If Ceph is installed locally on the Proxmox VE cluster, the following is done automatically when adding the storage. |
If you use cephx authentication, which is enabled by default, you need to
provide the keyring from the external Ceph cluster.
To configure the storage via the CLI, you first need to make the file
containing the keyring available. One way is to copy the file from the external
Ceph cluster directly to one of the Proxmox VE nodes. The following example will
copy it to the /root directory of the node on which we run it:
# scp <external cephserver>:/etc/ceph/ceph.client.admin.keyring /root/rbd.keyring
Then use the pvesm CLI tool to configure the external RBD storage, use the
--keyring parameter, which needs to be a path to the keyring file that you
copied. For example:
# pvesm add rbd <name> --monhost "10.1.1.20 10.1.1.21 10.1.1.22" --content images --keyring /root/rbd.keyring
When configuring an external RBD storage via the GUI, you can copy and paste
the keyring into the appropriate field.
The keyring will be stored at
# /etc/pve/priv/ceph/<STORAGE_ID>.keyring

Creating a keyring with only the needed capabilities is recommended when connecting to an external cluster. For further information on Ceph user management, see the Ceph docs. |
