Description

Right now (without any docs), this is totally confusing.

Topics to cover:

Man page

overview

  • cephadm ... is a tool for managing the local host. (Not a daemon)
  • Even usable, if the Ceph clusterdoes not know about a host

Removing a daemon

Don't use `podman rm -f` to remove daemons. Instead use `cephadm ..`

Remove the cluster from the local host

fsid=$(cephadm shell -- ceph fsid)
cephadm rm-cluster --fsid $fsid
