0 0 0 ad8p2 ONLINE 0 0 0 errors: No known data errors # zpool detach tank ad0p2 # glabel label disk01 /dev/ad0p2 # zpool attach tank ad8p2 label/disk01 # zpool status tank pool: tank state: ONLINE status: One or more devices is currently being resilvered. The pool will continue to function, possibly in a degraded state. action: Wait for the resilver to complete. scrub: resilver in progress for 0h6m, 17.06% done, 0h29m to go config: NAME STATE READ WRITE CKSUM tank ONLINE 0 0 0 mirror ONLINE 0 0 0 ad8p2 ONLINE 0 0 0 60.7M resilvered label/disk01 ONLINE 0 0 0 10.4G resilvered errors: No known data errors After the resilver I'll just go ahead with the other disk. It's working flawlessly for now. with a simple 2 disk setup this is quite easy, it can get tricky with complex designs(f.e. zraid2, hot spares, cache and log devices and so on...). If you have a complex design better make a detailed plan, before shooting your own foot. -- Guido Falsi <mad_at_madpilot.net>Received on Wed Jul 15 2009 - 07:05:09 UTC
