Issue
VRRP master script does not execute after reboot following initial VRRP configuration.
Steps to Re-Create
- Configure VRRP as below
- On the machine designated as MASTER - run restart vrrp
- On the machine now designated as MASTER - run show log vrrp to confirm script executed with "Running the command: <script name>"
- Repeat as many times to verify as needed
- Reboot current MASTER
- On the new MASTER run restart vrrp
- Go to the new MASTER (this was the machine just rebooted) - script does not execute, not shown in log file
- Delete VRRP configuration entirely on both machines OR remove the transition-script line, add again, save - then everything works again.
- Reboot -> script stops working again
Other
- Script has chmod +x permissions
- Script can be run manually from bash and works

Attaching a screenshot of the script working when keepalived does execute it
