  To avoid known issue with kernel FS client it is recommended to use
  'readdir_max_entries' mount option, for example:
 
     mount -t ceph 1.2.3.4:/ /mnt/ceph -o readdir_max_entries=64

+ Beware of "mlocate" scanning of OSD file systems. To avoid problems add
+ "/var/lib/ceph" to PRUNEPATHS in the "/etc/updatedb.conf" like in the
+ following example:
+
+    PRUNEPATHS="/tmp /var/spool /media /mnt /var/lib/ceph"
