Hi all, I'm seeing some puzzling behaviour with my RAID-Z.
loki# uname -a FreeBSD loki.local 8.2-RELEASE-p1 FreeBSD 8.2-RELEASE-p1 #4: Sat Apr 30 10:39:46 PDT 2011 jpaet...@servant.ixsystems.com:/usr/home/jpaetzel/freenas/obj.amd64/usr/home/jpaetzel/freenas/FreeBSD/src/sys/FREENAS.amd64 amd64 loki# zpool status storage pool: storage state: DEGRADED scrub: none requested config: NAME STATE READ WRITE CKSUM storage DEGRADED 0 0 0 raidz1 DEGRADED 0 0 0 da2 ONLINE 0 0 0 replacing DEGRADED 0 0 0 da0/old OFFLINE 0 0 0 da0 ONLINE 0 0 0 da1 ONLINE 0 0 0 da3 ONLINE 0 0 0 da4 ONLINE 0 0 0 da5 ONLINE 0 0 0 cache da2 ONLINE 0 0 0 errors: No known data errors This was after a drive (da0) died, which I replaced, resilvered then upgraded the pool to v15. My strong belief is that da2 has always been a cache drive (a 256Gb SSD) and has never been a part of "storage". The drive labelled da2 in "storage" had previously been da6, but obviously there's now some kind of weird label duplication issue, in addition to a never ending "replacing" process for da0. loki# ls /dev/da? /dev/da0 /dev/da1 /dev/da2 /dev/da3 /dev/da4 /dev/da5 /dev/da6 All other da? drives are 2Tb spinning discs and seem to be in good working order. The filesystems are all accessible and operational with no corruption that I can see. It should be noted that da2 in the pool had 2 checksum errors prior to clearing and da2 in caches reported corruption immediately after I replaced da0. I've tried exporting/importing, scrubbing, clearing, removing da2, removing da0/old and even rebooting the whole machine. Not made any headway and stumped as to what I should try next. Any advice would be greatly appreciated. - Andrew _______________________________________________ zfs-discuss mailing list firstname.lastname@example.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
