[CDash] cleanup space

[Fabian Wein]

My cdash 2.6 server is running out of diskspace with the database cdash4simpletest and there the file test.ibd
consuming most data.

On the webfrontent in CDash maintenance Cleanup database and Compress test output has no effect but probably I already have not sufficient space left.

What can I do?

Even loosing all data but not having to setup all everything again would be a helpful worst case approach.

Thanks,

Fabian
