It says:
Searching for installed OS instances...
No installed OS instance found.
And then I'm at the single user prompt.

The result is the same as without a '-f'. With both -f and -F it says
"cannot open 'rpool': I/O error" and the pool disappears completely.
It no longer shows up when doing "zpool import". I have to reboot off
the DVD again to get it back.
I'm using an ASUS P5K-E motherboard and the on board SATA ports.
Could it be a motherboard problem? I've tried moving the SATA cables
to different ports but no change. I have a second pool on this
machine (called z2) on a separate disk (single disk - no redundancy).
Running "zpool import -f z2" on that pool succeeds but then it fails
with the following error: cannot mount '/z2': failed to create
mountpoint.
