To summarise, putting 28 disks in a single vdev is nothing you would do if you
want performance. You'll end up with as many IOPS a single drive can do.
Split it up into smaller (10 disk) vdevs and try again. If you need high
performance, put them in a striped mirror (aka RAID1+0)

Victor,
The zpool import succeeded on the next attempt following the crash
that I reported to you by private e-mail!
For completeness, this is the final status of the pool:
pool: tank
state: ONLINE
scan: resilvered 1.50K in 165h28m with 0 errors on Sat
Compared to b134? Yes! We have fixed many bugs that still exist in 134.

Ok... so we've rebuilt the pool as 14 pairs of mirrors, each pair having one
disk in each of the two JBODs. Now we're getting about 500-1000 IOPS
(according to zpool iostat) and 20-30MB/sec in random read on a big database.
Does that sounds right?Seems right, as Erik said. Btw, do you use

What I don't understand is why, when I run a single query I get 100 IOPS
and 3MB/sec. The setup can obviously do better, so where is the
bottleneck? I don't see any CPU core on any side being maxed out so it
can't be it...
In what way is CPU contention being monitored? prstat without
options is nearly useless for a multithreaded app on a multi-CPU (or
multi-core/multi-thread) system. mpstat is only useful if threads
never migrate between CPU's. prstat -mL gives a nice picture of how
busy each LWP (thread)

Is that 38% of one CPU or 38% of all CPU's? How many CPU's does the
Linux box have? I don't mean the number of sockets, I mean number of
sockets * number of cores * number of threads per core. My
The server has two Intel X5570s, they are quad core and have hyperthreading.

Where can I find a list of these?
This leads to the more generic question of: where are *any* release notes?
I saw on Genunix that Community Edition 3.0.3 was replaced by 3.0.3-1. What
changed? I went to nexenta.org and looked around. But it wasn't immediately
obvious where to find release
