Replication factor 3 can be configured if both controllers are unlocked (controller-1 can be in degraded)
On storage system 2+2+X deployment
Unable to modify replication factor if the storage nodes are installed already
$ system storage-backend-modify ceph-store replication=3 min_replication=2
Can not modify ceph replication factor once a storage node has been installed. This operation is not supported.
If storage nodes are not installed, both controllers are needed
[sysadmin@controller-0 ~(keystone_admin)]$ system storage-backend-modify ceph-store replication=3 min_replication=2
Storage backend operations require both controllers to be enabled and available/degraded.
On a simplex system the replication factor can still be modified if the host is locked
$ system storage-backend-modify ceph-store replication=3 min_replication=2
Storage backend operations require controller host to be locked.
