Forced shutdown is used when an I/O error is reported by the
underlying layers. If everything else is working correctly it
usually means there is a hardware problem.
Once this has happened you can no longer access the filesystem, which
is why it looked empty, the only recourse is the one you took, unmount
and run repair.
The reasoning behind it is that if hardware is failing the best thing
to do is to stop writing to it and ask for administrative action to
clean it up.
On Linux there is a chance you have been bitten by a compiler whih
does not like the xfs code. I suppose with Raid 1 you may have
stumbled across a case where the raid reconstruction and xfs got in each
other's way. Is there any way you can tell if reconstruction was in
progress?
