Hi Sam, The daemons restart (for *some* releases) because of this: https://tracker.ceph.com/issues/21672 In short, if the selinux module changes, and if you have selinux enabled, then midway through yum update, there will be a systemctl restart ceph.target issued. For the rest -- I think you should focus on getting the PGs all active+clean as soon as possible, because the degraded and remapped states are what leads to mon / osdmap growth. This kind of scenario is why we wrote this tool: https://github.com/cernceph/ceph-scripts/blob/master/tools/upmap/upmap-remapped.py It will use pg-upmap-items to force the PGs to the OSDs where they are currently residing. But there is some clarification needed before you go ahead with that. Could you share `ceph status`, `ceph health detail`?
