I know this topic has been discussed many times... but what the hell makes zpool resilvering so slow? I''m running OpenSolaris 2009.06. I have had a large number of problematic disks due to a bad production batch, leading me to resilver quite a few times, progressively replacing each disk as it dies (and now preemptively removing disks.) My complaint is that resilvering ends up

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

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

Hello All I read this thread Resilver/scrub times? for a few minutes and I have recognize that I dont know the different between Resilvering and Scrubing. Shame on me. :-( I dont find some declarations in the man-pages and I know the command to start scrubing "zpool scrub tank" but what is the command to start resilver and what is the different? -- Best Regards Alexander Dezember, 20

I''m in well over my head with this report from zpool status saying: root # zpool status z3 pool: z3 state: DEGRADED 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 the entire pool from backup. see: http://www.sun.com/msg/ZFS-8000-8A

Hi all I''m seeing some rather bad resilver times for a pool of WD Green drives (I know, bad drives, but leave that). Does resilver go through the whole pool or just the VDEV in question? -- Vennlige hilsener / Best regards roy -- Roy Sigurd Karlsbakk (+47) 97542685 roy at karlsbakk.net http://blogg.karlsbakk.net/ -- I all pedagogikk er det essensielt at pensum presenteres

hi, i have raid1 on zfs with 2 device on pool first device died and boot from second not working... i try to get http://mfsbsd.vx.sk/ flash and load from it with zpool import http://puu.sh/2402E when i load zfs.ko and opensolaris.ko i see this message: Solaris: WARNING: Can''t open objset for zroot/var/crash Solaris: WARNING: Can''t open objset for zroot/var/crash zpool status:

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 am curious why zpool status reports a pool to be in the DEGRADED state after a drive in a raidz2 vdev has been successfully replaced. In this particular case drive c0t6d0 was failing so I ran, zpool offline home/c0t6d0 zpool replace home c0t6d0 c8t1d0 and after the resilvering finished the pool reports a degraded state. Hopefully this is incorrect. At this point is the vdev in question now has

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

Hello, I''m working with someone who replaced a failed 1TB drive (50% utilized), on an X4540 running OS build 134, and I think something must be wrong. Last Tuesday afternoon, zpool status reported: scrub: resilver in progress for 306h0m, 63.87% done, 173h7m to go and a week being 168 hours, that put completion at sometime tomorrow night. However, he just reported zpool status shows:

Hi all, I recently experienced a disk failure on my home server and observed checksum errors while resilvering the pool and on the first scrub after the resilver had completed. Now everything seems fine but I''m posting this to get help with calming my nerves and detect any possible future faults. Lets start with some specs.

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

I just got a call from another of our admins, as I am the resident ZFS expert, and they have opened a support case with Oracle, but I figured I''d ask here as well, as this forum often provides better, faster answers :-) We have a server (M4000) with 6 FC attached SE-3511 disk arrays (some behind a 6920 DSP engine). There are many LUNs, all about 500 GB and mirrored via ZFS. The LUNs

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

I currently have a 7x1.5tb raidz1. I want to add "phase 2" which is another 7x1.5tb raidz1 Can I add the second phase to the first phase and basically have two raid5''s striped (in raid terms?) Yes, I probably should upgrade the zpool format too. Currently running snv_104. Also should upgrade to 110. If that is possible, would anyone happen to have the simple command lines to

Hi all! I''ve decided to take the "big jump" and build a ZFS home filer (although it might also do "other work" like caching DNS, mail, usenet, bittorent and so forth). YAY! I wonder if anyone can shed some light on how long a pool scrub would take on a fairly decent rig. These are the specs as-ordered: Asus P5Q-EM mainboard Core2 Quad 2.83 GHZ 8GB DDR2/80 OS: 2 x

The vendor wanted to come in and replace an HDD in the 2nd X4500, as it was "constantly busy", and since our x4500 has always died miserably in the past when a HDD dies, they wanted to replace it before the HDD actually died. The usual was done, HDD replaced, resilvering started and ran for about 50 minutes. Then the system hung, same as always, all ZFS related commands would just

When I booted my laptop up this morning it took much longer than normal and there was a lot of disk activity even after I logged in. A quick use of dtrace and iostat revealed that all the writes were to the zpool. I ran zpool status and found that the pool was resilvering. Strange thing is that while the pool is a mirror, one side of it is offline since it is on an external usb disk - which
