Node died, need to re-configure Ceph

[tsumaru720]

Hi
I unfortunately had a node in my cluster die (dead raid), so any pre-existing config is gone.

I used the same name, so before joining to the cluster i did pvecm rm <node>

I've reinstalled the node and re-added it to my cluster, but the Ceph page shows a phantom entry for the old node under monitors, and i cant remove it / add it again

When i try to re-add, I get
monitor address '172.16.0.7' already in use (500)

Does anyone know how to fix this? Thanks

Managed to figure this out I think

• Removed the entries from /etc/pve/ceph.conf for the dead note
• Remove its Ip from mon_host
• ceph osd crush rm nodenametoremove
• ceph mon remove nodenametoremove

Seemed to have fixed the problem, i am able to re-add the node to everything
