determining raidz pool configuration
Hi all,
Sorry for the newbie question, but I''ve looked at the docs and haven''t
been able to find an answer for this.
I''m working with a system where the pool has already been configured and
want to determine what the configuration is. I had thought that''d be
with zpool status -v <poolname>, but it doesn''t seem to agree with the

How to replace root drive if ZFS data is on it?
Hi, Experts:
A customer has X4500 and the boot drives mirrored (c5t0d0s0 and
c5t4d0s0) by SVM,
The ZFS uses the two other partitions on these two drives(c5t0d0s3 and
c5t4d0s3).
If we need to replace the disk drive c5t0d0, do we need to do anything
on the ZFS
(c5t0d0s3 and c5t4d0s3) first or just follow the regular boot drive
replacement procedure?
Below is the summary of their current ZFS

zpool degraded status after resilver completed
I am curious why zpool status reports a pool to be in the DEGRADED state
after a drive in a raidz2 vdev has been successfully replaced. In this
particular case drive c0t6d0 was failing so I ran,
zpool offline home/c0t6d0
zpool replace home c0t6d0 c8t1d0
and after the resilvering finished the pool reports a degraded state.
Hopefully this is incorrect. At this point is the vdev in question

Mixing RAIDZ and RAIDZ2 zvols in the same zpool
I have a customer who has implemented the following layout: As you can
see, he has mostly raidz zvols but has one raidz2 in the same zpool.
What are the implications here? Is this a bad thing to do? Please
elaborate.
Thanks,

x4500 resilvering spare taking forever?
I''ve got a Thumper running snv_57 and a large ZFS pool. I recently noticed a drive throwing some read errors, so I did the right thing and zfs replaced it with a spare.
Everything went well, but the resilvering process seems to be taking an eternity:

understanding zfs/thunoer "bottlenecks"?
Currently I''m trying to figure out the best zfs layout for a thumper wrt. to read AND write performance.
I did some simple mkfile 512G tests and found out, that per average ~ 500 MB/s seems to be the maximum on can reach (tried initial default setup, all 46 HDDs as R0, etc.).
According to http://www.amd.com/us-en/assets/content_type/DownloadableAssets/ArchitectureWP_062806.pdf I would

ZFS error handling - suggestion
Howdy,
I have at several times had issues with consumer grade PC hardware and ZFS not getting along. The problem is not the disks but the fact I dont have ECC and end to end checking on the datapath. What is happening is that random memory errors and bit flips are written out to disk and when read back again ZFS reports it as a checksum failure:

ZFS thinks my 7-disk pool has imaginary disks
Hi all,
I recently created a RAID-Z1 pool out of a set of 7 SCSI disks, using the
following command:
# zpool create magicant raidz c5t0d0 c5t1d0 c5t2d0 c5t3d0 c5t4d0 c5t5d0
c5t6d0
It worked fine, but I was slightly confused by the size yield (99 GB vs the
116 GB I had on my other RAID-Z1 pool of same-sized disks).
I thought one of the disks might have been to blame, so I tried swapping it

How to properly read "zpool iostat -v" ? ;)
Hello experts,
I''ve had a lingering question for some time: when I
use "zpool iostat -v" the values do not quite sum up.
In the example below with a raidz2 array made of 6
drives:
* the reported 33K of writes are less than two disks''
workload at this time (at 17.9K each), overall
disks writes are 107.4K = 325% of 33K.
* write ops sum up to 18 = 225% of 8 ops to

USB sticks show on one set of devices in zpool, different devices in format
Hello,
I had snv_111b running for a while on a HP DL160G5. With two 16GB USB sticks comprising the mirrored rpool for boot. And four 1TB drives comprising another pool, pool1, for data.
So that''s been working just fine for a few months. Yesterday I get it into my mind to upgrade the OS to latest, then was snv_127. That worked, and all was well. Also did an upgrade to the

ZFS locking up! Bug in ZFS, device drivers or time for mobo RMA?
Greetings all.
I am facing serious problems running ZFS on a storage server assembled out of commodity hardware that is supposed to be Solaris compatible.
Although I am quite familiar with Linux distros and other unices, I am new to Solaris so any suggestions are highly appreciated.

file access algorithm within pools
Hello,
What is the access algorithm used within multi-component pools for a
given pool, and does it change when one or more members of the pool
become degraded ?
examples:

c5t0d0 c6t0d0
or;
zpool create ztank raidz c1t0d0 c2t0d0 c3t0d0 raidz c4t0d0 c5t0d0 c6t0d0
As files are created on the filesystem within these pools,

Help! ZFS pool is UNAVAILABLE
Hi All,
I posted this in a different threat, but it was recommended that I post in this one.
Basically, I have a 3 drive raidz array on internal Seagate drives. running build 64nv. I purchased 3 add''l USB drives with the intention of mirroring and then migrating the data to the new USB drives.
I accidentally added the 3 USB drives in a raidz to my original storage pool, so now I have 2

questions about replacing a raidz2 vdev disk with a larger one
I''d like to replace/upgrade two 500GB disks in RaidZ2 vdev with 1TB disks, but I have some preliminary questions/concerns before trying ''zfs replace dpool ?''
Will ZFS permit this replacement?
Will ZFS use the extra space in a heterogeneous RaidZ2 vdev, or is the size limited by the smallest disk in the vdev?
Thanks in advance,
