similar to: OpenSolaris 2008.11 - resilver still restarting

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

Hi all, Sorry for the newbie question, but I''ve looked at the docs and haven''t been able to find an answer for this. I''m working with a system where the pool has already been configured and want to determine what the configuration is. I had thought that''d be with zpool status -v <poolname>, but it doesn''t seem to agree with the

Hi experts zpool import shows some weird config of an old zpool bash-3.00# zpool import pool: data1 id: 7539031628606861598 state: FAULTED status: One or more devices are missing from the system. action: The pool cannot be imported.

Hi all I have installed a new server with 77 2TB drives in 11 7-drive RAIDz2 VDEVs, all on WD Black drives. Now, it seems two of these drives were bad, one of them had a bunch of errors, the other was very slow. After zfs offlining these and then zfs replacing them with online spares, resilver ended and I thought it''d be ok. Appearently not. Albeit the resilver succeeds, the pool status

Currently I''m trying to figure out the best zfs layout for a thumper wrt. to read AND write performance. I did some simple mkfile 512G tests and found out, that per average ~ 500 MB/s seems to be the maximum on can reach (tried initial default setup, all 46 HDDs as R0, etc.). According to http://www.amd.com/us-en/assets/content_type/DownloadableAssets/ArchitectureWP_062806.pdf I would

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

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

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 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

This must be resliver day :) I just had a drive failure. The hot spare kicked in, and access to the pool over NFS was effectively zero for about 45 minutes. Currently the pool is still reslivering, but for some reason I can access the file system now. Resliver speed has been beaten to death I know, but is there a way to avoid this? For example, is more enterprisy hardware less susceptible to

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

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

In the process of replacing a raidz1 of four 500GB drives with four 1.5TB drives on the third one I ran into an interesting issue. The process was to remove the old drive, put the new drive in and let it rebuild. The problem was the third drive I put in had a hardware fault. That caused both drives (c4t2d0) to show as FAULTED. I couldn''t put a new 1.5TB drive in as a replacement -

Hi, I deployed ZFS on our mailserver recently, hoping for eternal peace after running on UFS and moving files witch each TB added.

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. OSOL 2009.06 Intel SASUC8i (w LSI 1.30IT FW) Gigabyte

Is there any way to stop a resilver? We gotta stop this thing - at minimum, completion time is 300,000 hours, and maximum is in the millions. Raidz2 array, so it has the redundancy, we just need to get data off. -------------- next part -------------- An HTML attachment was scrubbed...
