There is no need IF you setup your system sensibly.

It has always been standard advice to put "expanding stuff" like log files on a different filesystem to your OS. With Myth, it's further advised to put your recordings on their own filesystem - and in any case never ever on the same filesystem as your OS or DB.

If you follow this advice, the very worst that can happen is that you fill your recording drive, the recording stops, and further recordings fail until you free up some space. It won't destroy your DB, it won't stop the system working, in short it won't cause any damage other than truncated and/or failed recordings.

Ignore this advice, as it seems you have, and when a recording goes wrong (or something goes manic with logging, etc) then your disk fills, MySQL crashes and damages your database, and your system falls over.
