I mounted a second (VDI Virtualbox fixed size) disk to CentOS. Both disks are now ± 100GB.

CentOS is complaining my disk is full, when I had a look it looks like I didn't use the second disk, but just split my primary disk in two.

Disk two was created to put some backups on, so only /backup should be on disk two. The primary disk can be cleared out so my home folder has 50GB more space.

I don't know how to do so without removing my data.
