OK, I have finally settled on hardware;
2x LSI SAS3081E-R controllers
2x Seagate Momentus 5400.6 rpool disks
15x Hitachi 5K3000 'data' disks
I am still undecided as to how to group the disks. I have read elsewhere that
raid-z1 is best suited with either 3 or 5 disks and raid-z2 is better suited
The LSI2008 chipset is supported and works very well.
I would actually use 2 vdevs; 8 disks in each. And I would configure each vdev
as raidz2. Maybe use one hot spare.
And I also have personal, subjective reasons: I like to use the number of 8 in
computers. 7 is an ugly number. Everything is
Thanks.
I ruled out the SAS2008 controller as my motherboard is only PCIe 1.0 so would
not have been able to make the most of the difference in increased bandwidth.
I can't see myself upgrading every few months (my current WHZ build has lasted
over 4 years without a single change) so by the
Hey guys,
I had a zfs system in raidz1 that was working until there was a power outage
and now I'm getting this:
pool: tank
state: DEGRADED
status: One or more devices are faulted in response to IO failures.
action: Make sure the affected devices are connected, then run 'zpool clear'.
Ok so now I have no idea what to do. The scrub is not working either. The pool
is only 3x 1.5TB drives so it should not take so long. Does anyone know what I
should do next?

Here is my problem:
I have an 1.5TB disk with OpenSolaris (b134, b151a) using non AHCI.
I then changed to AHCI in BIOS, which results in severe problems: I can

Only PCIe 1.0? What chipset is that based on?
Hello,
Are you certain that after the outage your disks are indeed accessible?
* What does BIOS say?
* Are there any errors reported in dmesg output or the
/var/adm/messages file?
* Does the format command return in a timely manner?
** Can you access and print the disk labels in format command?
Ok, so I switch back and then I have my data back?
But, it does not work. Because, meanwhile I switched, I tried to zpool import
which messed up the drive. Then I switched back, but my data is still not
accessible.
Earlier, when I switched, I did not do a zpool import and when I switched

(But, importing the zpool with the name rpool and exporting the rpool again,
was successful. I can now use the disk as usual. But this did not work on the
