How to use ISPConfig and Seafile without manual file modifications

Seafile is an open-source cloud based file storage system similar to Dropbox & Box. The difference is that Seafile can be deployed on a client's own system.

Debian Wheezy: Split and resize Xen disk image

Background

One of my Xen virtual servers needed to have its 400G disk split and resized over the weekend, and I wanted to keep downtime to a minimal. The disk had 240G used, 235G of which was a /backup directory, and the remaining 5G dedicated to a regular Debian Linux installation. I wanted to split the disk into a two disks - a 20GB disk containing the Linux system, and a 300G disk to mount as /backup. Then I could apply my DRBD setup to replicate that 300G backup partition to a separate 2nd backup machine.
