Configure hosts file Proxmox VE6 cluster

[Hoang.NV]

Hi everyone,

When I create cluster with 3 nodes (node01, node02, node03) via GUI Proxmox VE6, file hosts on each node is like:
----
127.0.0.1 localhost.localdomain localhost
192.168.1.1 node01.domain.vn node01 # only node01's IP not contain node02, node03


# The following lines are desirable for IPv6 capable hosts

::1 ip6-localhost ip6-loopback
fe00::0 ip6-localnet
ff00::0 ip6-mcastprefix
ff02::1 ip6-allnodes
ff02::2 ip6-allrouters
ff02::3 ip6-allhosts
----

Above hosts file is OK ? As i know file hosts on each must include IP of three nodes for reference all nodenames (names resolvable).

Thanks.

Hi Hoang,

for pvecm it is not necessary to have entries for the other nodes in the hosts file, the important thing is that the IPs in /etc/pve/corosync.conf are correct. If you want other services to be able to resolve the node names then yes, you can just add the entries for the other nodes to each hosts file.

Best Regards,
Fabi
