Good morning, this week I observed something new, I think. At least I can't recall having seen that yet. Last week I upgraded a customer cluster to 18.2.4 (everything worked fine except RGWs keep crashing [0]), this week I reinstalled the OS on one of the hosts. And after a successful registry login, the OSDs were automatically activated without me having to run 'ceph cephadm osd activate <host>' as documented in [1]. Zac improved the docs just last week, is that obsolete now? Or is that version specific? A few weeks ago we reinstalled our own Ceph servers as well, but we still run Pacific 16.2.15, and there I had to issue the OSD activation manually. Can anyone confirm this? Thanks!
