Heya, ever since we had that one osd causing the entire cluster to hang (it's been removed since), we keep having hard to debug issues. for example sometimes on start, qemu just hangs forever. when i kill it manually, the next start works fine. when i map the same volume using krbd on another host, it also appears fine. How would you debug an issue like this? Since it happens before the vm even starts, i'm assuming it must be the mon that hangs? 'rbd lock ls' is empty, thats not it. is this possibly caused by running inconsistent mon versions? How would i know? ceph tell mon.\* version mon.mon-yca4ceph: { "version": "16.2.11", "release": "pacific", "release_type": "stable" } mon.mon-yca5ceph: { "version": "16.2.6", "release": "pacific", "release_type": "stable" } mon.mon-yca6ceph: { "version": "16.2.11", "release": "pacific", "release_type": "stable" } -- +4916093821054
