(gang?)block layout question, and how to decipher ZDB output?
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

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.

Recovering from kernel panic / reboot cycle importing pool.
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:

Finding where dedup''d files are
Is there an easy way to find out what datasets have dedup''d data in them. Even better would be to discover which files in a particular dataset are dedup''d. I ran # zdb -DDDD which gave output like: index 1055c9f21af63 refcnt 2 single DVA[0]=<0:1e274ec3000:2ac00:STD:1> [L0 deduplicated block] sha256 uncompressed LE contiguous unique unencrypted 1-copy size=20000L/20000P

Single-disk rpool with inconsistent checksums, import fails
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

tracking an error back to a file
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

Need Help Invalidating Uberblock
I have a ZFS pool that has been corrupted. The pool contains a single device which was actually a file on UFS. The machine was accidentally halted and now the pool is corrupt. There are (of course) no backups and I''ve been asked to recover the pool. The system panics when trying to do anything with the pool. root@:/$ zpool status panic[cpu1]/thread=fffffe8000758c80: assertion failed:

Inconcistancies with scrub and zdb
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

Pool performance when nearly full
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

zdb assertion failure/zpool recovery
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi, I have a corrupt pool, which lives on a .vdi file of a VirtualBox. IIRC the corruption (i.e. pool being not importable) was caused when I killed virtual box, because it was hung. This pool consists of a single vdev and I would really like to get some files out of that thing. So I tried running zdb, but this fails with an assertion failure:

reproducible zfs panic on Solaris 10 06/06
Hi, I am able to reproduce the following panic on a number of Solaris 10 06/06 boxes (Sun Blade 150, V210 and T2000).

Major problem with a new ZFS setup
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

ZFS panics solaris while switching a volume to read-only
Hi, I just found out that ZFS triggers a kernel-panic while switching a mounted volume into read-only mode: The system is attached to a Symmetrix, all zfs-io goes through Powerpath: I ran some io-intensive stuff on /tank/foo and switched the device into read-only mode at the same time (symrdf -g bar failover -establish). ZFS went ''bam'' and triggered a Panic: WARNING: /pci at

zfs corruption...
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
