Last night I was trying to setup nfs to share a pool. It was working fine until
I started to have trouble writing. I did a zpool status to see if everything was
ok, and I got this.
pool: spool
state: UNAVAIL
status: One or more devices are faulted in response to IO failures.
action: Make sure the affected devices are connected, then run ''zpool
clear''.
see: http://www.sun.com/msg/ZFS-8000-HC
scrub: none requested
config:

After doing zpool clear it resilvered to the spares.
pool: spool
state: ONLINE

I then tried to figure out why it was using the spares when it says c8t516d0 and
c8t548d0 are online. So, I tried doing zpool detach spool c8t3d0. There was a
lot of hd activity for a short period, then nothing. But the zpool command never
exited. When I run zpool status or zpool list they just hang, even df hangs. I
can still access the pool though and all my files. My motherboard has an ich10
with 6 sata ports. 4 drives are connected to it internally, then i have an
external enclosure with a sil3726 port multiplier with 4 drives in it connected
to my motherboard''s sata port through a sata-esata pci bracket. I am
using snv_130.
