I might have a reproducer, the second rebuilt mon is not joining the cluster as well, I'll look into it and let you know if I find anything. Zitat von Eugen Block <eblock@xxxxxx>:Hi,Can anyone confirm that ancient (2017) leveldb database mons should just accept ‘mon.$hostname’ names for mons, a well as ‘mon.$id’ ?at some point you had or have to remove one of the mons to recreate it with a rocksdb backend, so the mismatch should not be an issue here. I can confirm that when I tried to reproduce it in a small test cluster with leveldb. So now I have two leveldb MONs and one rocksdb MON: jewel:~ # cat /var/lib/ceph/b08424fa-8530-4080-876d-2821c916d26c/mon.jewel/kv_backend rocksdb jewel2:~ # cat /var/lib/ceph/b08424fa-8530-4080-876d-2821c916d26c/mon.jewel2/kv_backend leveldb jewel3:~ # cat /var/lib/ceph/b08424fa-8530-4080-876d-2821c916d26c/mon.jewel3/kv_backend leveldb And the cluster is healthy, although it took a minute or two for the rebuilt MON to sync (in a real cluster with some load etc. it might take longer): jewel:~ # ceph -s cluster: id: b08424fa-8530-4080-876d-2821c916d26c health: HEALTH_OK services: mon: 3 daemons, quorum jewel2,jewel3,jewel (age 3m) I'm wondering if this could have to do with the insecure_global_id things. Can you send the output of: ceph config get mon auth_allow_insecure_global_id_reclaim ceph config get mon auth_expose_insecure_global_id_reclaim ceph config get mon mon_warn_on_insecure_global_id_reclaim ceph config get mon mon_warn_on_insecure_global_id_reclaim_allowed Zitat von Mark Schouten <mark@xxxxxxxx>:Hi, I don’t have a fourth machine available, so that’s not an option unfortunatly. I did enable a lot of debugging earlier, but that shows no information as to why stuff is not working as to be expected. Proxmox just deploys the mons, nothing fancy there, no special cases.

There are a couple of things I would try, not necessarily in this order: - Check the troubleshooting guide [1], for example a clock skew could be one reason, have you verified ntp/chronyd functionality? - Inspect debug log output, maybe first on the probing mon and if those don't reveal the reason, enable debug logs for the other MONs as well: ceph config set mon.proxmox03 debug_mon 20 ceph config set mon.proxmox03 debug_paxos 20 or for all MONs: ceph config set mon debug_mon 20 ceph config set mon debug_paxos 20 - Try to deploy an additional MON on a different server (if you have more available) and see if that works. - Does proxmox log anything? - Maybe last resort, try to start a MON manually after adding it to the monmap with the monmaptool, but only if you know what you're doing. I wonder if the monmap doesn't get updated... Regards, Eugen [1] https://docs.ceph.com/en/latest/rados/troubleshooting/troubleshooting-mon/ Zitat von Mark Schouten <mark@xxxxxxxx>:Hi, During an upgrade from pacific to quincy, we needed to recreate the mons because the mons were pretty old and still using leveldb. So step one was to destroy one of the mons. After that we recreated the monitor, and although it starts, it remains in state ‘probing’, as you can see below. No matter what I tried, it won’t come up. I’ve seen quite some messages that the MTU might be an issue, but that seems to be ok: root@proxmox03:/var/log/ceph# fping -b 1472 10.10.10.{1..3} -M 10.10.10.1 is alive 10.10.10.2 is alive 10.10.10.3 is alive Does anyone have an idea how to fix this? I’ve tried destroying and recreating the mon a few times now. Could it be that the leveldb mons only support mon.$id notation for the monitors? root@proxmox03:/var/log/ceph# ceph daemon mon.proxmox03 mon_status { "name": “proxmox03”, "rank": 2, "state": “probing”, "election_epoch": 0, "quorum": [], "features": { "required_con": “2449958197560098820”, "required_mon": [ “kraken”, “luminous”, “mimic”, "osdmap-prune”, “nautilus”, “octopus”, “pacific”, "elector-pinging” ], "quorum_con": “0”, "quorum_mon": [] }, "outside_quorum": [ “proxmox03” ], "extra_probe_peers": [], "sync_provider": [], "monmap": { "epoch": 0, "fsid": "39b1e85c-7b47-4262-9f0a-47ae91042bac”, "modified": "2024-01-23T21:02:12.631320Z”, "created": "2017-03-15T14:54:55.743017Z”, "min_mon_release": 16, "min_mon_release_name": “pacific”, "election_strategy": 1, "disallowed_leaders: ": “”, "stretch_mode": false, "tiebreaker_mon": “”, "removed_ranks: ": “2”, "features": { "persistent": [ “kraken”, “luminous”, “mimic”, "osdmap-prune”, “nautilus”, “octopus”, “pacific”, "elector-pinging” ], "optional": [] }, "mons": [ { "rank": 0, "name": “0”, "public_addrs": { "addrvec": [ { "type": “v2”, "addr": "10.10.10.1:3300”, "nonce": 0 }, { "type": “v1”, "addr": "10.10.10.1:6789”, "nonce": 0 } ] }, "addr": "10.10.10.1:6789/0”, "public_addr": "10.10.10.1:6789/0”, "priority": 0, "weight": 0, "crush_location": “{}” }, { "rank": 1, "name": “1”, "public_addrs": { "addrvec": [ { "type": “v2”, "addr": "10.10.10.2:3300”, "nonce": 0 }, { "type": “v1”, "addr": "10.10.10.2:6789”, "nonce": 0 } ] }, "addr": "10.10.10.2:6789/0”, "public_addr": "10.10.10.2:6789/0”, "priority": 0, "weight": 0, "crush_location": “{}” }, { "rank": 2, "name": “proxmox03”, "public_addrs": { "addrvec": [ { "type": “v2”, "addr": "10.10.10.3:3300”, "nonce": 0 }, { "type": “v1”, "addr": "10.10.10.3:6789”, "nonce": 0 } ] }, "addr": "10.10.10.3:6789/0”, "public_addr": "10.10.10.3:6789/0”, "priority": 0, "weight": 0, "crush_location": “{}” } ] }, "feature_map": { "mon": [ { "features": “0x3f01cfbdfffdffff”, "release": “luminous”, "num": 1 } ] }, "stretch_mode": false } — Mark Schouten CTO, Tuxis B.V. +31 318 200208 / mark@xxxxxxxx _______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx_______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx_______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx_______________________________________________ ceph-users mailing list -- ceph-users@xxxxxxx To unsubscribe send an email to ceph-users-leave@xxxxxxx
