The fs.sh script checks if the file system is mounted (in the right
place), and occasionally does a simple write test (if the fs wasn't
mounted ro as per the resource options).  The write test is expected to
fail if the file system was remounted read only by the kernel.

The fs.sh script is a bit ugly, but it works.  Could be useful to start
from there.
