[ceph-users] Massive Mon DB Size with noout on 14.2.11

Hello, we observed massive and sudden growth of the mon db size on disk, from 50MB to 20GB+ (GB!) and thus reaching 100% disk usage on the mountpoint. As far as we can see, it happens if we set "noout" for a node reboot: After the node and the OSDs come back it looks like the mon db size increased drastically. We have 14.2.11, 10 OSD @ 2TB and cephfs in use. Is this a known issue? Should we avoid noout?
