Don’t you rather want to use 'systemctl disable'? And maybe out comment the fstab entry, just to make sure. -----Original Message----- From: Brett Chancellor [mailto:bchancellor@xxxxxxxxxxxxxx] Sent: woensdag 28 augustus 2019 3:28 To: Cory Hawkless Cc: ceph-users@xxxxxxx Subject: Re: Best way to stop an OSD form coming back online If you just destroy the osd, it won't change the crush weight. Once the drive is replaced you can recreate the osd with the same OSD.

The server is in the datacentre and I won’t get there for a few weeks so I’ve stopped the service (systemctl stop ceph-osd@208) and let the cluster rebalance, all is well. My thinking is that if for some reason the host that OSD208 resides within was to reboot, that OSD would start and become part of the cluster again. So I’d like to prevent this OSD from ever starting again without physically being able to remove it from the server. I was thinking that deleting it’s key from the auth list might work. So a ceph osd purge 208 Then when the service tries to start it’ll fail with an auth error. Any other suggestions?
