Should not be a problem. I have 3 drives hooked up via eSATA myself and it
works great. I am not sure if you will have to power down and up to connect and
disconnect the drives though when you power the drives up and down.

Greetings learned ZFS geeks & guru’s,
Yet another question comes from my continued ZFS performance testing. This has
to do with zpool iostat, and the strangeness that I do see.
I’ve created an eight (8) disk raidz pool from a Sun 3510 fibre array giving me
a 465G volume.
# zpool create tp raidz
Something I was wondering about myself. What does the raidz toplevel (pseudo?)
device do? Does it just indicate to the SPA, or whatever module is responsible,
to additionally generate parity? The thing I'd like to know is if variable
block sizes, dynamic striping et al still applies to a single
Hi Lee,
You can decide whether you want to use ZFS for a root file system now.
You can find this info here:

Consider this setup for your other disks, which are:
250, 200 and 160 GB drives, and an external USB 2.0 600 GB drive
250GB = disk1

I think for the SoHo and home user scenarios, I think it might be of advantage
if the disk drivers offer unified APIs to read out and interpret disk drive
diagnostics, like SMART on AT
What are these alignment requirements?
I would have thought that at the lowest level, parity stripes would have been
allocated traditionally, while treating the remaining usable space like a JBOD
the level above, thus not subject to any restraints (apart when getting close
to the parity stripe
Cindy,
Thanks so much for the response -- this is the first one that I
consider an actual answer. :-)
I'm still unclear on exactly what I end up with. I apologize in
advance for my ignorance -- the ZFS admin guide assumes knowledge
that I don't yet have.
I assume that disk4 is a hot spa

Lee,
Yes, the hot spare (disk4) should kick if another disk in the pool fails
and yes, the data is moved to disk4.
You are correct:
160 GB (the smallest disk) * 3 + raidz parity info
Here's the size of raidz pool comprised of 3 136-GB disks:
# zpool list

I think it will be in the next.next (10.6) OSX, we just need to get apple to
stop playing with their silly cell phone (that I cant help but want, damn
them!).
I have similar situation at home, but what I do is use Solaris 10 on a
cheapish x86 box with 6 400gb IDE/SATA disks, I then make them into
I've been using long SATA cables routed out through the case to a home built
chassis with its own power supply for a year now. Not even eSATA. That part
works well.
Substitute this for USB/Firewire/SCSI/USB thumb drives. It's really the same
problem.
Ok, now you want to deal with a ZFS zpoo

How well does ZFS work on removable media? In a RAID configuration? Are there
issues with matching device names to disks?
I've had a zpool with 4-250Gb IDE drives in three places recently:
- in an external 4-bay Firewire case, attached to a Sparc box
- inside a dual-Opter
There's a video put out by some Sun people in Germany (IIRC) they
made several 4 RAIDZs on 3 USB hubs using a total of 12 USB
thumbdrives. At one point they pulled all the USB sticks, shuffled
them and then re-imported the pool. Worked like butter.
