libzfs zfs_create() fails on sun4u daily bits (daily.1110)
I encountered a strange libzfs behavior while testing a zone fix and want to make sure that I found a genuine bug. I''m creating zones whose zonepaths reside in ZFS datasets (i.e., the parent directories of the zones'' zonepaths are ZFS datasets). In this scenario, zoneadm(1M) attempts to create ZFS datasets for zonepaths. zoneadm(1M) has done this for a long time (since

files lost in the zpool - retrieval possible ?
Greetings, my Opensolaris 06/2009 installation on an Thinkpad x60 notebook is a little unstable. From the symptoms during installation it seems that there might be something with the ahci driver. No problem with the Opensolaris LiveCD system. Some weeks ago during copy of about 2 GB from a USB stick to the zfs filesystem, the system froze and afterwards refused to boot. Now when investigating

zfs list extentions related to pNFS
Hi, I am soliciting input from the ZFS engineers and/or ZFS users on an extension to "zfs list". Thanks in advance for your feedback. Quick Background: The pNFS project (http://opensolaris.org/os/project/nfsv41/) is adding a new DMU object set type which is used on the pNFS data server to store pNFS stripe DMU objects. A pNFS dataset gets created with the "zfs

recursive snaptshot
I thought I recalled reading somewhere that in the situation where you have several zfs filesystems under one top level directory like this: rpool rpool/ROOT/osol-112 rpool/export rpool/export/home rpool/export/home/reader you could do a shapshot encompassing everything below zpool instead of having to do it at each level. (Maybe it was in a dream...)

Doing ZFS rollback with preserving later created clones/snapshot?
Hi. Is it possible on Solaris 10 5/09, to rollback to a ZFS snapshot, WITHOUT destroying later created clones or snapshots? Example: --($ ~)-- sudo zfs snapshot rpool/ROOT at 01 --($ ~)-- sudo zfs snapshot rpool/ROOT at 02 --($ ~)-- sudo zfs clone rpool/ROOT at 02 rpool/ROOT-02 --($ ~)-- LC_ALL=C sudo zfs rollback rpool/ROOT at 01 cannot rollback to ''rpool/ROOT at 01'': more

sub-optimal ZFS performance
Hello, ZFS is behaving strange on a OSOL laptop, your thoughts are welcome. I am running OSOL on my laptop, currently b124 and i found that the performance of ZFS is not optimal in all situations. If i check the how much space the package cache for pkg(1) uses, it takes a bit longer on this host than on comparable machine to which i transferred all the data. user at host:/var/pkg$ time

How to rename rpool. Is that recommended ?
Hello, I have a situation where a host, which is booted off its ''rpool'', need to temporarily import the ''rpool'' of another host, edit some files in it, and export the pool back retaining its original name ''rpool''. Can this be done ? Here is what I am trying to do: # zpool import -R /a rpool temp-rpool # zfs set mountpoint=/mnt

virsh troubling zfs!?
Hi and hello, I have a problem confusing me. I hope someone can help me with it. I followed a "best practise" - I think - using dedicated zfs filesystems for my virtual machines. Commands (for completion): [i]zfs create rpool/vms[/i] [i]zfs create rpool/vms/vm1[/i] [i] zfs create -V 10G rpool/vms/vm1/vm1-dsk[/i] This command creates the file system [i]/rpool/vms/vm1/vm1-dsk[/i] and the

Problems mounting ZFS after install
Let me thank everyone in advance. I''ve read a number of posts here and it helped tremendously in getting the install done. I have a couple of remaining issues which I can''t seem to overcome.

SUMMARY: mounting datasets from a read-only pool with aid of tmpfs
Hello all, I''d like to report a tricky situation and a workaround I''ve found useful - hope this helps someone in similar situations. To cut the long story short, I could not properly mount some datasets from a readonly pool, which had a non-"legacy" mountpoint attribute value set, but the mountpoint was not available (directory absent or not empty). In this case

ZFS import on pool with same name?
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

Problem w/ b95 + ZFS (version 11) - seeing fair number of errors on multiple machines
Hi, After upgrading to b95 of OSOL/Indiana, and doing a ZFS upgrade to the newer revision, all arrays I have using ZFS mirroring are displaying errors. This started happening immediately after ZFS upgrades. Here is an example: ormandj at neutron.corenode.com:~$ zpool status pool: rpool state: DEGRADED status: One or more devices has experienced an unrecoverable error. An attempt was

What''s eating my disk space? Missing snapshots?
Please can someone take a look at the attached file which shows the output on my machine of zfs list -r -t filesystem,snapshot -o space rpool/export/home/matt The USEDDS figure of ~2GB is what I would expect, and is the same figure reported by the Disk Usage Analyzer. Where is the remaining 13.8GB USEDSNAP figure coming from? If I total up the list of zfs-auto snapshots it adds up to about 4.8GB,

rpool recover not using zfs send/receive
Is it possible to recover the rpool with only a tar/star archive of the root filesystem? I have used the zfs send/receive methods and that work without a problem. What I am trying to do is recreate the rpool and underlying zfs filesystems (rpool/ROOT, rpool/s10_uXXXXXX, rpool/dump, rpool/swap, rpool/export, and rpool/export/home). I then mount the pool at a alternate root and restore the tar

zfs allow does not work for rpool
I am trying to give a general user permissions to create zfs filesystems in the rpool. zpool set=delegation=on rpool zfs allow <user> create rpool both run without any issues. zfs allow rpool reports the user does have create permissions. zfs create rpool/test cannot create rpool/test : permission denied. Can you not allow to the rpool? -- This message posted from opensolaris.org

Best practice for full stystem backup - equivelent of ufsdump/ufsrestore
I''m looking for a way to backup my entire system, the rpool zfs pool to an external HDD so that it can be recovered in full if the internal HDD fails. Previously with Solaris 10 using UFS I would use ufsdump and ufsrestore, which worked so well, I was very confident with it. Now ZFS doesn''t have an exact replacement of this so I need to find a best practice to replace it.

"no pool_props" for OpenSolaris 2009.06 with old SPARC hardware
Hi, yesterday evening I tried to upgrade my Ultra 60 to 2009.06 from SXCE snv_98. I can''t use AI Installer because OpenPROM is version 3.27. So I built IPS from source, then created a zpool on a spare drive and installed OS 2006.06 on it To make the disk bootable I used: installboot -F zfs /usr/platform/`uname -i`/lib/fs/zfs/bootblk /dev/rdsk/c0t1d0s0 using the executable from my new

time-sliderd doesn''t remove snapshots
In the last few days my performance has gone to hell. I''m running: # uname -a SunOS nissan 5.11 snv_150 i86pc i386 i86pc (I''ll upgrade as soon as the desktop hang bug is fixed.) The performance problems seem to be due to excessive I/O on the main disk/pool. The only things I''ve changed recently is that I''ve created and destroyed a snapshot, and I used

zpool import -f rpool hangs
I had the rpool with two sata disks in the miror. Solaris 10 5.10 Generic_141415-08 i86pc i386 i86pc Unfortunately the first disk with grub loader has failed with unrecoverable block write/read errors. Now I have the problem to import rpool after the first disk has failed. So I decided to do: "zpool import -f rpool" only with second disk, but it''s hangs and the system is
