Fixed In Version: ceph-16.2.8-2.el8cp
Doc Type: Bug Fix
Doc Text:
.The `ceph orch redeploy mgr` command redeploys the active Manager daemon last Previously, the `ceph orch redeploy mgr` command would cause the Ceph Manager daemons to continually redeploy themselves without clearing the scheduled redeploy action which would result in the Ceph Manager daemons endlessly flapping. With this release, the ordering of the redeployment was adjusted so that the active manager daemon is always redeployed last and the command `ceph orch redeploy mgr` now only redeploys each Ceph Manager once.

This issue seems to be fixed in last releases. I tried to reproduce it both using 16.2.7 and master and couldn't observe this behavior in these branches. There's a PR (already merged) that seems to fix this issue. https://github.com/ceph/ceph/pull/41002.
