Thanks for the continuing flow of information. I already have all of the
equipment. I'm actually upgrading my main computer to a new Core 2 Duo setup
which is why this hardware is going to the file server. I think I'm going to

Hi !
I was in the middle of very long and boring transatlantic flight and
played with zfs and gzip compression on my laptop. And I just
thought that it may be quite useful for your shell to be able to
autocomplete the arguments to the zfs/zpool command.
So I quickly hacked together a script which
I would personally avoid the P4 chip. They are power hogs and will cost you
more money in the long run than getting a low-end core 2 duo - which should be
faster and not much more money. Make sure you keep power consumption in mind
when you pick up a power supply and video card too. The always o
The ZFS boot disk support we need has to be SPARC-based and our standards would
require that the support be present in the commercial Solaris 10 code-base,
unfortunately.
Your comments and observations are welcome input. I thank you very much for
your time and effort in replying. :-)

Onboard RAID solutions actually do all their work on your CPU, so you won't be
using that for anything if you use ZFS. You just want them acting like regular
SATA controllers.
Just run the Solaris hardware compatibility thinger (google it), or compare
your hardware to the supported hardware
With b62, he can do ZFS mirror for root in addition to the raidz for the
data but it would still require a second root drive...

How do you configure ZFS RAID 1+0 ?
Will next lines do that right? :
[b]zpool create -f zfs_raid1 mirror c0t1d0 c1t1d0
zpool add zfs_raid1 mirror c2t1d0 c3t1d0
zpool add zfs_raid1 mirror c4t1d0 c5t1d0[/b]

While trying some things earlier in figuring out how zpool iostat is supposed
to be interpreted, I noticed that ZFS behaves kind of weird when writing data.
Not to say that it's bad, just interesting. I wrote 160MB of zeroed data with
dd. I had zpool iostat running with an one second interval.

Bryan,
Thanks for your suggestion. I am looking at this as more of a DR solution.
However, I might be able to use your method if my data can be a little old.

Yes. I am used to dealing with the array based software you mention in your

Hi!
I have installed svn_62 a few days ago and thought to give zfs boot a try. I
followed the manual instructions and was able to get everything up and running
with a zfs boot/root environment.
After some tweaking (adding 2. Disk to the rootpool, moving some files from
some old zfs fs to the
If you were really worried about it you could mount forcedirect IO or
something, however, if you read the post, I mentioned to do it as a spare. A
spare isn't active until there's a problem, so you'd only be running with the
filedevice temporarily in theory anyway.

I hope it will be released soon. I asked Jiri about it and didn't get a
negative reply so I am optimistic now.

Hi.
bash-3.00# uname -a
SunOS 5.10 Generic_125101-04 i86pc i386 i86pc
Server is x4100.
NFS server under Sun Cluster with ZFS.
I issued 'zpool import' to see other pool available to import on one node and
then I got very slow nfs access to that node, nfsd go upto ~3500 threads (from
~500)

I've used ZFS to back up my laptops to an external USB disk that formed one
half of the mirror for a long while.
See: http://blogs.sun.com/chrisg/entry/external_usb_disk_drive
I recently stopped doing that in favour of doing the same to iSCSI luns hosted
on ZFS ZVOLs on a server:

I'd recommend getting a second 80GB disk and mirroring your root as well.
UFS+SDS for root (don't forget a live upgrade slice) and ZFS for the other
disks.
Probably RAID-Z as you don't have enough disks to be interesting for doing 1+0.

Sorry about that, the specific processor in question is the Pentium D 930 which
supports 64 bit computing through the Extended Memory 64 Technology. It was my
initial reaction to say I'd go with 32 bit computing because my general
experience with 64-bit is Windows, Linux, and some FreeBSD. Gen
Same here, needed ASAP. It's a shame Jiri can't release his work-in-progress
code, I've asked for a prerelease (even untested) version several times.

The original thought was 3 of the drives as storage, and one of the drives as
parity. So that would yield around 1.4TB of useable storage. I hadn't given
any thought to running 64 bit. This system is being built from the ground up.
