We execute mmbackup via a regular TSM client schedule with an incremental
action, with a virtualmountpoint set to an empty, local "canary" directory.
mmbackup runs as a preschedule command, and the client -domain parameter is
set only to backup the canary directory. dsmc will backup the canary
directory as a filespace only if mmbackup succeeds (exits with 0). We can
then monitor the canary and infer the status of the associated GPFS
filespace or fileset.
