sharing a ssd between rpool and l2arc
Hi,
as Richard Elling wrote earlier:
"For more background, low-cost SSDs intended for the boot market are
perfect candidates. Take a X-25V @ 40GB and use 15-20 GB for root
and the rest for an L2ARC. For small form factor machines or machines
with max capacity of 8GB of RAM (a typical home system) this can make a
pleasant improvement over a HDD-only implementation."

Adding a higher level partition to ZFS pool
Hi all,
I would like to add a new partition to my ZFS pool but it looks like it''s more stricky than expected.
The layout of my disk is the following:
- first partition for Windows. I want to keep it. (no formatting !)
- second partition for OpenSolaris.This is where I have all the Solaris slices (c0d0s0 etc). I have a single ZFS pool. OpenSolaris boots on ZFS.
- third partition: a FAT

ZFS Pool Question
Hello, I''m looking for info on adding a disk to my current zfs pool. I am running OpenSoarlis snv_98. I have upgraded my pool since my image-update. When I installed OpenSolaris it was a machine with 2 hard disks (regular IDE). Is it possible to add the second hard disk to the pool to increase my storage capacity without a raid controller?

Expanding a root pool
I''m attempting to expand a root pool for a VMware VM that is on an 8GB virtual disk. I mirrored it to a 20GB disk and detached the 8GB disk. I did "installgrub" to install grub onto the second virtual disk, but I get a kernel panic when booting. Is there an extra step I need to perform to get this working?
Basically I did this:
1. Created a new 20GB virtual disk.
2. Booted

Moving a pool from FreeBSD 8.0 to opensolaris
I was wondering what the best method of moving a pool from FreeBSD 8.0 to
OpenSolaris is.
When i originally built my system, it was using hardware which wouldn''t work
in opensolairs, but i''m about to do an upgrade so i should be able to use
Opensolaris when i''m done.
My current system uses a Highpoint RocketRaid 2340. It has 12 1TB hard

Single-disk pool corrupted after controller failure
I had a single spare 500GB HDD and I decided to install a FreeBSD file
server in it for learning purposes, and I moved almost all of my data
to it. Yesterday, and naturally after no longer having backups of the
data in the server, I had a controller failure (SiS 180 (oh, the
quality)) and the HDD was considered unplugged. When I noticed a few
checksum failures on `zfs status` (including two on

mounting a copy of a zfs pool /file system while orginal is still active
Hello SUN gurus I do not know if this is supported, I have a created a zpool consisting of the SAN resources and created a zfs file system. Using third part software I have taken snapshots of all luns in the zfs pool. My question is in a recovery situation is there a way for me to mount the snapshots and import the pool while the original is still active. Right now all I am able to do is export

can you recover a pool if you lose the zil (b134+)
I was messing around with a ramdisk on a pool and I forgot to remove it
before I shut down the server. Now I am not able to mount the pool. I am
not concerned with the data in this pool, but I would like to try to figure
out how to recover it.
I am running Nexenta 3.0 NCP (b134+).
I have tried a couple of the commands (zpool import -f and zpool import -FX

one ZIL SLOG per zpool?
I have three zpools on a server and want to add a mirrored pair of ssd''s for the ZIL. Can the same pair of SSDs be used for the ZIL of all three zpools or is it one ZIL SLOG device per zpool?

How do I get my pool back?
After having to replace an internal raid card in an X2200 (S10U3 in
this case), I can see the disks just fine - and can boot, so the data
isn''t completely missing.
However, my zpool has gone.

restore lost pool after vtoc re-label
hi all,
i''ve been using a SAN LUN as the sole member of a zpool with one additional zfs filesystem. this is a flat SAN fabric, so this LUN was available to other systems on the fabric, and one of them came up with "wrong magic number" for several drives, and, as best i can tell, the vtoc for my zpool LUN was over-written on that host via format labeling to correct the error.

convert raidz from osx
I am converting a 4 disk raidz from osx to opensolaris. And I want to keep the data intact.
I want zfs to get access to the full disk instead of a slice.
I believe like c8d0 instead off c8d0s1.
I wanted to do this 1 disk at a time and let it resilver.
what is the proper way to do this.
I tried, I believe from memory : zpool replace -f rpool c8d1s1 c8d1
but it didn''t let me do that.

Help replacing dual identity disk in ZFS raidz and SVM mirror
Hi,
We have a number of 4200''s setup using a combination of an SVM 4 way mirror and a ZFS raidz stripe.
Each disk (of 4) is divided up like this
/ 6GB UFS s0
Swap 8GB s1
/var 6GB UFS s3
Metadb 50MB UFS s4
/data 48GB ZFS s5
For SVM we do a 4 way mirror on /,swap, and /var
So we have 3 SVM mirrors
d0=root (sub mirrors d10, d20, d30, d40)
d1=swap (sub mirrors d11, d21,d31,d41)

Poor man''s backup by attaching/detaching mirror drives on a _striped_ pool?
Hi,
one quick&dirty way of backing up a pool that is a mirror of two devices is to
zpool attach a third one, wait for the resilvering to finish, then zpool detach
it again.
The third device then can be used as a poor man''s simple backup.
Has anybody tried it yet with a striped mirror? What if the pool is
composed out of two mirrors? Can I attach devices to both mirrors, let them

pool died during scrub
I have a bunch of sol10U8 boxes with ZFS pools, most all raidz2 8-disk
stripe. They''re all supermicro-based with retail LSI cards.
I''ve noticed a tendency for things to go a little bonkers during the
weekly scrub (they all scrub over the weekend), and that''s when I''ll
lose a disk here and there. OK, fine, that''s sort of the point, and
