[pve-devel] [PATCH v2 storage 2/2] Ceph: add keyring parameter for external clusters

Aaron Lauterer a.lauterer at proxmox.com
Tue Aug 3 13:45:56 CEST 2021


By adding the keyring for RBD storage or the secret for CephFS ones, it
is possible to add an external Ceph cluster with only one API call.

Previously the keyring / secret file needed to be placed in
/etc/pve/priv/ceph/$storeID.{keyring,secret} manually.

Signed-off-by: Aaron Lauterer <a.lauterer at proxmox.com>

changes since v1: add check if the keyring parameter exists before
deciding on whether to store or remove the file.

thx @thomas for catching that
