RAID-Z1 pool became faulted when a disk was removed.
So I have attached to my system two 7-disk SCSI arrays, each of 18.2 GB
disks.
Each of them is a RAID-Z1 zpool.
I had a disk I thought was a dud, so I pulled the fifth disk in my array and
put the dud in. Sure enough, Solaris started spitting errors like there was
no tomorrow in dmesg, and wouldn''t use the disk. Ah well. Remove it, put the
original back in - hey, Solaris still thinks

ZFS panic while mounting lofi device?
I believe ZFS is causing a panic whenever I attempt to mount an iso image (SXCR build 39) that happens to reside on a ZFS file system. The problem is 100% reproducible. I''m quite new to OpenSolaris, so I may be incorrect in saying it''s ZFS'' fault. Also, let me know if you need any additional information or debug output to help diagnose things.

Sol 10 x86_64 intermittent SATA device locks up server
Hello All,
I have an issue where I have two SATA cards with 5 drives each in one
zfs pool. The issue is one of the devices has been intermittently
failing. The problem is that the entire box seems to lock up on
occasion when this happens. I currently have the SATA cable to that
device disconnected in the hopes that the box will at least stay up for
now. This is a new build that I am

A few Newbie questions about RAIDZ
1. I have a 4x18GB drive setup as RAIDZ. Now when thinking about it
in terms of RAID5 I would expect to get (4-1)x18 worth of drive
space, but DF -h shows 4x18. Is this a bug or do I not understand?
2. Once again thinking in RAID5 terms if I have 4X18GB and 12X9GB
drives and I want to make a RAIDZ of all of them I would expect the
18GB to be treated at 9GB so the RAIDZ would be 16X9GB. Is

Hardware RAID vs. ZFS RAID
Hello,
I have a Dell 2950 with a Perc 5/i, two 300GB 15K SAS drives in a RAID0 array. I am considering going to ZFS and I would like to get some feedback about which situation would yield the highest performance: using the Perc 5/i to provide a hardware RAID0 that is presented as a single volume to OpenSolaris, or using the drives separately and creating the RAID0 with OpenSolaris and ZFS?

cannot replace c10t0d0 with c10t0d0: device is too small
In 2007 I bought 6 WD1600JS 160GB sata disks and used 4 to create a raidz storage pool and then shelved the other two for spares. One of the disks failed last night so I shut down the server and replaced it with a spare. When I tried to zpool replace the disk I get:

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

drive displayed multiple times
So I just imported an old zpool onto this new system. The problem would be one drive (c4d0) is showing up twice. First it''s displayed as ONLINE, then it''s displayed as "UNAVAIL". This is obviously causing a problem as the zpool now thinks it''s in a degraded state, even though all drives are there, and all are online.
This pool should have 7 drives total,

Expanding a ZFS pool disk in Solaris 10 on VMWare (or other expandable storage technology)
Hello all,
This is not so much a question but rather a "how-to" for posterity.
Comments and possible fixes are welcome, though.
I''m toying (for work) with a Solaris 10 VM, and it has a dedicated
virtual HDD for data and zones. The template VM had a 20Gb disk,
but a particular application needs more. I hoped ZFS autoexpand
would do the trick transparently, but it turned out

OpenSolaris ZFS NAS Setup
If it''s of interest, I''ve written up some articles on my experiences of building a ZFS NAS box which you can read here:
http://breden.org.uk/2008/03/02/a-home-fileserver-using-zfs/
I used CIFS to share the filesystems, but it will be a simple matter to use NFS instead: issue the command ''zfs set sharenfs=on pool/filesystem'' instead of ''zfs set

7-disk raidz achieves 430 MB/s reads and 220 MB/s writes on a $1320 box
I figured the following ZFS ''success story'' may interest some readers here.
I was interested to see how much sequential read/write performance it would be
possible to obtain from ZFS running on commodity hardware with modern features
such as PCI-E busses, SATA disks, well-designed SATA controllers (AHCI,
SiI3132/SiI3124). So I made this experiment of building a fileserver by

ZFS, XFS, and EXT4 compared
I have a lot of people whispering "zfs" in my virtual ear these days,
and at the same time I have an irrational attachment to xfs based
entirely on its lack of the 32000 subdirectory limit. I''m not afraid of
ext4''s newness, since really a lot of that stuff has been in Lustre for
years. So a-benchmarking I went. Results at the bottom:
