extend ubuntu partition in VM

Question

I have Ubuntu as virtual machine guest hosted in esxi server. The Ubuntu disk storage was 5 GB and I wanted to extend the disk up to 30 GB. I extended it via esxi client, and now I see this in Ubuntu terminal

root@linux:/temp# df -h
Filesystem            Size  Used Avail Use% Mounted on
/dev/sda1             5.6G  5.3G   31M 100% /
none                  497M  184K  497M   1% /dev
none                  502M     0  502M   0% /dev/shm

none                  502M     0  502M   0% /lib/init/rw

Partition table entries are not in disk order

How can I extend the sda1 to full 32 GB as showed in fdisk -l output ?

I tried to boot from gparted and can see following

I the sda1 cannot be resized, any help?

Answer 1

This is similar to a situation where you have a larger disk, without having a extended the partition to use the available space. You will need to use a disk utility of some sort while /dev/sda1 is unmounted.

I would suggest using an .iso version of Gparted on the host which you can mount as a DVD drive on the Ubuntu guest. Boot the VM into the Gparted disk, with Gparted operating in live mode, and extend /dev/sda1 to fill the available space.

Gparted is a fairly easy to use program, with an intuitive interface but there are detailed instructions on its use here.
