Proxmox VE VM will not start

Retrying or clearing a lock rarely gets a Proxmox VE VM running. How 2501 finds why it will not start, starts it within your limits, or says exactly what is in the way.

A Proxmox VE VM that will not start is running again after 2501 checks the cluster and the node as well as the VM and applies the fix within your rules, or hands a person what is in the way

SOLUTION_BRIEFING

// HOW 2501 HANDLES IT

When a Proxmox VE VM will not start, retrying or clearing its lock is the quick fix, but a retry meets the same cause, and a lock usually means a task such as a backup is running or stopped halfway. 2501 finds out why before touching anything, then gets the VM running within limits you set, or says exactly what is in the way.

A service is down because its VM will not come back. The cause can sit in its settings, on its node or in the cluster: a cluster that has lost quorum turns read-only and refuses changes, and forcing quorum back by hand is a workaround for experts, not a routine fix.

What 2501 does

The Proxmox VE Cluster Operator finds what is stopping the start, looking at the cluster and the node as well as the VM, so a cluster problem is not mistaken for a broken VM. It tries no fix that needs a healthy cluster while quorum is lost. Where the fix is within your rules, it applies it, starts the VM and confirms that it is running. Otherwise it stops and hands a person what it found, the issue blocking recovery and the exact next step.

How 2501 handles a Proxmox VE VM that will not start: signal, check the cluster and the node as well as the VM, apply the fix within your rules and start the VM, confirm it is running or hand a person what is in the way and the next step

You stay in control

  • You choose the level: investigate only, act after a person confirms, or act on its own within your rules. The level is set per specialty, not per ticket.
  • Nothing is destroyed: it never deletes a VM or container, and never restores a backup over an existing VM without approval.
  • The cluster itself waits for a person: changing quorum, removing a node or switching off high availability always needs a person's confirmation.
  • Your rules apply: which nodes and VMs are in scope, and blacklisted commands stay out of reach, whatever a ticket asks for.

Frequently asked

Will it clear the lock on a stuck VM? Not blindly. A lock is set by a task such as a backup or a migration, so it finds out why before clearing it.

What about a single Proxmox VE node? The CLI Operator works on the node itself and the API Operator through the Proxmox API. Both start a stopped VM when the ticket asks.
