Hi all,

Ive just been through the ringer - tried to change a node ip which caused a bunch of issues with certs, however, I have split a node off from my cluster and will be using this standalone.

It was orgiinally part of a ceph cluster, and still has all the ceph stuff installed. Whats the best way of basically reverting this separate node to act like ceph was never installed? I really dont want to reinstall as the config was a pita with nvidia drivers etc.

Its weird as the separate node is almost acting like an observer, i get stuff back from ceph -s pertaining to the other cluster but i want them completely separate. Im not able to wipe the osd disk even though it isnt part of the cluster anymore.
