I''m seeing some pretty pitiful performance using ZFS on a NFS server, with a ZFS volume exported (only with rw=host.foo.com,root=host.foo.com opts) and mounted on a Linux host running kernel 2.4.31. This linux kernel I''m working with is limited in that I can only do NFSv2 mounts... irregardless of that aspect, I''m sure something''s amiss. I mounted the zfs-based

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 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.

Hello, I am trying to configure ZFS with IBM sdd. IBM sdd is like powerpath, MPXIO or VxDMP. Here is the error message when I try to create my pool: bash-3.00# zpool create tank /dev/dsk/vpath1a warning: device in use checking failed: No such device internal error: unexpected error 22 at line 446 of ../common/libzfs_pool.c bash-3.00# zpool create tank /dev/dsk/vpath1c cannot open

I have a system running in a VM with a root pool. The root pool occasionally shows a fairly stern warning. This warning comes with no check sum errors. bash-3.00# zpool status -vx pool: rpool 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

Yesterday morning I awoke to alerts from my SAN that one of my OS disks was faulty, FMA said it was in hardware failure. By the time I got to work (1.5 hours after the email) ALL of my pools were in a degraded state, and "tank" my primary pool had kicked in two hot spares because it was so discombobulated. ------------------- EMAIL ------------------- List of faulty resources:

Hi, to shorten the story, I describe the situation. I have 4 disks in a zfs/svm config: c2t9d0 9G c2t10d0 9G c2t11d0 18G c2t12d0 18G c2t11d0 is devided in two: selecting c2t11d0 [disk formatted] /dev/dsk/c2t11d0s0 is in use by zpool storedge. Please see zpool(1M). /dev/dsk/c2t11d0s1 is part of SVM volume stripe:d11. Please see metaclear(1M). /dev/dsk/c2t11d0s2 is in use by zpool storedge. Please

Hello, all I''m "playing" with ZDB again on another test system, the rpool being uncompressed with 512-byte sectors. Here''s some output that puzzles me (questions follow): # zdb -dddddddd -bbbbbb rpool/ROOT/nightly-2012-01-31 260050 ... 1e80000 L0 DVA[0]=<0:200972e00:20200> DVA[1]=<0:391820a00:200> [L0 ZFS plain file] fletcher4 uncompressed

Not an really good subject, I know but that''s kind of what happend. I''m trying to build an backup-solution server, Windows users using OSCAR (which uses rsync) to sync their files to an folder and when complete takes a snapshot. It has worked before but then I turned on the -R switch to rsync and when I then removed the folder with rm -rf it crashed. I didn''t save what

Hi, We have a number of 4200''s setup using a combination of an SVM 4 way mirror and a ZFS raidz stripe. Each disk (of 4) is divided up like this / 6GB UFS s0 Swap 8GB s1 /var 6GB UFS s3 Metadb 50MB UFS s4 /data 48GB ZFS s5 For SVM we do a 4 way mirror on /,swap, and /var So we have 3 SVM mirrors d0=root (sub mirrors d10, d20, d30, d40) d1=swap (sub mirrors d11, d21,d31,d41)

the os ''s / first is on mirror /dev/dsk/c1t0d0s0 and /dev/dsk/c1t1d0s0, and then created home_pool using mirror, here is the mirror information. pool: omp_pool state: ONLINE scrub: none requested config: NAME STATE READ WRITE CKSUM omp_pool ONLINE 0 0 0 mirror ONLINE 0 0 0 c1t3d0s0 ONLINE

I''ve installed Open Solaris 2009.06 on a machine with 5 identical 1TB wd green drives to create a ZFS nas. The intended install is one drive dedicated to the OS and the remaining 4 drives in a raidz1 configuration. The install is working fine, but creating the raidz1 pool and rebooting is causing the machine report "Cannot find active partition" upon reboot. Below is command

After multiple power outages caused by storms coming through, I can no longer access /dev/zvol/dsk/poolname, which are hold l2arc and slog devices in another pool I don''t think this is related, since I the pools are ofline pending access to the volumes. I tried running find /dev/zvol/dsk/poolname -type f and here is the stack, hopefully this someone a hint at what the issue is, I have

Hey, I am testing Glusterfs as a storage backend for dovecot as a LDA and imap server.

We are currently experiencing a very huge perfomance drop on our zfs storage server. We have 2 pools, pool 1 stor is a raidz out of 7 iscsi nodes, home is a local mirror pool. Recently we had some issues with one of the storagenodes, because of that the pool was degraded. Since we did not succeed in bringing this storagenode back online (on zfs level) we upgraded our nashead from opensolaris b57
