Hello! I have a cluster with Datacenter crushmap (A+B).(9+9 = 18 servers) The cluster started with v12.2.0 Luminous 4 years ago. All these years I upgraded the Cluster Luminous > Mimic > v14.2.16 Nautilus. Now I have a weird issue. When I add a mon or shutdown a while and start it up again, all the cluster suspends, ceph -s do not respond and other two monitors starting election while booting mon is syncing.

handle_auth_request failed to assign global_id The booting mon only gives this: mon.SRV-SB5@2(synchronizing) e9 handle_auth_request failed to assign global_id The booting mon prepares its *.stt tables and I watched the var/lib/ceph/mon/*/*/*.log file and I saw these logs: !osd_snapremoved_epoch_1_0013c460,�!osd_snapremoved_epoch_1_0013c462.� I guess after all these upgrades Ceph missed some variable or something else. The problem is huge because I can not bootstrap a mon without stopping entire cluster. It takes 30min to boot up... I tried to remove and add new mons but nothing changed. I've a backup service and it takes snapshots and backup to blockstorage and deletes the snapshot. It works for 3 years now and the snapremoved log in th mon log under "var/lib/ceph/mon/*/*/*.log" makes me wonder, what if all these snapshots makes huge bottleneck to the mon bootup? What should I do? _______________________________________________ ceph-users mailing list -- ceph-users@ceph.io To unsubscribe send an email to ceph-users-leave@ceph.io
