+* CephFS: Modifying the FS setting variable "max_mds" when a cluster is
+ unhealthy now requires users to pass the confirmation flag
+ (--yes-i-really-mean-it). This has been added as a precaution to tell the
+ users that modifying "max_mds" may not help with troubleshooting or recovery
+ effort. Instead, it might further destabilize the cluster.
