Proxmox CLI

This is to be a list of various CLI commands or scenarios for either automation or if for some reason the GUI is unavailable or unresponsive.

Config

Configs are stored in /etc/pve, while direct editing of these files is not recommended or supported the information in these files can be useful in an emergency situation or when the GUI is unavilable / unresponsive.

• In cluster setups this is a fuse mount-point managed by the corosync process.
• Loss of quorum can make this mount point read-only.

VMs

VM is locked

Problem: can’t lock file ‘/var/lock/qemu-server/lock-.conf’ – got timeout or `VM is locked (backup|snapshot|clone|etc)`

Solution 1: qm unlock <VMID>

Solution 2: rm /var/lock/qemu-server/lock-<VMID>.conf

Containers

LXC

Directory mapping:

Directly mapping a directory from the host into a LXC container (similar to a docker bind-mount). While not great from a cluster it is useful

https://pve.proxmox.com/wiki/Linux_Container#_bind_mount_points https://forum.proxmox.com/threads/mount-host-directory-into-lxc-container.66555/

# Add the following to /etc/pve/lxc/<container_id>.conf
# Requires a reboot to activate
mp0: /mnt/nas0/,mp=/nas0

or

# Does not require a reboot, is immediate.
pct set 102 -mp0 /mnt/nas0/,mp=/nas0/
