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.

Additionally, solely testing if you can write to the path could give a
false sense of security if the path is 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.
