Some months ago I decided to switch from gentoo to debian. Since I still had an old partition for ubuntu I just installed debian there.

While sitting in the Hackcenter¹ I decided to repartition my hard drive. I didn't need gentoo anymore and the unencrypted swap was also pretty useless, but they ate nearly fifty percent of my disk space! So I decided to delete them and resize my home-partition. Here is how I did it:

1. delete the partitions for gentoo (use parted or whatever)
2. fdisk-> delete debian partition (it's sda6 for me) and recreate partition, now including free space after the old one²

the following steps can be done on the running system (yay!):

1. resize crypted volume (expands automatically to the maximum)

   cryptsetup resize /dev/mapper/sda6_crypt

   maybe I did a
   

   pvresize alles

   to resize the lvm group "alles" - I don't know
2. resize your logical volume - 7202 is the number ob blocks that can be added. Choose a big number and lvresize will tell you how many blocks you can add.
   

   lvresize -v -l +7207  /dev/alles/home

   resize the filesystem

   resize2fs /dev/alles/home 

you're done!

Update: There are really people who read this (via google) and I would like to know whether it worked for you. So please comment! (update2: no comments with ikiwiki, send me a mail if there's something you want to know)

1: at the 24C3, it was great btw.

2: you can't use parted because parted tries to resize the filesystem too and there it fails
