similar to: vanished ZFS pool

Hi All, I posted this in a different threat, but it was recommended that I post in this one. Basically, I have a 3 drive raidz array on internal Seagate drives. running build 64nv. I purchased 3 add''l USB drives with the intention of mirroring and then migrating the data to the new USB drives. I accidentally added the 3 USB drives in a raidz to my original storage pool, so now I have 2

Hello list, I posted this a few days ago on opensolaris-discuss@ list I am posting here, because there my be too much noise on other lists I have been without this zfs set for a week now. My main concern at this point,is it even possible to recover this zpool. How does the metadata work? what tool could is use to rebuild the corrupted parts or even find out what parts are corrupted. most but

I''m seeing odd behaviour when I create a ZFS raidz pool using three disks. The output of "zpool status" shows the pool size as the size of the three disks combined (as if it were a Raid 0 volume). This isn''t expected behaviour is it? When I create a mirrored volume in ZFS everything is as one would expect the pool is the size of a single drive. My setup: Compaq

On a system still running nv_30, I''ve a small RaidZ filled to the brim: 2 3 root at mir pts/9 ~ 78# uname -a SunOS mir 5.11 snv_30 sun4u sparc SUNW,UltraAX-MP 0 3 root at mir pts/9 ~ 50# zfs list NAME USED AVAIL REFER MOUNTPOINT mirpool1 33.6G 0 137K /mirpool1 mirpool1/home 12.3G 0 12.3G /export/home mirpool1/install 12.9G

I made a bad judgment and now my raidz pool is corrupted. I have a raidz pool running on Opensolaris b85. I wanted to try out freenas 0.7 and tried to add my pool to freenas. After adding the zfs disk, vdev and pool. I decided to back out and went back to opensolaris. Now my raidz pool will not mount and got the following errors. Hope someone expert can help me recover from this error.

I have a question about using mixed vdev in the same zpool and what the community opinion is on the matter. Here is my setup: I have four 1TB drives and two 500GB drives. When I first setup ZFS I was under the assumption that it does not really care much on how you add devices to the pool and it assumes you are thinking things through. But when I tried to create a pool (called group) with four

Hi, I am using FreeBSD 8.2 and went to add 4 new disks today to expand my offsite storage. All was working fine for about 20min and then the new drive cage started to fail. Silly me for assuming new hardware would be fine :( The new drive cage started to fail, it hung the server and the box rebooted. After it rebooted, the entire pool is gone and in the state below. I had only written a few

I seem to have managed to end up with a pool that is confused abut its children disks. The pool is faulted with corrupt metadata: pool: d state: FAULTED status: The pool metadata is corrupted and the pool cannot be opened. action: Destroy and re-create the pool from a backup source. see: http://illumos.org/msg/ZFS-8000-72 scan: none requested config: NAME STATE

In my testing, I''ve found the following error: zpool status -v pool: local 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 the entire pool from backup. see: http://www.sun.com/msg/ZFS-8000-8A scrub: none requested

I would like to pick the brains of the ZFS experts on this list: What would you do next to try and recover this zfs pool? I have a ZFS RAIDZ1 pool named bank0 that I cannot import. It was composed of 4 1.5 TiB disks. One disk is totally dead. Another had SMART errors, but using GNU ddrescue I was able to copy all the data off successfully. I have copied all 3 remaining disks as images using

I have two identical Supermicro boxes with 32GB ram. Hardware details at the end of the message. They were running OI 151.a.5 for months. The zpool configuration was one storage zpool with 3 vdevs of 8 disks in RAIDZ2. The OI installation is absolutely clean. Just next-next-next until done. All I do is configure the network after install. I don''t install or enable any other services.

I managed to create a link in a ZFS directory that I can''t remove. Session as follows: # ls bayes.lock.router.3981 bayes_journal user_prefs # ls -li bayes.lock.router.3981 bayes.lock.router.3981: No such file or directory # ls bayes.lock.router.3981 bayes_journal user_prefs # /usr/sbin/unlink bayes.lock.router.3981 unlink: No such file or directory # find . -print

Hi, I had a plan to set up a zfs pool with different raid levels but I ran into an issue based on some testing I''ve done in a VM. I have 3x 750 GB hard drives and 2x 320 GB hard drives available, and I want to set up a RAIDZ for the 750 GB and mirror for the 320 GB and add it all to the same pool. I tested detaching a drive and it seems to seriously mess up the entire pool and I

Long story short, my cat jumped on my server at my house crashing two drives at the same time. It was a 7 drive raidz (next time ill do raidz2). The server crashed complaining about a drive failure, so i rebooted into single user mode not realizing that two drives failed. I put in a new 500g replacement and had zfs start a replace operation which failed at about 2% because there was two broken

Hi, I have setup an old Compaq Proliant DL580 with 2 xeon @700MHz 2Gb RAM two SmartArray 5300 controllers and 12 drives in an array enclosure. I am running the latest opensolaris update bfu''ed from binaries since I could not build from source. I am controlling the drives with the cpqary3 driver (Solaris 10) from HP. Initially the array had 7 drives and I created a raidz zfs pool

Hello, I have been asked to take a look at at poll on a old OSOL 2009.06 host. It have been left unattended for a long time and it was found in a FAULTED state. Two of the disks in the raildz2 pool seems to have failed, one have been replaced by a spare, the other one is UNAVAIL. The machine was restarted and the damaged disks was removed to make it possible to access the pool without it hanging

<http://www.solarisinternals.com/wiki/index.php/ZFS_Best_Practices_Guide#RAID-Z_Configuration_Requirements_and_Recommendations> says that the number of disks in a RAIDZ should be (N+P) with N = {2,4,8} and P = {1,2}. But if you go down the page just a little further to the thumper configuration examples, none of the 3 examples follow this recommendation! I will have 10 disks to put into a

Folks, >From zfs documentation, it appears that a "vdev" can be built from more vdevs. That is, a raidz vdev can be built across a bunch of mirrored vdevs, and a mirror can be built across a few raidz vdevs. Is my understanding correct? Also, is there a limit on the depth of a vdev? Thank you in advance for your help. Regards, Peter -- This message posted from opensolaris.org

Hi all, I recently created a RAID-Z1 pool out of a set of 7 SCSI disks, using the following command: # zpool create magicant raidz c5t0d0 c5t1d0 c5t2d0 c5t3d0 c5t4d0 c5t5d0 c5t6d0 It worked fine, but I was slightly confused by the size yield (99 GB vs the 116 GB I had on my other RAID-Z1 pool of same-sized disks). I thought one of the disks might have been to blame, so I tried swapping it out
