similar to: data error in dataset 0. what''s that?

Hi, I just had my Dell R610 reboot with a kernel panic when I threw a couple of zfs clone commands in the terminal at it. Now, after the system had rebooted zfs will not import my pool anylonger and instead the kernel will panic again. I have had the same symptom on my other host, for which this one is basically the backup, so this one is my last line if defense. I tried to run zdb -e

I have a huge problem with space maps on thumper. Space maps takes over 3GB and write operations generates massive read operations. Before every spa sync phase zfs reads space maps from disk. I decided to turn on compression for pool ( only for pool, not filesystems ) and it helps. Now space maps, intent log, spa history are compressed. Not I''m thinking about disabling checksums. All

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

Hi. I''m in the process of writing an introductory paper on ZFS. The paper is meant to be something that could be given to a systems admin at a site to introduce ZFS and document common procedures for using ZFS. In the paper, I want to document the method for identifying which file has a checksum error. In previous discussions on this alias, I''ve used the following

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I would like to know the blocksize of a particular file. I know the blocksize for a particular file is decided at creation time, in fuction of the write size done and the recordsize property of the dataset. How can I access that information?. Some zdb magic?. - -- Jesus Cea Avion _/_/ _/_/_/ _/_/_/ jcea at

Hi peoples, I have a Samba Server that has had the same config for over 10 months now (read: never had a problem). Just today, I thought, let's Play with Flash MX, so download I did. Start playing around, and went to test my first movie and it came up blank. Not a flash GURU that I am, I was stumped. Anyway. Saved the flash file to my local C:\ (Oh did I mention the WS is Win2k ;) .. and

I''ve got a CentOS 5.3 dom0 with Xen 3.4.1-rc5 (or so). I''ve tried the same stuff below with 3.4.0, no difference. I''m trying to install 2009.06 PV domU based on instructions from [1] and [2]. I can run the install fine, I can also get the kernel and boot archive (from [2]) after the install. But for the life of me I can''t get the installed domU to boot. If I

After a crash, in my zpool tree, some dataset report this we i do a ls -la: brwxrwxrwx 2 777 root 0, 0 Oct 18 2009 mail-cts also if i set zfs set mountpoint=legacy dataset and then i mount the dataset to other location before the directory tree was only : dataset - vdisk.raw The file was a backing device of a Xen VM, but i cannot access the directory structure of this dataset. However i

I have a 100gb SAN lun in a pool, been running ok for about 6 months. panicked the system this morning. system was running S10U2. In the course of troubleshooting I''ve installed the latest recommended bundle including kjp 118833-36 and zfs patch 124204-03 created as: zpool create zfspool01 /dev/dsk/emcpower0c zfs create zfspool01/nb60openv zfs set mountpoint=legacy zfspool01/nb60openv

Hello all, I have an oi_148a PC with a single root disk, and since recently it fails to boot - hangs after the copyright message whenever I use any of my GRUB menu options. Booting with an oi_148a LiveUSB I had around since installation, I ran some zdb traversals over the rpool and zpool import attempts. The imports fail by running the kernel out of RAM (as recently discussed in the list with

Hi I know some of this has been discussed in the past but I can''t quite find the exact information I''m seeking (and I''d check the ZFS wikis but the websites are down at the moment). Firstly, which is correct, free space shown by "zfs list" or by "zpool iostat" ? zfs list: used 50.3 TB, free 13.7 TB, total = 64 TB, free = 21.4% zpool iostat: used

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

Hello all, I have a question about what output "ZDB -dddddd" should produce in L0 DVA fields. I expected there to be one or more same-sized references to data blocks stored in top-level vdevs (one vdev #0 in my 6-disk raidz2 pool), as confirmed by the source: http://src.illumos.org/source/xref/illumos-gate/usr/src/cmd/zdb/zdb.c#sprintf_blkptr_compact And I do see that for some of my

Formerly, if you interrupted a zfs receive, it would leave a clone with a % in its name, and you could find it via "zdb -d" and then you could destroy the clone, and then you could destroy the filesystem you had interrupted receiving. That was considered a bug, and it was fixed, I think by Sun. If the lingering clone was discovered laying around, zfs would automatically destroy it.

I sent a zvol from host a, to host b, twice. Host b has two pools, one ashift=9, one ashift=12. I sent the zvol to each of the pools on b. The original source pool is ashift=9, and an old revision (2009_06 because it''s still running xen). I sent it twice, because something strange happened on the first send, to the ashift=12 pool. "zfs list -o space" showed figures at

Not sure what the best list to send this to is right now, so I have selected a few, apologies in advance. A couple questions. First I have a physical host (call him bob) that was just installed with b134 a few days ago. I upgraded to b145 using the instructions on the Illumos wiki yesterday. The pool has been upgraded (27) and the zfs file systems have been upgraded (5). chris at bob:~# zpool

Hi List, First of all: S10u4 120011-14 So I have the weird situation. Earlier this week, I finally mirrored up two iSCSI based pools. I had been wanting to do this for some time, because the availability of the data in these pools is important. One pool mirrored just fine, but the other pool is another story. First lesson (I think) is you should scrub your pools, at least those backed by

Hi, I was wondering if anyone would know if this is just an accounting-type error with the recorded "version=" stored on disk, or if there are/could-be any deeper issues with an "upgraded" zpool? I created a pool under a Sol10_x86_u3 install (11/06?), and zdb correctly reported the pool as a "version=3" pool. I reinstalled the OS with a u4 (08/07), ran zpool
