CephFS does not have a concept of "free inodes", inodes get allocated on-demand in the filesystem. This confuses alerting managers that expect a (high) number of free inodes, and warnings get produced if the number of free inodes is not high enough. This causes alerts to always get reported for CephFS. To prevent the false-positive alerts from happening, the NodeGetVolumeStats procedure for CephFS (and CephNFS) will not contain inodes in the reply anymore.
