[gentoo-user] help on partitioning

[Fernando Meira]

Hi, I need a quick help for a simple question.

My disk now looks like this:
Filesystem             Size   Used  Avail Use% Mounted on
  /dev/hda1               11G   9.2G   1.4G  88% /
  udev                   264M   242k   264M   1% /dev
  /dev/hda4              4.9G   4.6G   329M  94% /home
  /dev/hda5               25G    21G   3.9G  85% /mnt/share
  none                   264M      0   264M   0% /dev/shm

 where hda5 is an extended part located after hda1 and before swap. At
the ends is hda4.
  All parts are reiserfs unless hda5 which is FAT and I want to get rid of it.

 So what I want to do is to increase the size of hda1 and move some
things around.
 I plan to remove the extended partition, thereby creating space right
after hda1 so that this one can be increased. Then I intend to create
a new swap part of 1Gb right after the new hda1 and use the remaining
space for /home.
So my question is, can I do all this using QTParted? And in a normal
session, without unmouting any partitions, or do I need to boot from a
install-cd?

Any comments on the partitioning are also welcome.

Thanks for your time,
Fernando

Please post the output of 'fdisk -l' run as root. Without this info it's
not really possible to give you a full answer, but I'll still try.

Hmmmm, you want ot re-order those partitions so their number follows the
location on-disk.

No no no no no you do not want to do this.

Without an extended partition you will limit yourself to 4 partitions
total and it is a nightmare to get it back to having an extended
partition. Leave it as is, it does no harm and as far as you the user
are concerned you end up with up to 16 (maybe 64) partitions max.

You do this on the command line with tools like fdisk. QTParted may or
may not be able to do it, I always had uncertain results and have
learned to not trust such gui tools.
