Hello,
I'm running FreeBSD 9.0/amd64, pure ZFS setup, one Seagate disk
ST2000NM0011 SN02 on LSI Logic (mpt) controller.
Yes, I know that running one disk on RAID controller is a bit weird, I
have to find yet if it is possible to connect disk to internal SATA
controller.
About two days ago, system became SLOW. Disk usage is constantly 100%,
and sometimes I'm getting swap_pager: indefinite wait buffer error. I
had to reset computer twice in two days.
mptutil does not show any errors, and smartctl shows

I have removed most of snapshots, it does not help.
I have stopped all active processes, disk load did not decrease, same 100%.
What can I check and/or replace to get the problem fixed? Any ideas?
Alex
