I was reminded of this by T7812.
A couple months ago, `bin/storage dump` would fail for me with an error about `max_allowed_packet` size. I ended up adding the following to my `my.cnf` to fix this:
```
[mysqldump
max_allowed_packet = 50M
```
Not sure what best solution is here. `bin/storage` could maybe set the option when it calls mysqldump (`--max_allowed_packet=50M`) or it could maybe this could be another setup warning (if the value of this param is even available to the instance).
