Remove osd from configuration database

[ColinDexter]

I have a node in my cluster (last version) that has crashed. Now I'm removing it from my cluster so that I can install a new one later with the same name.

I removed the node from ceph with:
ceph mon remove <mon-id>
ceph osd purge {id} --yes-i-really-mean-it

However, the OSD of the deleted node still remains under ceph > configuration under configuration Database.


The question is how do I get this away. It is gone from the monitor, from the configuration and also from the crush folder.

You could ignore this, if osd.1 will be the same device later after reinstall. Otherwise you can remove the config entry with:

root@PMX4:~# ceph config-key ls
root@PMX4:~# ceph config-key del config/osd.9/osd_mclock_max_capacity_iops_ssd
key deleted

Dont forget to remove the host from your pve-cluster according to the documentation (not freestyle).

Thanks, I'll leave it that way. Because it will be the same device after the reinstall. Yes, I have already removed the host from the cluster.
