Since there is no PV fedora-ostree-content-volume-2 on stg
the volumeName: "fedora-ostree-content-volume-1" was added.
We use ocs-storagecluster-cephfs to keep the ReadWriteMany
functionality. If the RBD volume is required,
then use storageClassName: ocs-storagecluster-ceph-rbd.
ODF will provision a new volume automatically.
ReadWriteMany cannot be used in a Filesystem mode with RBD.
