Since about 12 o clock, 2 nodes shows to be offline. But the maschine is running. Any ideas?

pvecm status shows all 3 nodes.

All VMs seems to be online..

Hi,

the error with no home dir is not normal.
I think this is the source of your problems.
Did you change some system files?
 
Hi,
we are running a proxmox cluster for near a year without trouble (also an upgrade from 3.4 to 4.1)
Last august we have upgraded successfully the cluster to 4.2-17 from previous 4.1.
From that time in two months we have experienced four trouble very similar to the one described above.
We have 6 nodes configured, up, votes therefore in goog shape apparently.
The web interface show all the nodes red but the one that logged in.
Furthermore there is no way to manage the running vm from the web interface.
We have used the usual cli command
systemctl restart pvedaemon
systemctl restart pveproxy
systemctl restart pvestatd
but the commands hang.
Today we have a new trouble with the same symptoms.
Previously we have decided finally to reboot the entire cluster to restore gui control but the user are very unhappy to stop working for 1-2 hour waiting for orderly reboot.
We suppose the problem it's related to the shared filesystem but we don't have found the root cause or a resolution method.
Can you suggest any ideas to solve the problem ?

Gui: red all node but one logged in; don't manage the running vm

I have the same problem, and i think it's corosync. Now i use ugly workaround via Ansible (note to "pkill -9 corosync):

---

- hosts: pve
sudo: yes

tasks:

- name: Stop pve-cluster
service: name=pve-cluster state=stopped

- name: kill corosync
shell: pkill -9 corosync

- name: Restart pve
service: name={{ item }} state=restarted
with_items:
- pve-cluster
- pvedaemon
- pvestatd
- pveproxy
Click to expand...
 
Is there a methode to restart corosync?

If the cluster think the server is offline to resync? - Actually i have to restart the whole server.
 
Just to let you know.. I have this problem as well.

That command did not bring the server back but it synced all data between them.

I can bring the server back by this command service pvestatd restart.

Server will be back online a while then it goes to offline status.
 
Confirming issue. Lost comunication - even nagios checks against snmpd was unresponsive. Pvecm nodes/info was showing all is ok. Corosync's restart synced, pve-cluster restarted, there was some "endpoint not connected" messages, so i fully restarted server.
