Oh, and if you've partitioned the LV inside the guest, you'll also need to resize the partition (BEFORE you do a resize2fs, etc.). There are two ways to do this - the safest is to use parted, which works if you're using ext2/ext3 (and a couple other of the most popular filesystems - reiser, I think). The other method is to delete the partition and recreate it with the extended end points. This isn't quite as safe and requires that 1) you're start point for the partition is exactly the same as it was before, and 2) the partition is the last (or only) one on the LV.

I tried to resize a disk of my data guest from 100 to 400 GB.

I started the Guest and did an df -h to check the size but there are still
100 G :( Can somebody tell me whats wrong? i dont want to lose my data at the Disk!
The Machine is Debian Lenny and the guest OS also.

The container is bigger but the filesystem isn't. Resizing an LV doesn't make the FS any bigger.
Log into the DomU and do a resize2fs <device>. You can do this while it's mounted as long as the filesystem is getting bigger.

Some people, when confronted with a problem, think "I know, I'll use Windows."
Now they have two problems.
