You can remove it with this command:
$ ceph osd crush remove <hostname>
Zitat von Jaep Emmanuel <emmanuel.jaep@xxxxxxx>:
Hi,
I want trying to do some cleanup of a server that has been
forcefully decommissioned.
I manage to remove the OSDs using the manual procedure in the
documentation. However, the host still shows up in the crush map.
I was thinking of the following procedure to remove the host from
the crush map:
```
ceph osd getcrushmap -o /tmp/crush
crushtool -d /tmp/crush -o /tmp/crush_decompiled
vi /tmp/crush_decompiled
```
remove all references of the host.
```
crushtool -c /tmp/crush_decompiled -o /tmp/crush_recompiled
ceph osd setcrushmap -i /tmp/crush_recompiled
```
Is it the correct way to do it?
Is there anything ’safer’?
Best,
Emmanuel
