Re: Resizing EXT3 partition in guest instance CentOS5

Yes, it will, works all the time with me but using SysrescueCD. But don't forget to backup your data before the resizing, any operation with disk partitions may lost data.

Hi,

I have two guest vm instance running CentOS 5 with ext3 partition. I will like to reduce 1 VM harddisk space and using the 'release' harddisk space to add onto my second VM. Basically I need to know how can I reduce and increase an ext3 partition in CentOS KVM. I did a search and basically i can do it by booting the VM using Knoppix and use Gparted to reduce and increase the diskspace. I am thinking of the following

1) Boot first VM using Knoppix

2) Reduce the ext3 partition disk size using Gparted

3) Shutdown the VM and resize the diskspace using Virtual Manager

4) Increae the diskspace of the second VM using Virtual Manager

5) Boot up second VM using Knoppix

6) Increase the ext3 partition disk size using Gparted

7) Reboot the second VM

As this is the first time i am doing it, will these work? Anyone has experience resiziing their EXT3 partition in KVM environment before?

Thanks!

Regards

yongsan
