[zfs-discuss] ZFS : unable to mount a pool
Hello all, I have a critical ZFS problem, quick history I have a production machine which backplane has burnt (litteraly) that had 2 pools : "applis" & "storage". Those pools are RAIDz1 + 1 spare. Then we switched to the backup one, all right. Backup machine is the exact replica of production one, files are rsynced every night. I needed to reboot it to rename it, so I did. But reboot failed : zfs panic at boot. following sun's doc, I moved /etc/zfs/zpool.cache away, and reboot. All fine. Mounted pool "storage" without problem, but unable to mount pool "applis". Someone suggested disks were re-labelled, I'm open to all advices, If I can't get those datas back, all we be lost... Thanks for reading, and maybe helping. diagnostic outputs : (made from opensolaris liveCD, to have a recent ZFS) -- # zpool import pool: applis id: 5524311410139446438 state: UNAVAIL status: The pool was last accessed by another system. action: The pool cannot be imported due to damaged devices or data. see: http://www.sun.com/msg/ZFS-8000-EY config: applis UNAVAIL insufficient replicas raidz1FAULTED corrupted data c7t0d0 FAULTED corrupted data c7t1d0 FAULTED corrupted data c8t2d0 FAULTED corrupted data c8t3d0 FAULTED corrupted data spares c5t4d0 -- # prtvtoc /dev/rdsk/c7t0d0 * /dev/rdsk/c7t0d0 partition map * * Dimensions: * 512 bytes/sector * 976773168 sectors * 976773101 accessible sectors * * Flags: * 1: unmountable * 10: read-only * * Unallocated space: * First SectorLast * Sector CountSector * 34 222 255 * * First SectorLast * Partition Tag FlagsSector CountSector Mount Directory 0 400256 976756495 976756750 8 1100 976756751 16384 976773134 -- # fstyp /dev/rdsk/c7t0d0 unknown_fstyp (no match) -- # zpool import -f applis cannot import 'applis': one or more device is currently unavailable signature.asc Description: Ceci est une partie de message numériquement signée ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

I have been in the same situation, so I wrote a nagios plugin collecting event from FMd via SNMP. The purpose is a little wider than what you need (as it collects all FMd events) but if it can help see http://solaris-fr.org/home/docs/serveur/smpfmd (in french, sorry) If you need explanations due to language post here :) Hope it helps, -- Nicolas Szalay Administrateur systèmes & réseaux -- _ ASCII ribbon campaign ( ) - against HTML email X & vCards / \ signature.asc Description: Ceci est une partie de message numériquement signée ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

And solaris > didn't and doesn't see any actual hw errors on the disks, does it? I had the same symptoms recently. I also thought the disk were dying but I was wrong. Suspected the RAM, no. Finally it was because I mixed raid cards on different PCI buses : 2 64bits buses (no problem with these ones) and 1 32 Bits PCI bus which caused *all* the checksum errors. Kicked ou the card on the 32 bit PCI bus and all worked fine.

[zfs-discuss] add/replace : strange zfs pool behaviour
Hi everybody; I'm experimenting something weird on one of my zpool. One of my hard drive failed (c3t3d0). The hot spare (c4t3d0) did its job, I (physically) replaced it, and rebooted. I have acknowledged the failure with fmadm too.
