Utilizar Ceph con Proxmox (EN)

This guide shows you how setup the Ceph configuration on proxmox.


Fist of all, you need a Ceph cluster already configured. Create the pools, users and set the rights and network ACL.

You also need a proxmox, this documentation is made with proxmox 4.4-13

Storage setup

We edit the file /etc/pve/storage.cfg to add our Ceph storage

rbd: rbd-ceph
        content images
        krbd 0
        pool rbd
        username admin
  • monhost is the ip of our monitors
  • content is the content we want to host on ceph
  • krbd 0/1 if you want to use the kernel or librbd to use the Ceph cluster
  • pool is the pool that will be used to store data
  • username is the username that will be used to connect to the cluster

Keyring setup

Our cluster is now in configuration, but proxmox can't auth yet, we have to add the keyring.

We have have to edit the file /etc/pve/priv/ceph/.keyring, where STORAGE_ID is the name we used in our storage.cfg, here it's rbd-ceph.

root@proxmox:~# cat /etc/pve/priv/ceph/rbd-ceph.keyring
        key = KLChQNJYQJCuXMBBrbsz2XllPn+5+cuXdIfJLg==

Update Ceph packages

Proxmox uses some old Ceph packages, we'll add the official repositories to use the lastest Ceph packages to use the lastest features. We first need to add the keys.

wget -q -O- '' | apt-key add -

Then add the repository.

echo 'deb jessie main' > /etc/apt/sources.list.d/ceph.list

Update repositories.

root@proxmox:~# apt update

Upgrade packages.

root@proxmox:~# apt upgrade ceph-common

You can check the version intalled.

root@proxmox:~# dpkg -s ceph-common
Package: ceph-common
Status: install ok installed
Source: ceph
Version: 10.2.6-1~bpo80+1

You can now see your cluster info using proxmox web interface and create VM on this storage.
