I did not want to rebuild the SSD In this example Proxmox 6.3, Ceph Octopus (15.2) Remove the node from Ceph monitors and managers pveceph mon destroy pvetest3 pveceph mgr destroy pvetest3 Now re-install the node After installation finishes add the node back to the cluster (need to remove the old one first)

In this scenario I had Linux installed on a VM with disk size 10G with LVM configuration. I needed to extend the root residing on the LVM on this disk. I resized the disk from the hypervisor (10G->16G), now need to extend the space on the OS
