How to increase partition size?


My Linux virtual machine running on XEN and increased 1GB hard disk space.

Current snapshot:

[root@linuxtest01 ~]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/hda3 6.8G 2.3G 4.2G 36% /
/dev/hda5 3.0G 69M 2.7G 3% /tmp
/dev/hda2 6.8G 3.6G 2.9G 55% /var
/dev/hda1 251M 16M 222M 7% /boot
tmpfs 496M 0 496M 0% /dev/shm
[root@linuxtest01 ~]#

Parted command output is showing the added 1GB space:

[root@linuxtest01 ~]# parted
GNU Parted 1.8.1
Using /dev/hda
Welcome to GNU Parted! Type 'help' to view a list of commands.
(parted) print

Model: QEMU HARDDISK (ide)
Disk /dev/hda: 22.5GB
Sector size (logical/physical): 512B/512B
Partition Table: msdos

Number Start End Size Type File system Flags
1 32.3kB 271MB 271MB primary ext3 boot
2 271MB 7789MB 7518MB primary ext3
3 7789MB 15.3GB 7518MB primary ext3
4 15.3GB 21.5GB 6161MB extended
5 15.3GB 18.5GB 3224MB logical ext3
6 18.5GB 20.7GB 2147MB logical linux-swap


How to add the extra 1GB space to / (root) partition (i.e. /dev/hda3)? Please guide me.

Thanks in advance.

I recommend that you boot your VM from System Rescue CD. The process should be similar to however you installed Linux on your VM, assuming you installed from a CD-ROM or an ISO. I have never used XEN, so I cannot give you the exact steps.

Once you have booted System Rescue CD, use partimage to create an image of each partition (except the swap partition). Then create a new VM with the desired hard drive size. Boot the new VM using System Rescue CD and use partimage to restore the image. When you reboot the VM, you should see a larger hard drive.
