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

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:

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

ZFS Recovery: What do I try next?
I would like to pick the brains of the ZFS experts on this list: What
would you do next to try and recover this zfs pool?
I have a ZFS RAIDZ1 pool named bank0 that I cannot import. It was
composed of 4 1.5 TiB disks. One disk is totally dead. Another had
SMART errors, but using GNU ddrescue I was able to copy all the data
off successfully.
I have copied all 3 remaining disks as images using

(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.

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.

ZDB returning strange values
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:

Using same ZFS under different kernel versions
I build two zfs filesystems using b29 (from brandz).
I then re-installed solaris express b28, preserving the zfs filesystems.
When I tried to "zpool import" my zfs filesystems I got a kernel panic:

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.

Checksum fletcher4 or sha256 ?
Hi,
I''m atmost ready to deploy my new homeserver for final testing.
Before I want to be sure that nothing big is left untouched.
Reading ZFS Admin Guide About the checksum method, there''s no advice about it.
The default is fletcher4. there''s also SHA256
Now the sha256 is pretty ''heavy'' to calculate, so I think that it''s left out because can

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

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.

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.

which gave output like:
