Ok first start fdisk
volumio@volumio:~$ sudo fdisk -c /dev/mmcblk0
Then type ‘p’ then enter this should give you something similar to this:
[code]Command (m for help): p
Disk /dev/mmcblk0: 16.0 GB, 16012804096 bytes
4 heads, 16 sectors/track, 488672 cylinders, total 31275008 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00043284
Device Boot Start End Blocks Id System
/dev/mmcblk0p1 * 2048 155647 76800 b W95 FAT32
/dev/mmcblk0p3 155648 31275007 15559680 83 Linux[/code]
In my case it’s partition 3 that I need to delete (because of the name mmcblk0p3 and it’s the linux partition). If you are unsure post the printout of the ‘p’ command. Write down the ‘Start cylinder’ of the partition you need to expand.
Delete the partition using the ‘d’ command, then enter your partition number
Command (m for help): d
Partition number (1-4): 3
Create a new one by entering ‘n’ then press enter, ‘p’ since you want a primary partition, enter the same partition number you had before (in my case 3). Enter the first cylinder (the one you wrote down). then press enter. Press enter again to select the default cylinder (last one). It should look like this:
Command (m for help): n
Partition type:
p primary (1 primary, 0 extended, 3 free)
e extended
Select (default p): p
Partition number (1-4, default 2): 3
First sector (155648-31275007, default 155648): 155648
Last sector, +sectors or +size{K,M,G} (155648-31275007, default 31275007):
Using default value 31275007
Type ‘w’ to write the new partition table (this won’t modify the actual data on disk, just the information for each partition, so if you keep the printout from the beginning you can always recover using a linux live cd and performing the same steps)
Reboot the Pi, run the following command (make sure to match the partition number you created):
sudo resize2fs /dev/mmcblk0p3
Let me know how it goes!
