I have a 1TB (or thereabouts) SSD drive on my laptop, on which is installed Ubuntu 14.04.
I want to increase the size of the boot partition, so I've booted from a live CD, and ran GParted.
I have two partitions - the main one,
/dev/sda2, and the boot one,
/dev/sda2 is an encrypted partition called
/dev/sda5. It looks like this:
I can right click on
/dev/sda2, and choose "Resize/Move", but on the following dialog it doesn't let me make any changes.
Is this because I would need to shrink the encrypted partition within
/dev/sda2 first, and you can't resize encrypted partitions? That seems plausible but my knowledge runs out at this point.
