- Image SD Card with your favorite tool (I've been using ApplePie Baker)
- See Option 1 and Option 2 below. Option 2 represents what my SD card experience has been with OSMC.
- Basically - fdisk -l to identify partition(s). Delete the partition (or second one if it shows two) and note the start block! Create a new partition and start it with the exact block of the previous one. If you want to use the rest of the SD card (like I did) you can use the default end block. Write and exit. Reboot - space has not been allocated for use yet...run the command "resize2fs /dev/mmcblk0p..." as root and it will allocate the space.

Option 1
Expand partition and filesystem
List existing devices and partitions with
sudo fdisk -l
$ sudo fdisk -l

Partition to resize is
/dev/sda2
make note of Start (122880)
Now run this command:
sudo fdisk /dev/sda
At the prompt (

d
delete partition2
partition to delete i.e /dev/sda2p
to confirm the deletionn
new partition (default)p
primary (default)2
partition number (default)122880 first sector as noted above (N.B. not default)
+50G last sector make size 50Gb (N.B. not default) or take default to use the remainder of the disk
p
to confirm new partition is createdw
writes the partition information, reboot required if the partition was already mounted (as it was in this instance)
After exit, run:
sudo resize2fs /dev/sda2
to expand the file system to fill the new partition
____________________________________________________________________
Option 2
run sudo fdisk /dev/mmcblk0
Then press the keys in order:
d 2 to delete,
n p 2 Enter Enter to re-create.
Verify the prompts to make sure what you are entering is sensible.
Reboot and enter:-
sudo resize2fs /dev/mmcblk0p2
This is similar to the other answer, but using Pi partition names.
There is one thing to be wary of. MAKE SURE the new partition STARTS on the same block! If it tries to create a new partition in the spare 3M you will need to manually enter start block. Runningsudo fdisk -l /dev/mmcblk0
BEFORE will list existing partitions.
