Hi Cephers At the moment we are trying to recover our CEPH cluser (0.87) which is behaving very odd. What have been done : 1. OSD drive failure happened - CEPH put OSD down and out. 2. Physical HDD replaced and NOT added to CEPH - here we had strange kernel crash just after HDD connected to the controller. 3. Physical host rebooted. 4. CEPH started restoration and putting OSD's down one by one (actually I can see osd process crush in logs). ceph.conf is in attachment.
