similar to: Have my RMA... Now what??

I have a desktop system with 2 ZFS mirrors. One drive in one mirror is starting to produce read errors and slowing things down dramatically. I detached it and the system is running fine. I can''t tell which drive it is though! The error message and format command let me know which pair the bad drive is in, but I don''t know how to get any more info than that like the serial number

Well, I''ve searched my brains out and I can''t seem to find a reason for this. I''m getting bad to medium performance with my new test storage device. I''ve got 24 1.5T disks with 2 SSDs configured as a zil log device. I''m using the Areca raid controller, the driver being arcmsr. Quad core AMD with 16 gig of RAM OpenSolaris upgraded to snv_134. The 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

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

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

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 would like to knwon if with ZFS it''s possible to do something like that : http://tldp.org/HOWTO/LVM-HOWTO/removeadisk.html meaning : I have a zpool with 48 disks with 4 raidz2 (12 disk). Inside those 48 disk I''ve 36x 3T and 12 x 2T. Can I buy new 12x4 To disk put in the server, add in the zpool, ask zpool to migrate all data on those 12 old disk on the new and

I figure this group will know better than any other I have contact with, is 700-800 I/Ops reasonable for a 7200 RPM SATA drive (1 TB Sun badged Seagate ST31000N in a J4400) ? I have a resilver running and am seeing about 700-800 writes/sec. on the hot spare as it resilvers. There is no other I/O activity on this box, as this is a remote replication target for production data. I have a 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

I have a raidz2 and did a scrub, it took 8h. Then I reconnected some drives to other SATA ports, and now it takes 15h to scrub?? Why is that? -- This message posted from opensolaris.org

G''day, all, So, I''ve decided to migrate my home server from Linux+swRAID+LVM to Solaris+ZFS, because it seems to hold much better promise for data integrity, which is my primary concern. However, naturally, I decided to do some benchmarks in the process, and I don''t understand why the results are what they are. I though I had a reasonable understanding of ZFS, but now

I''m building another 24-bay rackmount storage server, and I''m considering what drives to put in the bays. My chassis is a Supermicro SC846A, so the backplane supports SAS or SATA; my controllers are LSI3081E, again supporting SAS or SATA. Looking at drives, Seagate offers an enterprise (Constellation) 2TB 7200RPM drive in both SAS and SATA configurations; the SAS model offers

I have a 9-bay JBOD configured as a raidz2. One of the disks, which is on-line and fine, needs to be swapped out and replaced. I have been looking though the zfs admin guide and am confused on how I should go about swapping out. I though I could put the disk off-line, remove it, put a new disk in, and put on-line. Does this sound right? Any help would be great Thanks Chris This message

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 have this server with some 50TB disk space. It originally had 30TB on WD Greens, was filled quite full, and another storage chassis was added. Now, space problem gone, fine, but what about speed? Three of the VDEVs are quite full, as indicated below. VDEV #3 (the one with the spare active) just spent some 72 hours resilvering a 2TB drive. Now, those green drives suck quite hard, but not

My current home fileserver (running Open Solaris 111b and ZFS) has an ASUS M2N-SLI DELUXE motherboard. This has 6 SATA connections, which are currently all in use (mirrored pair of 80GB for system zfs pool, two mirrors of 400GB both in my data pool). I''ve got two more hot-swap drive bays. And I''m getting up towards 90% full on the data pool. So, it''s time to expand,

Hi All, I believe this has been asked before, but I wasn?t able to find too much information about the subject. Long story short, I was moving data around on a storage zpool of mine and a zfs destroy <filesystem> hung (or so I thought). This pool had dedup turned on at times while imported as well; it?s running on a Nexenta Core 3.0.1 box (snv_134f). The first time the machine was

I skimmed the archives and found a thread from July earlier this year about RAIDZ expansion. Not adding more RAIDZ stripes to a pool, but adding more drives to the stripe itself. I''m wondering if an RFE has been submitted for this and if any progress has been made, or is expected? I find myself out of space on my current RAID5 setup and would love to flip over to a ZFS raidz2 solution

My setup: A SuperMicro 24-drive chassis with Intel dual-processor motherboard, three LSI SAS3081E controllers, and 24 SATA 2TB hard drives, divided into three pools with each pool a single eight-disk RAID-Z2. (Boot is an SSD connected to motherboard SATA.) This morning I got a cheerful email from my monitoring script: "Zchecker has discovered a problem on bigdawg." The full output is

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
