[zfs-discuss] How to recover -- LUNs go offline, now permanent errors?
I recently had an issue with my LUNs from our storage unit going offline. This caused the zpool to get numerous errors on the luns. The pool is on-line, and I did a scrub, but one of the raid sets is degraded: raidz2-3 DEGRADED 0 0 0 c7t60001FF011C6F3103B00011D1BF1d0 DEGRADED 0 0 0 too many errors c7t60001FF011C6F3023900011D1BF1d0 DEGRADED 0 0 0 too many errors c7t60001FF011C6F2F53700011D1BF1d0 DEGRADED 0 0 0 too many errors c7t60001FF011C6F2E43500011D1BF1d0 DEGRADED 0 0 0 too many errors c7t60001FF011C6F2D23300011D1BF1d0 DEGRADED 0 0 0 too many errors c7t60001FF011C6F2A93100011D1BF1d0 DEGRADED 0 0 0 too many errors c7t60001FF011C6F29A2F00011D1BF1d0 DEGRADED 0 0 0 too many errors c7t60001FF011C6F2682D00011D1BF1d0 DEGRADED 0 0 0 too many errors c7t60001FF011C6F24C2B00011D1BF1d0 DEGRADED 0 0 0 too many errors c7t60001FF011C6F2192900011D1BF1d0 DEGRADED 0 0 0 too many errors Also I have the following: errors: Permanent errors have been detected in the following files: <0x3a>:<0x3b04> Originally, there was a file, and then a directory listed, but I removed them.

Re: [zfs-discuss] Zpool metadata corruption from S10U9 to S11 express
An update: I had mirrored my boot drive when I installed Solaris 10U9 originally, so I went ahead and rebooted the system to this disk instead of my Solaris 11 install. After getting the system up, I imported the zpool, and everything worked normally. So I guess there is some sort of incompatibility between Solaris 10 and Solaris 11. I would have thought that Solaris 11 could import an older pool level. Any other insight on importing pools between these two versions of Solaris would be helpful.

I was recently running Solaris 10 U9 and I decided that I would like to go to Solaris 11 Express so I exported my zpool, hoping that I would just do an import once I had the new system installed with Solaris 11.

[zfs-discuss] Replacing a Lun (Raid 0) (Santricity)
I would like advise about how to replace a raid 0 lun. The lun is basically a raid 0 lun which is from a single disk volume group / volume from our Flexline 380 unit. So every disk in the unit is a volume group/volume/lun mapped to the host. We then let ZFS do the raid. We have a lun now which has been getting read errors and basically the underlying drive needs to be replaced. I've done this in the past but as I remember it was cumbersome and didn't go that smoothly so I would like some advise about how to go about it. As I recall if you just fail the disk via Santricity, the lun really doesn't go offline from a host point of via and hence ZFS still tries to write to the lun/disk. I believe I either unmapped the lun to the host at which point ZFS kicked in a hot spare, or I offlined the disk via ZFS first. Then at that point the drive can be replace on the storage and the volume re-initialized then remapped back to the host. So part of my question... does the above sound reasonable, or should I be doing this differently? Also I'm a little unsure about how to get the original lun back in operation and the spare back to a spare. For example I have the following situation now: raidz2 ONLINE 0 0 0 c10t600A0B80001139967CF945E80E95d0ONLINE 0 0 0 c10t600A0B8000115EA2FEEB45E8145Ed0ONLINE 0 0 0 spare ONLINE 0 0 0 c10t600A0B80001139967D2345E81075d0 ONLINE 0 0 0 c10t600A0B80001139967CE145E80D4Dd0 ONLINE 0 0 0 c10t600A0B80001139967D3F45E81157d0ONLINE 0 0 0 c10t600A0B8000115EA2FF1145E817BEd0ONLINE 0 0 0 c10t600A0B80001139967D5D45E813EBd0ONLINE 0 0 0 c10t600A0B8000115EA2FE7D45E80CDEd0ONLINE 0 0 0 c10t600A0B80001139967C6145E808C7d0ONLINE 0 0 0 c10t600A0B8000115EA2FE9945E80E6Ad0ONLINE 0 0 0 c10t600A0B80001139967C8B45E80A59d0ONLINE 0 0 0 c10t600A0B80001139967CA745E80B21d0ONLINE 0 0 0 c10t600A0B8000115EA2FEB545E810D4d0ONLINE 0 0 0 c10t600A0B80001139967CD145E80CD7d0ONLINE 0 0 0 c10t600A0B8000115EA2FED145E8129Cd0ONLINE 0 0 0 c10t600A0B80001139967CFB45E80EA5d0ONLINE 0 0 0 c10t600A0B8000115EA2FEED45E8146Ed0ONLINE 0 0 0 spares c10t600A0B80001139967CE145E80D4Dd0 INUSE currently in use c10t600A0B8000115EA2FEE145E81328d0 AVAIL c10t600A0B80001139967D0B45E80F21d0 AVAIL c10t600A0B8000115EA2FEFD45E81506d0 AVAIL c10t600A0B80001139967D3545E81107d0 AVAIL c10t600A0B80001139967D5345E81289d0 AVAIL c10t600A0B8000115EA2FF2345E81864d0 AVAIL c10t600A0B80001139967D6F45E8149Bd0 AVAIL I thought if I replace the original device with the same (but new) lun that should work, but I get the following: zpool replace tank c10t600A0B80001139967D2345E81075d0 c10t600A0B80001139967D2345E81075d0 invalid vdev specification use '-f' to override the following errors: /dev/dsk/c10t600A0B80001139967D2345E81075d0s0 is part of active ZFS pool tank.

