Hi 皓月,

You can try "ls -al /mnt/ceph ", check if the current user have W/R access to the directory. Maybe you need to use "chown" to change the directory owner.

Kai

 1.  I have installed ceph with one mon/mds and one osd.When i use 'ceph -s',there si a warning:health HEALTH_WARN 384 pgs degraded; 384 pgs stuck unclean; recovery 21/42 degraded (50.000%)
2. i mount a client.'192.168.3.189:/       100G 1009M   97G   2% /mnt/ceph' 
 but i can't creat a file or a directory because of no permission.
my conf is listed bellow.please tell my how to fix these problems,thanks
