Help! zpool corrupted!

Can you run "iostat -x 1" while while youre zfs mount -a hangs? It
will probably indicate that there is 100% disk utilization on the disk
in question, indicating there is one or more I/O request(s)
outstanding to the device, indicating a
driver/controller/cabling/drive problem.

If on the other hand 'zfs mount -a' hangs but there is no ongoing
attempts at disk I/O according to iostat, there may be a software
problem with zfs or something else, although since you have confirmed
disk-related issues it might have been triggered by actual on-disk
corruption.
