Comment 10 for bug 1827080

This issue is side effect for patch: https://review.opendev.org/661900 for LP: 1827119, sorry for that.

The root cause is in function: check_node_ceph_mon_growth(), when add new ceph monitor, the parameter: cgtsvg_growth_gib should be 0, but in current implementation, it default value is ceph_mon_gib and cannot satisfy the condition with check_node_ceph_mon_growth() and raise error messages which block ceph-mon-add operation.

To resolve it, we should make sure the cgtsvg_growth_gib == 0 when new ceph monitor is created, I will soon raise another fixing patch for it.
