And actually, if you must have a write link, you should only specify
M, not MR.  If some other user has a write link already, MR will give
you a read link, which won't let you do what you need to do and can
cause you other confusion when you get errors trying to write on the
disk.  So specify M, and if you can't get the disk linked R/W, then it
will fail, and you will see in the error message what other user has
the disk already linked R/W.

I frequently see VM directory entries for Linux machines with the link
modes of the disks specified as MR instead of M.  I'd rather have
Linux completely fail to start up if some other userid has one or more
of its disks linked R/W than to start up with a disk linked read only
and get a lot of errors, later failures, etc.
