pveceph - removing a node?

[nethfel]

Hi all,

Does anyone have a proper procedure for removing a node from ceph, uninstalling the ceph software but leaving it part of the proxmox cluster? I've got a machine I want to remove from ceph and replace it with another machine, but keep the original machine in the proxmox cluster.

The option you are looking for is : #pveceph purge which will remove ceph from the node but still keep it in the Proxmox cluster. I usually just remove any MON or OSD from the node instead of total purge, incase i need them later. Once MON/OSD removed, Ceph is very much inactive in that node.

Ok, I was concerned about using purge because I thought it might destroy all of my ceph network. That node I was using originally for testing and it really doesn't have enough ethernet ports for what I need to keep it as an OSD system as it was meant to be a VM host (6 ethernet ports total, 1 port management, 2 ports ceph client, 3 ports VM guests, I'd need at least an additional 2 ports for it to be on my ceph private storage network)..
