The main cluster issues

This section contains issues related to the main Proxmox's cluster operations.

Issue – Proxmox virtual machines are running, but the Proxmox GUI shows that everything is offline

This is usually caused by one of the three services, such as pvedaemon, pvestatd, or pveproxy crashing or stopping working for any number of reasons. Simply restarting them through SSH will fix this issue. One of the common causes of this issue is if any NFS shared storage gets stuck during an extended backup task. A node reboot will always fix this issue. But reboot is not always possible in a production node. Forcefully unmounting the NFS shared storage under /mnt/pve/<share>, then running the following commands will show everything normally again:

# service pvedaemon restart
# service pveproxy restart
# service pvestatd restart

Issue – kernel panic when disconnecting USB devices, such as a keyboard, mouse, or UPS

There is no real solution to this issue yet, as the issue is not reproducible...
