====== Resize ext3 partition ======
===== increase partition size =====
when increasing the partition size: increase the partiton size, then increase the filesystem size

ext3 partitions can theoretically be resized with parted with the ''resize'' command but it didn't work in my case, so i used the traditional version. plus parted actually tells you to use other tools for that.. maybe there is something to it :) 


<code>
fsck.ext3 -f /dev/sda1
tune2fs -O ^has_journal /dev/sda1
</code>
use parted or fdisk to delete the partition and create a new one in the desired increased size starting at the same place (DO NOT create a new filesystem!!)
  parted /dev/sda
  print (shows the current beginig and ending of partition)
  rm 1
  mkpart primary START END (end can be -1s to be at the last possible sector of the disk) 
  quit
  resize2fs /dev/sda1
  tune2fs -j /dev/sda1
  fsck.ext3 /dev/sda1

===== shrinking a partition =====
haven't done this yet. 
when shrinking a partiton: shrink the filesystem, then shrink the partition. should be prettymuch the same as above in different order. when using resize2fs pass the new smaller size as second argument

===== post resizing work =====
change fstab and grub conf if necessary. this is especially necessary if partiton id's have changed. see [[harddisks_by_uuid_in_debian_lenny]]
