write to a subdirectory on the RBD. so
if it is not mounted, the directory will be missing, and you get a
no such file error.

writable when the RBD is not mounted. It would write a file to
the system drive and you would see it as successful.
If you are
monitoring to ensure that it is mounted and active, a simple
check_disk on the mountpoint should work. If the mount is not
present, or the filesystem is non-responsive then this should
pick it up. A second check to perhaps test you can actually
write files to the file system would not go astray either.
Other than that I don't think there is much point checking
anything else like rbd mapped output.
