[zfs-discuss] RAID-Z2 won't come online after replacing failed disk
I replaced a bad disk in a RAID-Z2 pool, and now the pool won't come online. Status shows nothing helpful at all. I don't understand why this is, which I should be able to lose 2 drives, and I only replaced one! # zpool status -v pool pool: pool state: UNAVAIL scrub: none requested config: NAMESTATE READ WRITE CKSUM poolUNAVAIL 0 0 0 insufficient replicas raidz2UNAVAIL 0 0 0 corrupted data c2t0d0 ONLINE 0 0 0 c2t1d0 ONLINE 0 0 0 c2t2d0 ONLINE 0 0 0 c2t3d0 ONLINE 0 0 0 c3t0d0 ONLINE 0 0 0 c3t1d0 ONLINE 0 0 0 c3t2d0 ONLINE 0 0 0 c3t3d0 ONLINE 0 0 0 c4t0d0 ONLINE 0 0 0 c4t1d0 ONLINE 0 0 0 c4t2d0 ONLINE 0 0 0 c4t3d0 ONLINE 0 0 0 -- This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

Tim: I couldn't do a zpool scrub, since the pool was marked as UNAVAIL. Believe me, I tried :) Bob: Ya, I realized that after I clicked send. My brain was a little frazzled, so I completely overlooked it.

Re: [zfs-discuss] RAID-Z2 won't come online after replacing failed disk
Dustin, You didn't describe the process that you used to replace the disk so its difficult to commment on what happened. In general, you physically replace the disk and then let ZFS know that the disk is replaced, like this: # zpool replace pool-name device-name This process is described here: http://docs.sun.com/app/docs/doc/819-5461/gazgd?a=view If you want to reduce the steps in the future, you can enable the autoreplace property on the pool and all you need to do is physically replace the disks in the pool.

Cindy: AWESOME! Didn't know about that property, I'll make sure I set it :). All I did to replace the drives was to power off the machine (the failed drive had hard-locked the SCSI bus, so I had to anyways). Once the machine was powered off, I pulled the bad drive, inserted the new drive, and powered the machine on. That's when the machine came up showing the pool in a corrupted state. I'm assuming if I had removed the old drive, booted it with the drive missing, let it come up DEGRADED, and then inserted the new drive and did a zpool replace, it would have been fine. So I was going by the guess that zpool didn't know that the disk was replaced, and I was just curious why. -- This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
