RAIDZ v. RAIDZ1
So, I took four 1.5TB drives and made RAIDZ, RAIDZ1 and RAIDZ2 pools. The sizes for the pools were 5.3TB, 4.0TB, and 2.67TB respectively. The man page for RAIDZ states that "The raidz vdev type is an alias for raidz1." So why was there a difference between the sizes for RAIDZ and RAIDZ1? Shouldn''t the size be the same for "zpool create raidz ..." and "zpool

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,

offlining a slice in a raidz not allowed
I''ve a raidz1 made up of 2 partitions. One is on a disk which is failing and
i want to replace it... cfgadm does not allow me to unconfigure it since
''device busy'', so i am trying to offline the slice from the raidz1 vdev but
got this error:

Expanding a raidz vdev in zpool
Hello All,
I have a zpool that consists of 2 raidz vdevs (raidz1-0 and raidz1-1). The
first vdev is 4 1.5TB drives. The second was 4 500GB drives. I replaced the
4 500GB drives with 4 3TB drives.
I replaced one at time, and resilvered each. Now the process is complete, I
expected to have an extra 10TB (4*2.5TB) of raw space, but it''s still the
same amount of space.
I did an export and

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

Extremely slow raidz resilvering
Hello everyone,
As one of the steps of improving my ZFS home fileserver (snv_134) I wanted
to replace a 1TB disk with a newer one of the same vendor/model/size because
this new one has 64MB cache vs. 16MB in the previous one.
The removed disk will be use for backups, so I thought it''s better off to
have a 64MB cache disk in the on-line pool than in the backup set sitting

How do you "re-attach" a 3 disk RAIDZ array to a new OS installation?
Hi,
I''m completely new to Solaris, but have managed to bumble through installing it to a single disk, creating an additional 3 disk RAIDZ array and then copying over data from a separate NTFS formatted disk onto the array using NTFS-3G.
However, the single disk that was used for the OS installation has since died (it was very old) and I have had to reinstall 2008.11 from scratch onto a

Different Sized Disks Recommendation
Hi,
I was first attracted to ZFS (and therefore OpenSolaris) because I thought that ZFS allowed the used of different sized disks in raidz pools without wasted disk space. Further research has confirmed that this isn''t possible--by default.
I have seen a little bit of documentation around using ZFS with slices. I think this might be the answer, but I would like to be sure what the

zfs raidz questions
Hi there,
i''m building a small NAS with 5x1TB Disks. The disks contains at the moment some data, ntfs as the fs and aren''t a raid.
Now my im wondering if its possible to add the parity later. So that i add step by step one disk to the pool. And when i add the last disk, i enable the parity.
(i have only one another 1 tb disk to backup the files)
Thank you for you replies and

raidz pool metadata corrupted nexanta-core->freenas 0.7->nexanta-core
I made a bad judgment and now my raidz pool is corrupted. I have a
raidz pool running on Opensolaris b85. I wanted to try out freenas 0.7
and tried to add my pool to freenas.
After adding the zfs disk,
vdev and pool. I decided to back out and went back to opensolaris. Now
my raidz pool will not mount and got the following errors. Hope someone
expert can help me recover from this error.

ZFS RAID-Z2 degraded vs RAID-Z1
Had an idea, could someone please tell me why it''s wrong? (I feel like it has to be).
A RaidZ-2 pool with one missing disk offers the same failure resilience as a healthy RaidZ1 pool (no data loss when one disk fails). I had initially wanted to do single parity raidz pool (5disk), but after a recent scare decided raidz2 was the way to go. With the help of a sparse file

checksum errors increasing on "spare" vdev?
Hi,
One of my colleagues was confused by the output of ''zpool status'' on a pool
where a hot spare is being resilvered in after a drive failure:
$ zpool status data
pool: data
state: DEGRADED
status: One or more devices is currently being resilvered. The pool will
continue to function, possibly in a degraded state.
action: Wait for the resilver to complete.

Data distribution not even between vdevs
Hi list,
My zfs write performance is poor and need your help.
I create zpool with 2 raidz1. When the space is to be used up, I add 2
another raidz1 to extend the zpool.
After some days, the zpool is almost full, I remove some old data.
But now, as show below, the first 2 raidz1 vdev usage is about 78% and the
last 2 raidz1 vdev usage is about 93%.

Assistance needed expanding RAIDZ with larger drives
Hi all,
Please can you help with my ZFS troubles:
I currently have 3 x 400 GB Seagate NL35''s and a 500 GB Samsung Spinpoint in a RAIDZ array that I wish to expand by systematically replacing each drive with a 750 GB Western Digital Caviar.
After failing miserably, I''d like to start from scratch again if possible. When I last tried, the replace command hung for an age, network

raidz failure, trying to recover
Long story short, my cat jumped on my server at my house crashing two drives at the same time. It was a 7 drive raidz (next time ill do raidz2).
The server crashed complaining about a drive failure, so i rebooted into single user mode not realizing that two drives failed. I put in a new 500g replacement and had zfs start a replace operation which failed at about 2% because there was two broken

Mixing RAID levels in a pool
Hi,
I had a plan to set up a zfs pool with different raid levels but I ran
into an issue based on some testing I''ve done in a VM. I have 3x 750
GB hard drives and 2x 320 GB hard drives available, and I want to set
up a RAIDZ for the 750 GB and mirror for the 320 GB and add it all to
the same pool.
I tested detaching a drive and it seems to seriously mess up the
entire pool and I
