Hi,

I recently updated our 4 node cluster to 6.2-10 and now the WebUI is broken.
I can login but I can't get VM Names, Host Status or CLI.
There's also a load of Error 501's show in the browser web console.

Other functionality seems to work though.

Checking with htop via ssh pmxcfs is taking up a lot of CPU but this might be normnal?

pvesh get /nodes/ via ssh also shows no CPU/Memory usage.

If this isnt a bug, can somebody point me in the right direction?

Hi,

did you restart nodes after upgrade? - if so please cold-restart as well, if not work please post output of pveversion -v
 
A reboot (Rebooted 1,2 and 4) temporarily fixed it and after ~30-60 minutes they all dropped out and refused to migrate and open the shell again.

Hi again,

Can you see if there any error in syslog/journalctl?

also check if all proxmox services are running by this command
Bash: 
pvesh get /nodes/{node}/services/

By GUI Datacenter -> NodeName -> System

All the PVE Nodes show this in the journalctl output (I have since disabled a script that an API polling script we run incase we're DDOS'ing ourselves)

We get the occasional segfault with Ceph but that shouldn't cause issues with PVE.

So I've solved the issue, maybe...

There were a load of pvestatd processes sat there hung; I killed them all and did pvestatd start and everythigns come back.
 
It might have been the graphite stats metric sender, we don't have UDP enabled on the system anymore but had forgotten to remove it from pve/status.cfg

I have now removed it and will see if that solved the problem.

Great!

Please mark the thread as [SOLVED] to help other people who have the same problem Thanks!

Have a nice day :)
 
I had the same problem. Couldn't remember why I configured the /etc/pve/status.cfg. In our case the server entry was configured with a totally wrong server IP. hmmm....

I deleted the /etc/pve/status.cfg und killed all the pvestatsd and gestarted the pvestatsd again.

Look fine now.
