ceph osd down et rgw Initialisation timeout, échec de l'initialisation après le redémarrage

Centos7.2, Ceph avec 3 OSD, 1 MON fonctionnant sur un même nœud. radosgw et tous les démons fonctionnent sur le même nœud, et tout fonctionnait bien. Après le redémarrage du serveur, tous les OSD n'ont pas pu communiquer (apparemment) et radosgw ne fonctionne pas correctement, son journal dit :

2016-03-09 17:03:30.916678 7fc71bbce880  0 ceph version 0.94.6 (e832001feaf8c176593e0325c8298e3f16dfb403), process radosgw, pid 24181
2016-03-09 17:08:30.919245 7fc712da8700 -1 Initialization timeout, failed to initialize

ceph health montre :

HEALTH_WARN 1760 pgs stale; 1760 pgs stuck stale; too many PGs per OSD (1760 > max 300); 2/2 in osds are down

y ceph osd tree donner :

y service ceph status les résultats :

et ceci est service radosgw status :

Voyant cela, j'ai essayé sudo /etc/init.d/ceph -a start osd.1 and stop for a couple of times, mais le résultat est le même que ci-dessus.

sudo /etc/init.d/ceph -a stop osd.1
=== osd.1 ===

sudo /etc/init.d/ceph -a start osd.1
=== osd.1 ===

Merci de m'aider.

EDIT : il semble que mon ne peut pas parler à osd. mais les deux démons fonctionnent correctement. le journal d'osd montre :
