I've got a CentOS install on a 80 GB HDD of which only a few GB is used for the current CentOS install.

is there a way of spitting that hard drive into 2 40GB partitions in able to isntall anotehr Linux distro without killing the current CentOS install and doing it all over?

Here you go...

1) If you have partition fully with 80G with existing OS without LVM. less chance ..if you partioned with LVM there is chance to resize and format the exess space...

2)elseif you have partioned only few GB for existing OS then YES u can use free space for next ...

Let me know how can i help you ??

Yes, a default installation creates 2 partitions, boot and a LVM for root(/) and swap. Actually, it would be easier to resize existing partitions if they are not LVM.

Thanks, I've used the default install but used all of the 80GB (ksdeiva's option 1).

Howto from here?

ok fine !

1)if its in LVM here you go by below procedure.

First Step : –> umount /lvmpartition
Second Step : –> e2fsck /lvmpartition
Third Step: –> resize2fs /lvmpartition
Fourth Step: –> lvreduce -L100M /lvmpartition
Fifth step –> resize2fs /lvmpartition
Sixth Step : –> mount /lvmpartition

2) if not in LVM no ways...

Not true. gparted is capable of resizing existing partitions not associated with a LVM but you should boot the computer using a live CD.

Make sure you backup any and all important data just in case.
