[Hotfix] customer staging cluster

We had to adjust test04 mysql partition, because we were running out of disk space on th mysql partition. So Denny changed this partition to btrfs with compression. This option already runs on test05 without any problems since a week and shouldn't cause problems on test04 as well. -- -- Sören Pestner - Entwickler - TraSo GmbH Nonnenstraße 42 D-04229 Leipzig telefon: +49 341 355 740 - 49 email: s.pestner@traso.de Geschäftsführer: Haiko Gerdes Handelsregister: Amtsgericht Leipzig (HRB 21850)
