I note that you didn't say which filesystem you are using or wether they are
mounted ro or rw.  For most filesystems, you can only multi-mount them if
all the mounts are read-only.  If you want to mount read-write, then the
partition can only be mounted once.  Some of the weird filesystem issues you
mentioned in your first email might be explained by multiple rw mounts.
Also, perhaps the rising load average is your filesystem driver trying to
deal with the corrupted partition.

If you're using read-only mounts, GFS, or OCFS2, then ignore this.
