Mastering Proxmox - Third Edition

Issue – a Ceph node is removed from the Proxmox cluster, but OSDs still show up in PVE

This is a common occurrence when a Ceph node is taken offline without removing all the Ceph-related processes first. The OSDs in the node must be removed or moved to another node before taking the node offline. Run the following commands to remove OSDs:

    # ceph osd out <osd.id>    # ceph osd crush remove osd <osd.id>    # ceph auth del osd.<id>    # ceph osd rm <osd.id>
