I had recently started setting up a homegrown OpenSolaris NAS with a large
RAIDZ2 pool, and had found its RAIDZ2 performance severely lacking - more like
downright atrocious. As originally set up:
* Asus M4A785-M motherboard
* Phenom II X2 550 Black CPU
* JMB363-based PCIe X1 SATA card (2 ports)

I'm currently on b134 (but I had the performance issues with 2009.06, b130,
b131, b132, and b133 as well).
I may end up swapping the Phenom II X2 550 with an Athlon II X4 630 that I've
put into another M4A785-M system. I noticed that the

It wasn't possible to do so, and that also made me think that a real HBA would
work better. First off, with the AMD SB700/SB800 on-board ports, if I set the

I have two 500 GB drives on my system that are attached to built-in SATA ports
on my Asus M4A785-M motherboard, running in AHCI mode. If I shut down the
system, remove either drive, and then try to boot the system, it will fail to
boot. If I disable the splash screen, I find that it will display

I waited about three minutes. This is a b134 installation.

OK, I just did some checking, and my rpool was already set up with
autoreplace=off. It's necessary to use the -r bo
I'm not having any luck hotswapping a drive attached to my Intel SASUC8I
(LSI-based) controller. The commands which work for the AMD AHCI ports don't
work for the LSI. Here's what "cfgadm -a" reports with all drives installed and
operational:

Good advice - ZFS can use quite a lot of CPU cycles. A low-end AMD q

I kicked off a scrub just to see, and we're scrubbing at 200MB/s (2

zpool-tank is using 3.2% CPU as shown by 'ps aux | grep tank'
