Resize Debian in VirtualBox
- by Poni
I have a VM with one HD of size 3GB and I'd like to enlarge its HD to 7GB.
So I execute this command on the host (while guest is shutdown):
VBoxManage modifyhd debian.vdi --resize 7168
Then I run the guest, Debian 6, and then:
smith@debian6:~$ df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda1 2.8G 2.6G 60M 98% /
tmpfs 61M 0 61M 0% /lib/init/rw
udev 57M 160K 57M 1% /dev
tmpfs 61M 0 61M 0% /dev/shm
smith@debian6:~$ sudo parted /dev/sda print
Model: ATA VBOX HARDDISK (scsi)
Disk /dev/sda: 3221MB
Sector size (logical/physical): 512B/512B
Partition Table: msdos
Number Start End Size Type File system Flags
1 1049kB 3035MB 3034MB primary ext3 boot
2 3036MB 3220MB 185MB extended
5 3036MB 3220MB 185MB logical linux-swap(v1)
smith@debian6:~$ cat /proc/partitions
major minor #blocks name
8 0 3145728 sda
8 1 2962432 sda1
8 2 1 sda2
8 5 180224 sda5
So, no automatic resizing (detection) of the HD/partition (while VirtualBox, in the host, shows it's 7GB now). Ok...
Then I do:
smith@debian6:~$ sudo resize2fs /dev/sda1
resize2fs 1.41.12 (17-May-2010)
The filesystem is already 740608 blocks long. Nothing to do!
smith@debian6:~$ sudo parted

WARNING: you are attempting to use parted to operate on (resize) a file system.
parted's file system manipulation code is not as robust as what you'll find in
dedicated, file-system-specific packages like e2fsprogs. We recommend
you use parted only to manipulate partition tables, whenever possible.
Support for performing most operations on most types of file systems
will be removed in an upcoming release.

Here I'm stuck. At the above parted it asks me to resize to 3GB. No point in that, right..
What should I do in order to enlarge this partition?
