Subject: [PVE-User] Nodes lose connection to master
Hello,
we have a cluster of three nodes:
mox-110 (slave)
mox-114 (master)
mox-118 (slave)
[Martin Maurer]
There are no master and slaves in Proxmox VE 2.x.
Yesterday morning all three nodes shown in syslog: "crit: cpg_send_message
failed: 9".
After opening the WebGUI of one node after the other, only the active node was
shown
as online the others were shown as offline.
At evening I restarted the master and the error disappeared in his log.
At the slaves the syslog entry "crit: cpg_send_message failed: 9" was visible
again.
But the master recognized changes at the pve-worker processes.
รจ I restarted the slaves and everything went back to normal.
The problem resulted in my opinion by a malfunction of the pve-cluster service.
[Martin Maurer]
I assume it's a network communication problem. Any firewall on your hosts? Is
IP multicast supported in your network environment?
Martin
Is there any way to prevent this from happening again?
Greetings
Steve
