[SOLVED] Need some advice for setting up multinode HA cluster

I want to setup a multinode HA cluster.
I've completed OS and PVE installation and configured separate networks; this results in the following /etc/hosts:
root@ld3955:~# more /etc/hosts localhost.localdomain localhost ld3955.example.com ld3955

# The following lines are desirable for IPv6 capable hosts
::1 localhost ip6-localhost ip6-loopback
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters

# corosync network hosts ring1 ld3955-corosync1 ld3976-corosync1 ld5505-corosync1 ld5506-corosync1 ld5507-corosync1 ld5508-corosync1 ld4257-corosync1 ld4464-corosync1 ld4465-corosync1

# corosync network hosts ring2 ld3955-corosync2 ld3976-corosync2 ld5505-corosync2 ld5506-corosync2 ld5507-corosync2 ld5508-corosync2 ld4257-corosync2 ld4464-corosync2 ld4465-corosync2

# ceph cluster network hosts ld3955-ceph ld3976-ceph ld5505-ceph ld5506-ceph ld5507-ceph ld5508-ceph ld4257-ceph ld4464-ceph ld4465-ceph

What is the appropriate command to setup PVE cluster on (first) node ld3955?
How must I add all other nodes to this cluster?
Please advise.

In my understanding this command is wrong: pvecm create pveclstr01 --ring0_addr --ring1_addr

I managed to add all nodes to the cluster successfully using this command:
pvecm add ld3955-corosync1 --ring0_addr 172.16.0.x --ring1_addr 172.16.1.x

root@ld3955:~# pvecm status
