Now that Solaris 10 11/06 is available, I wanted to post the complete list of ZFS features and bug fixes that were included in that release. I''m also including the necessary patches for anyone wanting to get all the ZFS features and fixes via patches (NOTE: later patch revision may already be available): Solaris 10 Update 3 (11/06) Patches sparc Patches * 118833-36 SunOS 5.10:

I was doing some disaster recovery testing with ZFS, where I did a mass backup of a family of ZFS filesystems using snapshots, destroyed them, and then did a mass restore from the backups. The ZFS filesystems I was testing with had only one parent in the ZFS namespace; and the backup and restore went well until it came time to mount the restored ZFS filesystems. Because I had destroyed

Hi all, It would appear that I have a zpool corruption issue to deal with... pool is exported, but upon trying to import it, server panics.  Are there any tools available on a zpool that is in an exported state?  I''ve got a separate test bed in which I''m trying to recreate, but I keep getting messages to the effect of need to import the pool first.  Suggestions? thanks Jay

We''re planning to build a ZFS-based Solaris NFS fileserver environment with the backend storage being iSCSI-based, in part because of the possibilities for failover. In exploring things in our test environment, I have noticed that ''zpool import'' takes a fairly long time; about 35 to 45 seconds per pool. A pool import time this slow obviously has implications for how fast

Hello We have an ocfs2 1.6 via drbd dual master. drbd0 -> sda7 (node1) drbd0 -> sda7 (node2) ocfs2 1.6 2.6.38-2-amd64 kernel panic when unmount. when unmount drbd0 on both node around the same time using dsh. umount -v /dev/drbd0 the umount process hangs for a while, 30mins or so pts/0 D+ 20:50 0:00 umount /dev/drbd0 -vvvvv Then, one of the node kernel panics Message from

Anyone have any idea on this. I wanted to separate out my VirtualBox VDIs so that I could activate compression on the rest of the parent directory structure so I created a ZFS filesystem under my user directory. mv .VirtualBox .VirtualBox_orig zfs create /export/home/user/.VirtualBox zfs create /export/home/user/.VirtualBox/VDI zfs set compression=off /export/home/user/.VirtualBox/VDI zfs set

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

Hi All, How do I unmount an NFS share when the NFS server is unaivalable? I tried "umount /bck" but it "hangs" indefinitely "umount -f /bck" tells me the mount if busy and I can't unmount it: root at saturn:[~]$ umount -f /bck umount2: Device or resource busy umount: /bck: device is busy umount2: Device or resource busy umount: /bck: device is busy This

New server build with Solaris-10 u5/08, on a SunFire t5220, and this is our first rollout of ZFS and Zpools. Have 8 disks, boot disk is hardware mirrored (c1t0d0 + c1t1d0) Created Zpool my_pool as RaidZ using 5 disks + 1 spare: c1t2d0, c1t3d0, c1t4d0, c1t5d0, c1t6d0, and spare c1t7d0 I am working on alerting & recovery plans for disks failures in the zpool. As a test, I have pulled disk

Hi, Can anyone explain the following to me? Two zpool devices points at the same data, I was installing osol 2008.11 in xVM when I saw that there already was a partition on the installation disk. An old dataset that I deleted since i gave it a slightly different name than I intended is not removed under /dev. I should not have used that name, but two device links should perhaps not

Chapter 9, "Troubleshooting and Data Recovery", p.115 states: "To enable background scrubbing, use the zpool set command: # zpool set scrub=2w The parameter is a time duration indicating how often a complete scrub should be performed. In this case, the administrator is requesting that the pool be scrubbed once every two weeks. ZFS automatically tries to schedule I/O to even

Hello, I've noticed a strange delay while booting a CentOS 7 guest on a CentOS 7 host with slow disks (7200RPM) with write cache off. The guest and host are freshly installed Centos 7 (host was fully patched before guest install). Guest is installed on an lvm pool residing on an md raid1 with two SATA 7200 RPM drives with their write caches off. The delay is on mounting /boot, the dmesg

Hi, I had a hot spare used to replace a failed drive, but then the drive appears to be fine anyway.

Hi, since hostid is stored in the label, "zpool import" failed if the hostid dind''t match. Under certain circonstances (ldom failover) it means you have to manually force the zpool import while booting. With more than 80 LDOMs on a single host it will be great if we could configure the machine back to the old behavior where it didn''t failed, maybe with a /etc/sytem

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
