checking '$server:$subdir' is too strict to work in all cirumcstances,
e.g. adding/removing a monitor would mean that it is not the same
anymore, same if one is adding/removing the ports from the config
check only if the subdir is the same and if it is a cephfs
this way, it still returns true if someone changes the config
