Using gparted and partimage from SysRescCD I recently
- made a backup image of the partition containing my Ubuntu installation,
- deleted all partitions except for the original Windows partitions
- reduced the size of the Win7 partition
- created an extended partition using all unallocated space
- within the extended partition, created an ext3 partition and a swap partition
- restored the backup image to the ext3 partition
After these operations the ext3 partition is larger than when I started, but the filesystem is still reporting the old size:
$ fdisk -l
Disk /dev/sda: 640.1 GB, 640135028736 bytes
255 heads, 63 sectors/track, 77825 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x1549f232

/dev/sda1 * 1 13 102400 7 HPFS/NTFS
Partition 1 does not end on cylinder boundary.
/dev/sda2 13 12772 102487666 7 HPFS/NTFS
/dev/sda3 12773 76258 509947904 5 Extended

/dev/sda5 12773 25597 103010304 83 Linux
/dev/sda6 25597 27016 11395072 82 Linux swap / Solaris
/dev/sda7 27016 59024 257102848 83 Linux
The extended partition /dev/sda3 contains /dev/sda5, /dev/sda6/, and /dev/sda7. The Ubuntu image is on /dev/sda5 - which is the same partition it was originally on. Before the operations /dev/sda5 was 50GB, now it is 98GB.
$ sudo df -h

I'm looking for advice on what I can do to have ext3 on /dev/sda5 utilize the full 98G.
