Hi , not a solution, just a question/observation regarding your solution.

Considering how large your logs are already, how much more will they grow,
and at what rate?

Your solution, although a lot more elegant than just increasing volume
space, would potentially have the same issue down the line, which would
then require more time to solve the same issue again.

Is that really thus a good solution? Not dissing your idea, and some good
thinking out the box, but sometimes staying within the box is better ;)
