I'm running Ubuntu from USB media, which has a drive capacity of 250 GB, all existing as one FAT32 partition.
However, when I created the bootable Ubuntu drive, only 4.79 GB were allocated for usage.
Rather than put files directly into the /cdrom where the drive is mounted, I want to expand what is listed here in aufs to be at least 200 GB. I'm hopeful that I can do this live.
Output of df :

Output of fdisk -l :

So basically what I want to do is get /dev/sdb1 to be entirely, or almost entirely read as aufs.
I'm confused over how to do this, as the file systems are all part of /dev/sdb1 on one big partition, rather than separate partitions for separate file systems.
