"pveceph purge" error with unable to get monitor info

[rudysp]

Hi,

I need to clean reinstall Ceph Cluster while also changing the Cluster IP and Public IP. After stopping and outing OSD, remove MON and cleaning up all file, folder, services and do apt remove i cannot proceed to "pveceph purge" with message "unable to get monitor info from DNS SRV with service name: ceph-mon".

Any suggestion what i might be missed?

"pveceph purge" with message "unable to get monitor info from DNS SRV with service name: ceph-mon".

The last monitor is a bit tricky to remove, i.e., almost impossible without getting ones hands dirty..

Often it'd be enough to keep ceph installed and just re-setup it. One can also change public, clöuster networks on the fly on a installed cluster..

@rudysp I have exactly the same mess. Did you fix it?

I end up reinstalling the whole cluster as however those was still in a lab env. But the lesson learn is we need to follow guidance and do it properly while removing or destroying part of the cluster without the pain afterwards.

Exactly not what I wanted to read. I ended up in doing the same..
