Hello I'm trying to add MONs in advance of a planned downtime. This has actually ended up removing an existing MON, which isn't helpful. The error I'm seeing is: Invalid argument: /var/lib/ceph/mon/ceph-<hostname>/store.db: does not exist (create_if_missing is false) error opening mon data directory at '/var/lib/ceph/mon/ceph-<hostname>': (22) Invalid argument It appears that the fsid is being stripped, because the directory was there. It's now in /var/lib/ceph/<fsid>/removed This appears to be similar to: https://tracker.ceph.com/issues/45167 which was closed for lack of a reproducer. The command I ran was: sudo ceph orch apply mon --placement="comma-separated hostname list" after running that with "--dry-run". Would be grateful for some advice here - I wasn't expecting to reduce the MON count.
