similar to: ZFS Replication Question

Hello SUN gurus I do not know if this is supported, I have a created a zpool consisting of the SAN resources and created a zfs file system. Using third part software I have taken snapshots of all luns in the zfs pool. My question is in a recovery situation is there a way for me to mount the snapshots and import the pool while the original is still active. Right now all I am able to do is export

Hi, I''m struggling to get a stable ZFS replication using Solaris 10 110/06 (actual patches) and AVS 4.0 for several weeks now. We tried it on VMware first and ended up in kernel panics en masse (yes, we read Jim Dunham''s blog articles :-). Now we try on the real thing, two X4500 servers. Well, I have no trouble replicating our kernel panics there, too ... but I think I

So I just imported an old zpool onto this new system. The problem would be one drive (c4d0) is showing up twice. First it''s displayed as ONLINE, then it''s displayed as "UNAVAIL". This is obviously causing a problem as the zpool now thinks it''s in a degraded state, even though all drives are there, and all are online. This pool should have 7 drives total,

Hi, yesterday I implemented a simple hourly snapshot on my filesystems. I also regularly initiate a manual "zpool scrub" on all my pools. Usually the scrubbing will run for about 3 hours. But after enabling hourly snapshots I noticed that zfs scrub is always restarted if a new snapshot is created - so basically it will never have the chance to finish: # zpool scrub scratch # zpool

Good morning, I have a problem with ZFS: ZFS filesystem version 4 ZFS storage pool version 15 Yesterday my comp with Freebsd 8.2 releng shutdown with ad4 error detached,when I copy a big file... and after reboot in 2 wd green 1tb say me goodbye. One of them die and other with zfs errors: Apr 24 04:53:41 Flash root: ZFS: vdev I/O failure, zpool=zroot path= offset=187921768448 size=512 error=6

If it''s of interest, I''ve written up some articles on my experiences of building a ZFS NAS box which you can read here: http://breden.org.uk/2008/03/02/a-home-fileserver-using-zfs/ I used CIFS to share the filesystems, but it will be a simple matter to use NFS instead: issue the command ''zfs set sharenfs=on pool/filesystem'' instead of ''zfs set

Hi. I''d like to request a feature be added to zfs. Currently, on SAN attached disk, zpool shows up with a big WWN for the disk. If ZFS (or the zpool command, in particular) had a text field for arbitrary information, it would be possible to add something that would indicate what LUN on what array the disk in question might be. This would make troubleshooting and general

Hi, Is it possible to convert a zfs pool from a concatenation of 2 disks to a 2 way mirror without backing up the data, re-creating the pool and restoring it. i.e diskA,diskB ----> mirror(diskA,diskB) Thanks, Jeff

I have an OpenSolaris snv_101 box with ZFS on it. (Sun Ultra 20 M2) zpool name is rpool. The I have a 2nd hard drive in the box that I am trying to recover the ZFS data from (long story but that HD became unbootable after installing IPS on the machine) Both drives have a pool named "rpool", so I can''t import the rpool from the 2nd drive. root at hyperion:~# zpool status

We have a Mirror setup in ZFS that''s 73GB (two internal disks on a sun fire v440). We currently are going to attach this system to an Equallogic Box, and will attach an ISCSCI LUN from the Equallogic box to the v440 of about 200gb. The Equallogic Box is configured as a Hardware Raid 50 (two hot spares for redundancy). My question is what''s the best approach to moving the ZFS

We recently installed a 24 disk SATA array with an LSI controller attached to a box running Solaris X86 10 Release 4. The drives were set up in one big pool with raidz, and it worked great for about a month. On the 4th, we had the system kernel panic and crash, and it''s now behaving very badly. Here''s what diagnostic data I''ve been able to collect so far: In the

Hi, I have two servers running: freebsd with a zpool v28 and a nexenta (opensolaris b134) running zpool v26. Replication (with zfs send/receive) from the nexenta box to the freebsd works fine, but I have a problem accessing my replicated volume. When I''m typing and autocomplete with tab key the command cd /remotepool/us (for /remotepool/users) I get a panic. check the panic @

ZFS documentation lists snapshot limits on any single file system in a pool at 2**48 snaps, and that seems to logically imply that a snap on a file system does not require an update to the pool?s currently active uberblock. That is to say, that if we take a snapshot of a file system in a pool, and then make any changes to that file system, the copy on write behavior induced by the changes will

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

We have some HDS storage that isn''t supported by mpxio, so we have to use veritas dmp to get multipathing. Whats the recommended way to use DMP storage with ZFS. I want to use DMP but get at the multipathed virtual luns at as low a level as possible to avoid using vxvm as much as possible. I figure theres no point in having overhead from 2 volume manages if we can avoid it. Has anyone

I posted this on the www.nexentastor.org forums, but no answer so far, so I apologize if you are seeing this twice. I am also engaged with nexenta support, but was hoping to get some additional insights here. I am running nexenta 3.0.3 community edition, based on 134. The box crashed yesterday, and goes into a reboot loop (kernel panic) when trying to import my data pool, screenshot attached.

(for some reason I cannot find my original thread..so I''m reposting it) I am trying to move my data off of a 40gb 3.5" drive to a 40gb 2.5" drive. This is in a Netra running Solaris 10. Originally what I did was: zpool attach -f rpool c0t0d0 c0t2d0. Then I did an installboot on c0t2d0s0. Didnt work. I was not able to boot from my second drive (c0t2d0). I cannot remember

Hi there, i''m building a small NAS with 5x1TB Disks. The disks contains at the moment some data, ntfs as the fs and aren''t a raid. Now my im wondering if its possible to add the parity later. So that i add step by step one disk to the pool. And when i add the last disk, i enable the parity. (i have only one another 1 tb disk to backup the files) Thank you for you replies and

OK, I''ve been putting off this question for a while now, but it eating at me, so I can''t hold off any more. I have a nice 8 gig memory stick I''ve formated with the ZFS file system. Works great on all my Solaris PC''s, but refuses to work on my Sparc processor. So I''ve formated it on my Sparc machine (Blade 2500), works great there now, but not on