Re: [zfs-discuss] remove snapshots
To list your snapshots: /usr/sbin/zfs list -H -t snapshot -o name Then you could use that in a for loop: for i in `/usr/sbin/zfs list -H -t snapshot -o name` ; do echo "Destroying snapshot: $i" /usr/sbin/zfs destroy $i done The above would destroy all your snapshots.

Re: [zfs-discuss] Again ZFS with expanding LUNs!
I don't believe LUN expansion is quite yet possible under Solaris 10 (11/06). I believe this might make it into the next update but I'm not sure on that. Someone from Sun would need to comment on when this will make it into the production release of Solaris. I know this because I was working with a person from Sun testing a utility which will detect the larger LUN and update the disk label. Then at that point if you export the pool and import it again the added space will show up. The utility was just for testing however. I'm waiting as well for the automatic LUN expansion stuff.

James, Thanks for the reply. It looks like now the scrub has completed. Should I now clear these warnings? bash-3.00# zpool status -x pool: mypool state: ONLINE status: One or more devices has experienced an unrecoverable error. An attempt was made to correct the error. Applications are unaffected. action: Determine if the device needs to be replaced, and clear the errors using 'zpool clear' or replace the device with 'zpool replace'. see: http://www.sun.com/msg/ZFS-8000-9P scrub: scrub completed with 0 errors on Sun Sep 10 07:44:36 2006 config: NAMESTATE READ WRITE CKSUM mypoolONLINE 0 0 0 raidz ONLINE 0 0 0 c10t600A0B800011730E66C544C5EBB8d0 ONLINE 0 0 0 c10t600A0B800011730E66CA44C5EBEAd0 ONLINE 0 0 0 c10t600A0B800011730E66CF44C5EC1Cd0 ONLINE 0 0 0 c10t600A0B800011730E66D444C5EC5Cd0 ONLINE 0 0 0 c10t600A0B800011730E66D944C5ECA0d0 ONLINE 0 0 0 c10t600A0B800011652EE5C144C5ECDFd0 ONLINE 0 0 0 c10t600A0B800011730E66E244C5ED2Cd0 ONLINE 0 0 0 c10t600A0B800011652EE5C644C5ED87d0 ONLINE 0 0 0 c10t600A0B800011730E66EB44C5EDD8d0 ONLINE 0 0 0 c10t600A0B800011652EE5CB44C5EE29d0 ONLINE 0 0 0 c10t600A0B800011730E66F444C5EE7Ed0 ONLINE 0 015 c10t600A0B800011652EE5D044C5EEC9d0 ONLINE 0 0 0 c10t600A0B800011730E66FD44C5EF1Ad0 ONLINE 50 0 0 c10t600A0B800011652EE5D544C5EF63d0 ONLINE 0 0 0 raidz ONLINE 0 0 0 c10t600A0B800011652EE5B844C5EBCBd0 ONLINE 0 0 0 c10t600A0B800011652EE5BA44C5EBF5d0 ONLINE 0 0 0 c10t600A0B800011652EE5BC44C5EC2Dd0 ONLINE 0 0 0 c10t600A0B800011652EE5BE44C5EC6Bd0 ONLINE 0 0 0 c10t600A0B800011730E66DB44C5ECB4d0 ONLINE 0 0 0 c10t600A0B800011652EE5C344C5ECF9d0 ONLINE 0 0 0 c10t600A0B800011730E66E444C5ED5Ad0 ONLINE 0 0 0 c10t600A0B800011652EE5C844C5EDA1d0 ONLINE 0 0 0 c10t600A0B800011730E66ED44C5EDFAd0 ONLINE 0 0 0 c10t600A0B800011652EE5CD44C5EE47d0 ONLINE 0 0 0 c10t600A0B800011730E66F644C5EE96d0 ONLINE 0 014 c10t600A0B800011652EE5D244C5EEE7d0 ONLINE 0 0 0 c10t600A0B800011730E66FF44C5EF32d0 ONLINE 70 0 0 c10t600A0B800011652EE5D744C5EF7Fd0 ONLINE 0 0 0 David This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
[zfs-discuss] Corrupted LUN in RAIDZ group -- How to repair?
