Thanks a lot for the great ceph.conf pointer, Mykola! I found something interesting: 2017-09-11 22:26:23.418796 7efd7d479700 10 client.1039597.objecter ms_dispatch 0x55b55ab8f950 osd_op_reply(4 rbd_header.df7343d1b58ba [call] v0'0 uv0 ondisk = -8 ((8) Exec format error)) v8 2017-09-11 22:26:23.439501 7efd7dc7a700 10 client.1039597.objecter ms_dispatch 0x55b55ab8f950 osd_op_reply(14 rbd_header.2b0c02ae8944a [call] v0'0 uv0 ondisk = -8 ((8) Exec format error)) v8 Not sure if those are the ones causing the problem, but at least some error. I have uploaded the log at http://www.nico.schottelius.org/ceph.client.libvirt.41670.log.bz2 I wonder if anyone sees the real reason for the I/O errors in the log?
