Cancel a pending reboot in AWS PCS

Cancel a pending reboot to avoid unnecessary downtime when the issue has been resolved or when reboot is no longer needed.

Prerequisites

  • Slurm Admin privileges

  • Node must have a pending reboot (showing "reboot issued" status)

  • Access to login node for command execution

Procedure

  1. Connect to the login node.

  2. Verify the node has a pending reboot using scontrol show node.

    scontrol show node nodename

    Look for "reboot issued" in the node status.

  3. Execute the cancel command.

    scontrol cancel_reboot nodename

  4. Verify reboot cancellation and node status return to normal.

    scontrol show node nodename
