I have a hot spare that was part of my zpool but is no longer
connected to the system. I can run the zpool remove command and it
returns fine but doesn''t seem to do anything.
I have tried adding and removing spares that are connected to the
system and works properly. Is zpool remove failing because the disk is
no longer connected to the system?

Hi, Christopher, I tried by using raw files as the spare, remove the file, then ''zpool remove'' , looks the raw files could be eliminated from the pool. But since you use the physical device, I suppose it might be a bug there, for the status of spare device has turned to be ''UNAVAIL''. Could you point out the OS you used? I might check with the latest onnv nightly to see if this issue exist. Christopher Gibbs wrote:> I have a hot spare that was part of my zpool but is no longer > connected to the system.

The pool was exported from snv_73 and the spare was disconnected from the system. The OS was upgraded to snv_79b (SXDE 1/08) and the pool was re-imported. I think this weekend I''ll try connecting a different drive to that controller and see if it will remove then. Thanks for your help.

Oops, I forgot a step. I also upgraded the zpool in snv79b before I tried the remove. It is now version 10.

Hi, Christ, I just verified this issue could simply reproduce in onnv, I''ve filed CR #6664649 to trace it. Thanks for report. # zpool create -f tank c3t5d0s1 spare c3t5d0s0 # mkfile 100m /var/tmp/file # zpool add tank sparc /var/tmp/file # zpool export tank # format c3t5d0 ( modify c3t5d0s0 to be unassigned) # rm /var/tmp/file # zpool import tank # zpool status -v tank pool: tank state: ONLINE scrub: none requested config: NAME STATE READ WRITE CKSUM tank ONLINE 0 0 0 c3t5d0s1 ONLINE 0 0 0 spares c3t5d0s0 UNAVAIL cannot open /var/tmp/file UNAVAIL cannot open If the sparce device status as UNAVAIL, it cannot be removed by ''zpool remove'', even I tried ''zpool scrub'' and get no help. # zpool remove tank c3t5d0s0 # echo $? 0 # zpool remove tank /var/tmp/file # echo $? 0 # zpool status -v tank pool: tank state: ONLINE scrub: none requested config: NAME STATE READ WRITE CKSUM tank ONLINE 0 0 0 c3t5d0s1 ONLINE 0 0 0 spares c3t5d0s0 UNAVAIL cannot open /var/tmp/file UNAVAIL cannot open Christopher Gibbs wrote: Oops, I forgot a step.
