I recently read a thread on how to properly migrate my system from my 8GB sandisk to a 16GB one. The reason is I needed to apt dist-upgrade but there wasn't enough capacity. Also, my 8GB one is old so it's pretty beat up already.
I lost the link of the thread and I can't seem to find it now, but to summarize, to do a proper transfer it's best to image (via dd) my whole 8GB first, verify the integrity, then dd it again to my 16GB. after it's done, I have to increase the capacity of my root partition using parted.
My problem is the 3rd partition in my 16GB flashdrive doesn't seem to have increased.
here's a df -H

as you can see, /dev/sdb3 should have well over 11G. However, once it's mounted it seems to loose a lot of capacity it should have.
P.S. I don't know where to insert this, but I'm using a luks encryption on that sdb3 partition, and I think that's messing with it.
How can I fix this? If it has something to do with luks, will it be possible to fix it without losing data?
I don't have any way to backup my data, and I'm always on metered connection so uploading my data online is a no way to go.
