Running ceph version 0.67.5. I've an OSD server with 3 OSDs; sdb sdc and sdd. sdb and sdc have fallen out, so I've removed and readded them. But both OSDs I'm attempting to add refuse to start:- root@ceph-3:~# /etc/init.d/ceph start osd.6 /etc/init.d/ceph: osd.6 not found (/etc/ceph/ceph.conf defines mon.ceph-3 osd.8 , /var/lib/ceph defines mon.ceph-3 osd.8) It's true, they're not defined, but neither are the other 6 OSDs. Here is ceph.conf:- [global] fsid = 6c0cbf2a-8b30-4b03-b4f5-6d56386b1c14 mon_initial_members = ceph-1,ceph-3 mon_host = 10.11.4.52 auth_supported = cephx osd_journal_size = 1024 filestore_xattr_use_omap = true _______________________________________________ ceph-users mailing list ceph-users@xxxxxxxxxxxxxx http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com
