While upgrading multiple VyOS instances I hit config file corruption again.
I checked if the config was correct before doing a reboot and it was fine.
I have 3 remarks about this:
- It seems like you need a little uptime before this happens. Going back and retrying the upgrade gives no problems
- Maybe unrelated, but on another lab router I had database corruption in a container after an upgrade. These were also corrupted files on the filesystem.
- Also, when rebooting, the /usr filesystem is not unmounted and throws an error.
I have to upgrade another router with a bigger uptime. Before upgrading I will remount the FS in sync mode to see what happens.
