Hi,
**********************************************
I will not be responsible for consequences because of any mistakes that
you make. I have warned you. If you don't know what you are doing then
don't do it.
**********************************************
If you give me your harddrive partition layout. I will give you the list
of commands.
Read each and every line in the email carefully. One mistake will screw up
your entire file system.
YOU WILL NEED YOUR ORIGINAL LINUX CD(Redhat/SUSE/Debian/Fedora) Does not
matter they all have rescue mode. I mean it.
Boot from the your Distro CD by selecting the RESCUE mode.
Note You will be entering the rescue mode. not the installation mode. and
do not mount any of your filesystem. Skip it.
It is not trivial but here is the list of steps you would follow.
Make a full backup.
Here is the step you would follow.
To shadow your file system
1. acquire another harddrive, (if you don't have one then allocated
another partion on the same harddrive at a safe distance will will not
overlap with your resizing process)
Make a partion, format and mount it
I am assuming you will mount thet at /backup
and your root will be mounted at /rootdisk
2. then
(cd /; tar cf - rootdisk ) | (cd /backup; tar xf - )
This will shadow your entire hard drive this can be later on used to boot
your system even if you screw your original system.
So it is your only rescue.
Now umount both file systems.
Here is the brief info for resizing.
fsck -f /dev/hda1 make sure your file system is intact.
1. fdisk -l /dev/hda
print this info ( I mean it)
Disk /dev/hda: 163.9 GB, 163928604672 bytes
255 heads, 63 sectors/track, 19929 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/hda1 1 249 2000061 82 Linux swap
/dev/hda2 * 250 2740 20008957+ 83 Linux
/dev/hda3 2741 19929 138070642+ 83 Linux
Above is my harddrive, for me the first if the swap, yours may be different.
here make sure you are having the info for Start/End cylinder info. This
is very important. Otherwise you will screw the entire system.
I am going to assume that your going to merge hda2 and hda3
2. Now delete hda3 and hda2
3. create a new partition of desired size. you cannot shrink it(even
though it is doable, you may lose your data, Since I already see your
first partiion is close to full). Let me say you have 40GB hard drive
first one is the root and the second is the swap. remove the swap also.
basically you will be deleting all the partitions on the harddrive and you
will have to move your swap to another area. You cannot move your root
partition you can only resize it.
Let us say you want to make it 20GB, Then from within fdisk delete all the
partition.
The new partition should start from where your old root partition started
Like in my case it is 250 then let the end be at +20480M
Now create your swap may at the end of the harddrive at 19650 to the end
of of the harddrive like 19929.
now set the partition type for the root and the swap.
then do mkswap on /dev/hda2 ( assuming this will be your swap)
Then Now
resize2fs /dev/hda1 (this will take a while)
That is it.
No your root partition has 20GB allocated.
