Node Reset

Procedures for resetting individual nodes or the entire cluster.

Reset a Single Node

Use just talos reset-node — it prompts for confirmation before executing.

just talos reset-node talos-w-01

This runs talosctl reset --system-labels-to-wipe STATE --system-labels-to-wipe EPHEMERAL --graceful=false. Only STATE and EPHEMERAL partitions are wiped; the OS installation remains. The node reboots into a clean state and can be re-configured with apply-node.

For worker VMs that hang during reboot (kernel RBD stall), hard-reset via Proxmox: qm reset <vmid>

Full Cluster Reset

Wipes all nodes completely (OS disk included). Use this only when rebuilding from scratch.

Step 1: Reset all nodes

# Control planes
talosctl -n 10.10.99.101 reset --graceful=false --reboot
talosctl -n 10.10.99.102 reset --graceful=false --reboot
talosctl -n 10.10.99.103 reset --graceful=false --reboot

# Workers
talosctl -n 10.10.99.201 reset --graceful=false --reboot
talosctl -n 10.10.99.202 reset --graceful=false --reboot
talosctl -n 10.10.99.203 reset --graceful=false --reboot

After reset, each node's disk is completely wiped. Nodes will reboot but cannot boot from disk.

Step 2: Boot nodes from Talos USB/ISO

Each node must boot from a Talos installation ISO to get back to maintenance mode. Download the correct image for each schematic:

just talos download-image v1.12.6 controlplane   # for CPs
just talos download-image v1.12.6 worker         # for workers
just talos download-image v1.12.6 gpu            # for talos-gpu-01

Flash to USB and boot each node. For worker VMs on Proxmox, attach the ISO in the VM's CD drive and set boot order to CD first.

Step 3: Re-bootstrap

Once all nodes are in maintenance mode, run the full bootstrap:

See Bootstrap for full stage details.

Rebooting a Node

just talos reboot-node talos-cp-01

Uses powercycle mode (graceful shutdown + power cycle) with a confirmation prompt.

Shutting Down a Node

just talos shutdown-node talos-cp-01

Health Check

just talos check-cluster-health

# Or directly
talosctl health --nodes 10.10.99.101

Dashboard

just talos open-dashboard

Opens an interactive Talos dashboard for the first control plane node.
