I have a machine running 8.0-STABLE amd64 since last week, it was upgraded from 7.2.
Today I had a problem with the system hard drive and had to unplug all the drives to
get to it. When I plugged them back in they didn't go in the right order
and now both of my pools are broken.
I rearranged the cables in what I think is the right order but still no go.
One pool says all drives are online but the pool is broken.
The other lists ad13 twice in the list and ignores ad12, running in degraded mode.
What should I do?

still be used, but some features are unavailable.

pool will no longer be accessible on older software versions.
