please help me.problem with my ceph

["=?gb18030?b?8KnUwg==?=" <suzhenhust@xxxxxx>]

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

;

; Sample ceph ceph.conf file.

;

; This file defines cluster membership, the various locations

; that Ceph stores data, and any other runtime options.

; If a 'host' is defined for a daemon, the init.d start/stop script will

; verify that it matches the hostname (or else ignore it).  If it is

; not defined, it is assumed that the daemon is intended to start on

; the current host (e.g., in a setup with a startup.conf on each

; node).

; The variables $type, $id and $name are available to use in paths

; $type = The type of daemon, possible values: mon, mds and osd

; $id = The ID of the daemon, for mon.alpha, $id will be alpha

; $name = $type.$id

; For example:

; osd.0

;  $type = osd

;  $id = 0

;  $name = osd.0

; mon.beta

;  $type = mon

;  $id = beta

;  $name = mon.beta
