[zfs-discuss] Bad pool...
Hi all I have a rather large pool that has been a bit troublesome. We've lost some drives (WD Black), and though that should work out well, I now have a pool that doesn't look too healthy. http://paste.ubuntu.com/611973/ Two drives have been resilvered, but the old drives still stick. The drive that has died still hasn't been taken over by a spare, although the two spares show up as AVAIL. Anyone that know how I can fix this?

Two drives have been resilvered, but the old drives still stick. The drive that has died still hasn't been taken over by a spare, although the two spares show up as AVAIL. For the one that hasn't been replaced try doing: zpool replace dbpool c8t24d0 c4t43d0 For the two that have already been replaced you can try: zpool detach dbpool c4t1d0/old zpool detach dbpool c4t6d0/old If that doesn't work then you need the disk ID from the old disks and use that in the detach command instead of the c4t1d0 id. -Don ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
Re: [zfs-discuss] Bad pool...
Shouldn't ZFS detach these automatically? It has done so earlier... It is not supposed to- at least that I recall. Earlier replaces have gone well. One thing is spares, which I can understand somewhat, but dead drives should definetely be tossed off when replaced Vennlige hilsener / Best regards roy -- Roy Sigurd Karlsbakk (+47) 97542685 r...@karlsbakk.net http://blogg.karlsbakk.net/ -- I all pedagogikk er det essensielt at pensum presenteres intelligibelt.

Re: [zfs-discuss] Bad pool...
The system became non-responsible after two drives was lost, and replaced with spares, in that VDEV. That bug has been filed and acknowleged. Take a RAIDz2 with two spares and remove a drive from the pool, let it resilver to a spare, remove another, wait until it resilvers again, and remove the third. The system will become rather dead - even the rpool will be unavailable, even if both the data pool and the rpool are bothe theoretically healthy Can't say I've ever run into that situation. I'd suggest looking into the pool failmode setting but that still wouldn't make a lot of sense. Any idea why you are getting so many failures? CC:ing this to the appropriate lists As a first, the default is to let go of failed devices. I haven't tweaked that part, nor any part of the pool. If a drive failes, it should be replaced by a spare, and when a drive is replaced by a new one, the old ghost should disappear. Neither of this happens at times. It seems sometimes the zpool forgets a dead drive and let ihang. This may trigger the bug which turns a pool and indeed the system unusable (if two drives in a raidz2 are lost, but resilvererd, losing the third will hang the system). The remedy seemed to be to zpool detach the drives. Still, the bug(s) exist(s) to allow a system to be rendered unusable just with a few drives lost, long before the pool is lost.
