similar to: zfs snapshot restarts scrubbing?

Hi there, I am currently evaluating OpenSolaris as a replacement for my linux installations. I installed it as a xen domU, so there is a remote chance, that my observations are caused by xen. First, my understanding of "zpool [i]scrub[/i]" is "Ok, go ahead, and rewrite [b]each block of each device[/b] of the zpool". Whereas "[i]resilvering[/i]" means "Make

Just look at this. I thought all the restarting resilver bugs were fixed, but it looks like something odd is still happening at the start: Status immediately after starting resilver: # zpool status pool: rc-pool state: DEGRADED status: One or more devices has experienced an unrecoverable error. An attempt was made to correct the error. Applications are unaffected. action: Determine

Hi. I''m working on getting the most recent ZFS to the FreeBSD''s CVS. Because of the huge amount of changes, I decided to work on ZFS regression tests, so I''m more or less sure nothing broke in the meantime. (Yes, I know about ZFS testsuite, but unfortunately I wasn''t able to port it to FreeBSD, it was just too much work. I''m afraid it is too

I''m building a system with two Apple RAIDs attached. I have hardware RAID5 configured so no RAIDZ or RAIDZ2, just a basic zpool pointing at the four LUNs representing the four RAID controllers. For on-going maintenance, will a zpool scrub be of any benefit? From what I''ve read with this layer of abstration ZFS is only maintaining the metadata and not the actual data on the

Hi list, Here''s my case : pool: mypool state: DEGRADED status: One or more devices is currently being resilvered. The pool will continue to function, possibly in a degraded state. action: Wait for the resilver to complete. scrub: resilver in progress for 147h19m, 100.00% done, 0h0m to go config: NAME STATE READ WRITE CKSUM filerbackup13

I''ve got a Thumper running snv_57 and a large ZFS pool. I recently noticed a drive throwing some read errors, so I did the right thing and zfs replaced it with a spare. Everything went well, but the resilvering process seems to be taking an eternity: # zpool status pool: bigpool state: ONLINE status: One or more devices has experienced an unrecoverable error. An attempt was

Hello, Has anyone encountered the following error message, running Solaris 10 u8 in an LDom. bash-3.00# devfsadm devfsadm: write failed for /dev/.devfsadm_dev.lock: Bad exchange descriptor bash-3.00# zpool status -v rpool pool: rpool state: DEGRADED status: One or more devices has experienced an error resulting in data corruption.

I have a system running in a VM with a root pool. The root pool occasionally shows a fairly stern warning. This warning comes with no check sum errors. bash-3.00# zpool status -vx pool: rpool state: ONLINE status: One or more devices has experienced an error resulting in data corruption. Applications may be affected. action: Restore the file in question if possible. Otherwise restore

Hi, once I created a zpool of single vdevs not using mirroring of any kind. Now I wonder if it''s possible to add vdevs and mirror the currently existing ones. Thanks, budy -- This message posted from opensolaris.org

Hey folks, While scrubbing, zpool status shows nearly 40MB "repaired" but 0 in each of the read/write/checksum columns for each disk. One disk has "(repairing)" to the right but once the scrub completes there''s no mention that anything ever needed fixing. Any idea what would need to be repaired on that disk? Are there any other types of errors besides

While testing a zpool with a different storage adapter using my "blkdev" device, I did a test which made a disk unavailable -- all attempts to read from it report EIO. I expected my configuration (which is a 3 disk test, with 2 disks in a RAIDZ and a hot spare) to work where the hot spare would automatically be activated. But I''m finding that ZFS does not behave this way

So, my Areca controller has been complaining via email of read errors for a couple days on SATA channel 8. The disk finally gave up last night at 17:40. I got to say I really appreciate the Areca controller taking such good care of me. For some reason, I wasn''t able to log into the server last night or in the morning, probably because my home dir was on the zpool with the failed disk

After several days of trying to get a 1.5TB drive to resilver and it continually restarting, I eliminated all of the snapshot-taking facilities which were enabled and 2009-10-29.14:58:41 [internal pool scrub done txg:567780] complete=0 2009-10-29.14:58:41 [internal pool scrub txg:567780] func=1 mintxg=3 maxtxg=567354 2009-10-29.16:52:53 [internal pool scrub done txg:567999] complete=0

Hello everyone, As one of the steps of improving my ZFS home fileserver (snv_134) I wanted to replace a 1TB disk with a newer one of the same vendor/model/size because this new one has 64MB cache vs. 16MB in the previous one. The removed disk will be use for backups, so I thought it''s better off to have a 64MB cache disk in the on-line pool than in the backup set sitting off-line all

Hi all, I''m trying to delete a zpool and when I do, I get this error: # zpool destroy oradata_fs1 cannot open ''oradata_fs1'': I/O error # The pools I have on this box look like this: #zpool list NAME SIZE USED AVAIL CAP HEALTH ALTROOT oradata_fs1 532G 119K 532G 0% DEGRADED - rpool 136G 28.6G 107G 21% ONLINE - # Why

Chapter 9, "Troubleshooting and Data Recovery", p.115 states: "To enable background scrubbing, use the zpool set command: # zpool set scrub=2w The parameter is a time duration indicating how often a complete scrub should be performed. In this case, the administrator is requesting that the pool be scrubbed once every two weeks. ZFS automatically tries to schedule I/O to even

Dear all Is there a way to stop a running scrub on a zfs pool? Same question applies to a running resilver. Both render our fileserver unusable due to massive CPU load so we''d like to postpone them. In the docs it says that resilvering and scrubbing survive a reboot, so I am not even sure if a reboot would stop scrubbing or resilvering. Any help greatly appreciated! Cheers, Thomas

Hi, to shorten the story, I describe the situation. I have 4 disks in a zfs/svm config: c2t9d0 9G c2t10d0 9G c2t11d0 18G c2t12d0 18G c2t11d0 is devided in two: selecting c2t11d0 [disk formatted] /dev/dsk/c2t11d0s0 is in use by zpool storedge. Please see zpool(1M). /dev/dsk/c2t11d0s1 is part of SVM volume stripe:d11. Please see metaclear(1M). /dev/dsk/c2t11d0s2 is in use by zpool storedge. Please

I have a weekly scrub setup, and I''ve seen at least once now where it says "don''t snapshot while scrubbing" Is this a data integrity issue, or will it make one or both of the processes take longer? Thanks