Background: We have a ZFS pool setup from LUNS which are from a SAN connected StorageTek/Engenio Flexline 380 storage system. Just this past Friday the storage environment went down causing the system to go down. After looking at the storage environment, we had several volume groups which needed to be carefully put back together to prevent corruption. Well, one of the volume groups and the volumes/LUNs coming from it got corrupted. Since our ZFS pools is setup to only have a LUN from each volume group we basically ended up with a single disk loss in our RAIDZ group. So I believe we should be able to recover from this. My question is how to replace this disk (LUN). Basically the LUN is again okay, but the data on the LUN is not. I have tried to do a zpool replace, but ZFS seems to know that the disk/lun is the same device. Using a -f (force) didn't work either. How does one replace a LUN with ZFS? I'm currently doing a "scrub", but don't know if that will help. I first just had read errors on a lun in the raidz group, but just tonight noticed that I now have a checksum error on another lun as well. (see zpool status command output below) Below is a zpool status -x output. Can anyone advise how to recover from this? # zpool status -x pool: mypool state: ONLINE status: One or more devices has experienced an unrecoverable error. An attempt was made to correct the error. Applications are unaffected. action: Determine if the device needs to be replaced, and clear the errors using 'zpool clear' or replace the device with 'zpool replace'. see: http://www.sun.com/msg/ZFS-8000-9P scrub: scrub in progress, 66.00% done, 10h45m to go config: NAMESTATE READ WRITE CKSUM mypoolONLINE 0 0 0 raidz ONLINE 0 0 0 c10t600A0B800011730E66C544C5EBB8d0 ONLINE 0 0 0 c10t600A0B800011730E66CA44C5EBEAd0 ONLINE 0 0 0 c10t600A0B800011730E66CF44C5EC1Cd0 ONLINE 0 0 0 c10t600A0B800011730E66D444C5EC5Cd0 ONLINE 0 0 0 c10t600A0B800011730E66D944C5ECA0d0 ONLINE 0 0 0 c10t600A0B800011652EE5C144C5ECDFd0 ONLINE 0 0 0 c10t600A0B800011730E66E244C5ED2Cd0 ONLINE 0 0 0 c10t600A0B800011652EE5C644C5ED87d0 ONLINE 0 0 0 c10t600A0B800011730E66EB44C5EDD8d0 ONLINE 0 0 0 c10t600A0B800011652EE5CB44C5EE29d0 ONLINE 0 0 0 c10t600A0B800011730E66F444C5EE7Ed0 ONLINE 0 0 9 c10t600A0B800011652EE5D044C5EEC9d0 ONLINE 0 0 0 c10t600A0B800011730E66FD44C5EF1Ad0 ONLINE 50 0 0 c10t600A0B800011652EE5D544C5EF63d0 ONLINE 0 0 0 raidz ONLINE 0 0 0 c10t600A0B800011652EE5B844C5EBCBd0 ONLINE 0 0 0 c10t600A0B800011652EE5BA44C5EBF5d0 ONLINE 0 0 0 c10t600A0B800011652EE5BC44C5EC2Dd0 ONLINE 0 0 0 c10t600A0B800011652EE5BE44C5EC6Bd0 ONLINE 0 0 0 c10t600A0B800011730E66DB44C5ECB4d0 ONLINE 0 0 0 c10t600A0B800011652EE5C344C5ECF9d0 ONLINE 0 0 0 c10t600A0B800011730E66E444C5ED5Ad0 ONLINE 0 0 0 c10t600A0B800011652EE5C844C5EDA1d0 ONLINE 0 0 0 c10t600A0B800011730E66ED44C5EDFAd0 ONLINE 0 0 0 c10t600A0B800011652EE5CD44C5EE47d0 ONLINE 0 0 0 c10t600A0B800011730E66F644C5EE96d0 ONLINE 0 0 6 c10t600A0B800011652EE5D244C5EEE7d0 ONLINE 0 0 0 c10t600A0B800011730E66FF44C5EF32d0 ONLINE 70 0 0 c10t600A0B800011652EE5D744C5EF7Fd0 ONLINE 0 0 0 This system is at Solaris 10, U2.
