Hi,
I recently cloned an old 5GB linux old HDD to a newer 70GB HDD. I used G4U to clone the image to the new HDD and using this new HDD and throwing out the old 5GB HDD.
My question is that the cloned image set the volume as 5GB instead of 70 GB is there any way I can incrase this volume size so it takes full advantage of this HDD space.
Thanks for reading my email.

That's a consequence of cloning; you copy things bit for bit, including the partition table. But you should be able to increase the partition size nonetheless; but hopefully you've kept that 5G hard drive at least for a little while longer.

First of all, it's always helpful to know what version of Linux you're using, what filesystem, etc.

I'm running Fedora Core 4, with an ext3 partition. Typing "man resize2fs" gives me a little guide to doing this, which basically involves unmounting my partition, starting fdisk, writing down EXACTLY which cylinder my partition starts on, deleting the partition, and re-making it to start on the EXACT cylinder as before. This should then let me then grow my filesystem on that now larger parition.

You should be able to google around for better instructions, but definitely check out the "man" pages on fdisk and resize2fs before getting started.

Of course, if you don't have your old 5G disk anymore, I might recommend doing something a little safer/easier. In Linux, it's relatively straightforward to link together different partitions within the same user-observable filesystem (ie, there's no C: and D: drives to worry about, just folders). So, you could make a new partition on the unformatted 65G, mount that as /home or something, and then you're at least using your full 70G. Check out the manpages for mount and fstab, and things should work pretty well.

Well I am using RHEL AS 4.0 version.
I did it differently with the 5GB HDD now, instead I want to do what I said for a nice 8GB computer unit.
This is the output of df -h:

Filesystem Size Used Avail Use% Mounted on
/dev/mapper/VolGroup00-LogVol00

/dev/sda1 99M 13M 82M 14% /boot
none 252M 0 252M 0% /dev/shm

Disk /dev/sda: 73.3 GB, 73398878208 bytes

Now, how do i make another partition or extend the volume of the current one so it doesnt overflow....
thanks for reading my reply

below process might help you :

1. create a PV on new /dev/sda

#pvcreate /dev/sda2

2. Now extend the existing Vg on this newly create Pv

#vgextend VolGroup00 /dev/sda2

3. Once you make sure its added ( vgdisplay VolGroup00 ) go ahead and increase the size of the LV

#lvextend LogVol00 VolGroup00

4. To confirm

#lvdisplay LogVol00

5. If everything works

#ext2online LogVol00

Hope this helps
