RAID-Z1 pool became faulted when a disk was removed.
...nutes to give me console login. Commands took at
least 5s between being typed and appearing in console - it was obvious
something insane was going on. Load average was 6.33, and fmd was taking
most of the CPU. zpool status took about 10 minutes to tell me that it
thought c2t2d0 was missing and that c2t4d0 was corrupt, thereby screwing me.
Wait, what. I didn''t touch that disk, what''s going on here.
I try to convince ZFS that the disk is there and usable via zpool online

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

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

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? Or

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:

Lots of overhead with ZFS - what am I doing wrong?
I was trying to simply test bandwidth that Solaris/ZFS (Nevada b63) can deliver from a drive, and doing this:
dd if=(raw disk) of=/dev/null gives me around 80MB/s, while dd if=(file on ZFS) of=/dev/null gives me only 35MB/s!?. I am getting basically the same result whether it is single zfs drive, mirror or a stripe (I am testing with two Seagate 7200.10 320G drives hanging off the same interface

Can this be done?
I currently have a 7x1.5tb raidz1.
I want to add "phase 2" which is another 7x1.5tb raidz1
Can I add the second phase to the first phase and basically have two
raid5''s striped (in raid terms?)
Yes, I probably should upgrade the zpool format too. Currently running
snv_104. Also should upgrade to 110.
If that is possible, would anyone happen to have the simple command
lines to
