I hope it works for you. If you have any reservations, please wait for Sun
to release something official, and don''t blame me if your data is gone.

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 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

multiple disk failure
Hi,
I am using FreeBSD 8.2 and went to add 4 new disks today to expand my
offsite storage. All was working fine for about 20min and then the new
drive cage started to fail. Silly me for assuming new hardware would be
fine :(
The new drive cage started to fail, it hung the server and the box
rebooted. After it rebooted, the entire pool is gone and in the state
below. I had only written a few

I had the rpool with two sata disks in the miror. Solaris 10 5.10

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

Hello,
I''ve been using Nexentastore Community Edition with no issues now for a
while now, however last week I was going to rebuild a different system so I
started to copy all the data off that to my to a raidz2 volume on me CE
system. This was going fine until I noticed that they copy was stalled, as
well as the entire system was non-responsive. I let it sit for several hours

10.0-BETA4 (upgraded from 9.2-RELEASE) zpool upgrade -> boot failure
Hi,
Is there anything known about ZFS under 10.0-BETA4 when FreeBSD was
upgraded from 9.2-RELEASE?
I have two servers, with very different hardware (on is with soft raid
and the other have not) and after a zpool upgrade, no way to get the
server booting.
Do I miss something when upgrading?
I cannot get the error message for the moment. I reinstalled the raid
server under Linux and the other

ZFS 60 second pause times to read 1K
Every day we see pause times of sometime 60 seconds to read 1K of a file for local reads as well as NFS in a test setup.
We have a x4500 setup as a single 4*( raid2z 9 + 2)+2 spare pool and have the files system mounted over v5 krb5 NFS and accessed directly. The pool is a 20TB pool and is using . There are three filesystems, backup, test and home. Test has about 20 million files and uses 4TB.

X4500 device disconnect problem persists
After applying 125205-07 on two X4500 machines running Sol10U4 and
removing "set sata:sata_func_enable = 0x5" from /etc/system to
re-enable NCQ, I am again observing drive disconnect error messages.

confused about zpool import -f and export
Hi, all,
I think I''m missing a concept with import and export. I''m working on installing a Nexenta b134 system under Xen, and I have to run the installer under hvm mode, then I''m trying to get it back up under pv mode. In that process the controller names change, and that''s where I''m getting tripped up.
I do a successful install, then I boot OK,

What happens when unmirrored ZIL log device is removed ungracefully
Due to recent experiences, and discussion on this list, my colleague and I
performed some tests:
Using solaris 10, fully upgraded. (zpool 15 is latest, which does not have
log device removal that was introduced in zpool 19) In any way possible,
you lose an unmirrored log device, and the OS will crash, and the whole
zpool is permanently gone, even after reboots.
Using opensolaris,

zpool import panics
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

zfs drive keeps failing between export and import
I have a zpool that consists for a two-drive mirror. The two times I
took the zpool offline, I had to resilver one of the drives (the same
drive both times) when I imported it back. All drives in the pool
show no read, write, or checksum errors and are new, so I'm looking to
a software problem before hardware. Both drives are encrypted geli
devices. I tried to reproduce the error with 1GB

zpool upgrade and zfs upgrade behavior on b145
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).

Resliver making the system unresponsive
This must be resliver day :)
I just had a drive failure. The hot spare kicked in, and access to the pool over NFS was effectively zero for about 45 minutes. Currently the pool is still reslivering, but for some reason I can access the file system now.
Resliver speed has been beaten to death I know, but is there a way to avoid this? For example, is more enterprisy hardware less susceptible to
