c3t21d0 INUSE currently in use
The spare is in use, altought there is no failed disk in the pool.
Can anyone "interpret" this ? Is this a bug ?
Thanks,
Robert

[zfs-discuss] Spare in use althought disk is healthy ?
Hi Lutz, You can try the following commands to see what happened: 1. Someone else replaced the disk with a spare, which would be recorded in this command: # zpool history -l zfs01vol 2. If the disk had some transient outage then maybe the spare kicked in. Use the following command to see if something happened to this disk: # fmdump -eV This command might produce a lot of output, but look for c3t12d0 occurrences. 3. If the c3t12d0 disk is okay, try detaching the spare back to the spare pool like this: # zpool detach zfs01vol c3t21d0 Thanks, Cindy On 04/26/10 15:41, Lutz Schumann wrote:> Hello list, > > a pool shows some strange status: > > volume: zfs01vol > state: ONLINE > scrub: scrub completed after 1h21m with 0 errors on Sat Apr 24 04:22:38 > 2010 > config: > > NAME STATE READ WRITE CKSUM > zfs01vol ONLINE 0 0 0 > mirror ONLINE 0 0 0 > c2t4d0 ONLINE 0 0 0 > c3t4d0 ONLINE 0 0 0 > mirror ONLINE 0 0 0 > c2t5d0 ONLINE 0 0 0 > c3t5d0 ONLINE 0 0 0 > mirror ONLINE 0 0 0 > c2t8d0 ONLINE 0 0 0 > c3t8d0 ONLINE 0 0 0 > mirror ONLINE 0 0 0 > c2t9d0 ONLINE 0 0 0 > c3t9d0 ONLINE 0 0 0 > mirror ONLINE 0 0 0 > c2t12d0 ONLINE 0 0 0 > spare ONLINE 0 0 0 > c3t12d0 ONLINE 0 0 0 > c3t21d0 ONLINE 0 0 0 > mirror ONLINE 0 0 0 > c2t13d0 ONLINE 0 0 0 > c3t13d0 ONLINE 0 0 0 > mirror ONLINE 0 0 0 > c2t16d0 ONLINE 0 0 0 > c3t16d0 ONLINE 0 0 0 > mirror ONLINE 0 0 0 > c2t17d0 ONLINE 0 0 0 > c3t17d0 ONLINE 0 0 0 > mirror ONLINE 0 0 0 > c2t20d0 ONLINE 0 0 0 > c3t20d0 ONLINE 0 0 0 > logs ONLINE 0 0 0 > mirror ONLINE 0 0 0 > c2t0d0 ONLINE 0 0 0 > c3t0d0 ONLINE 0 0 0 > mirror ONLINE 0 0 0 > c2t1d0 ONLINE 0 0 0 > c3t1d0 ONLINE 0 0 0 > cache > c0t0d0 ONLINE 0 0 0 > c0t1d0 ONLINE 0 0 0 > c0t2d0 ONLINE 0 0 0 > spares > c2t21d0 AVAIL > c3t21d0 INUSE currently in use > > The spare is in use, altought there is no failed disk in the pool. > > Can anyone "interpret" this ?

Hello, thanks for the feedback and sorry for the delay in answering. I checked the log and the fmadm. It seems the log does not show changes, however fmadm shows: Apr 23 2010 18:32:26.363495457 ereport.io.scsi.cmd.disk.dev.rqs.derr Apr 23 2010 18:32:26.363482031 ereport.io.scsi.cmd.disk.recovered Same thing for the other disk: Apr 21 2010 15:02:24.117303285 ereport.io.scsi.cmd.disk.dev.rqs.derr Apr 21 2010 15:02:24.117300448 ereport.io.scsi.cmd.disk.recovered It seems there is a VERY short temp error. I will try to detach this. Is this a Bug ? Robert -- This message posted from opensolaris.org

Hi Robert, Could be a bug. What kind of system and disks are reporting these errors?
