I have two partitions, a swap (1GB) and a 73GB reiser partition, and want to free up 10 gigs of space by resizing the reiser partition. I dont want to ruin the partition or lose data, so I was wondering how I should go about doing it. Ive heard of a live cd specifically made for partitioning, does anyone know what it is and if it will do what I need, or a quicker way? thanks

Point 1: when you play arround with filesystem/partition, BACKUP YOUR DATA FIRST.
Point 2: read point 1.

Now, to shrink your partition:
- Boot off a cd/rescue disk/usb key containing a working linux system with the reiserfs tools (I guess any knoppix live cd or such has such tools installed). Don't mount your system disks
- Shrink the file system on the given partition with resize_reiserfs
- Using fdisk, shrink the partition the filesystem is on: delete the current partition and make a new one starting at the same block. Don't make the partition smaller than the filesystem.

You're done.

Hint: to make sure you don't mess-up: shrink the filesystem a little more than you really need, shrink the partition to the size you need, and run resize_reiserfs on the device again with no option to expand the filesystem to the full device size (this last operation can be done on a mounted filesystem).
