similar to: Excruciatingly slow resilvering on X4540 (build 134)

While I understand everything at Oracle is "top secret" these days. Does anyone have any insight into a next-gen X4500 / X4540? Does some other Oracle / Sun partner make a comparable system that is fully supported by Oracle / Sun? http://www.oracle.com/us/products/servers-storage/servers/previous-products/index.html What do X4500 / X4540 owners use if they''d like more

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

Hi list, First off: # cat /etc/release Solaris 10 6/06 s10x_u2wos_09a X86 Copyright 2006 Sun Microsystems, Inc. All Rights Reserved. Use is subject to license terms. Assembled 09 June 2006 Here''s an (almost) disaster scenario that came to life over the past week. We have a very large zpool

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

Sorry for the off-topic question. I''m needing to replace a disk in a x4540 zfs file system. I have replacement ST31000NSSUN disks, but it''s not obvious to me how to separate the original disk from its drive sled, it seems to be attached by more than the usual 4 screws. Is it meant to be separated? I''ve looked the x4540 user guide but it does not say anything about it.

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

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

We''re using some X4540s, with OpenSolaris 2008.11. According to my testing, to optimize our systems for our specific workload, I''ve determined that we get the best performance with the write cache disabled on every disk, and with zfs:zfs_nocacheflush=1 set in /etc/system. The only issue is setting the write cache permanently, or at least quickly. Right now, as it is,

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:

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

I have a situation where my zpool (with two radiz2s) is resilvering and reaches a certain point, then starts over. There no read, write or checksum errors. The disks do have a fair amount of resilvering to do, as I''ve had a variety of disk failures. But at the core of things, there''s enough parity data to avoid data loss, and the zpool is functioning fine, albeit in a

Has anyone worked with a x4500/x4540 and know if the internal raid controllers have a bbu? I''m concern that we won''t be able to turn off the write-cache on the internal hds and SSDs to prevent data corruption in case of a power failure. -- This message posted from opensolaris.org

Oracle have deleted the best ZFS platform I know, the X4540. Does anyone know of an equivalent system? None of the current Oracle/Sun offerings come close. -- Ian.

Is there any way to control the resliver speed? Having attached a third disk to a mirror (so I can replace the other disks with larger ones) the resilver goes at a fraction of the speed of the same operation using disk suite. However it still renders the system pretty much unusable for anything else. So I would like to control the rate of the resilver. Either slow it down a lot so that the

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 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

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 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

So, when you add a log device to a pool, it initiates a resilver. What is it actually doing, though? Isn''t the slog a copy of the in-memory intent log? Wouldn''t it just simply replicate the data that''s in the other log, checked against what''s in RAM? And presumably there isn''t that much data in the slog so there isn''t that much to check? Or

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.
