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 Device Boot Start End Blocks Id System /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/sda4 76258 77826 12591104 7 HPFS/NTFS /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 Filesystem Size Used Avail Use% Mounted on /dev/sda5 50G 46G 2.3G 96% / none 2.9G 276K 2.9G 1% /dev none 3.0G 2.1M 3.0G 1% /dev/shm none 3.0G 372K 3.0G 1% /var/run none 3.0G 0 3.0G 0% /var/lock none 50G 46G 2.3G 96% /var/lib/ureadahead/debugfs /dev/sdb1 597G 170G 427G 29% /media/My Book__ /dev/sda7 242G 8.2G 221G 4% /media/012583af-4e10-4bec-84b2-d691c3fd5f96
I'm looking for advice on what I can do to have ext3 on /dev/sda5 utilize the full 98G.
