Woud I then use zfs set quota=xxxG to handle disk usage?

Thanks Richard and Jim,
Your answers helped me to show to the customer that there was no issue
with ZFS and the HDS.

Richard,
I compared the libzfs_jni source code and they're pretty different
from what we're doing. libzfs_jni is essentially a jni wrapper to
(yet?) another set of zfs-related programs written in C. zfs for Java,
on the other hand, is a Java wrapper to the functionality of (and only
of) libzfs. I

I ended up having to put the flag into /etc/system. When I disabled the ZIL and

Dustin,
You didn't describe the process that you used to replace the disk so its
difficult to commment on what happened.
In general, you physically replace the disk and then let ZFS know that
the disk is replaced, like this:
# zpool replace pool-name device-name
This process is described here:
Tim: I couldn't do a zpool scrub, since the pool was marked as UNAVAIL.
Believe me, I tried :)
Bob: Ya, I realized that after I clicked send. My brain was a little frazzled,
so I completely overlooked it.

I replaced a bad disk in a RAID-Z2 pool, and now the pool won't come online.
Status shows nothing helpful at all. I don't understand why this is, which I
should be able to lose 2 drives, and I only replaced one!

I wonder if a taskq pool does not suffer from a similar

Hmmm...this is nothing in terms of load.

periodically, and you noticed the xcall storm when that
happens, correct?

of the sluggish cycles?
