I'm glad some people are having success with resizing the partitions on the RaspberryPi itself.
For me it just won't work.
Here's what I did : (maybe someone else has had success with resizing the partition in Archilinux and can help out)
I followed instructions here http://elinux.org/RPi_Easy_SD_Card_Setu ... spberry_Pi
The are only 2 partitions on archlinux img - so I just adapted the instructions and deleted then recreated partition 2.
The recreated partition started at same block as the the partition I had just removed.
I used the default for the end block. This seemed to create the partition using all available space on the sd card - about 14.9 GB
All seemed to go well.
I did see an error message when writing the partition, it said something about the partition will not be usable by kernel until reboot or reloading some kernel modules.
I thought it was fair enough - and that the instructions had said that the partition will not be useful until rebooting anyway - so I rebooted.
After reboot I was unable to log in.
I was presented with a login: prompt but after typing root - the prompt would just immediately popup again.
Eventually giving me this error message
"Unable to determine your tty name"
I'm going to fire up my old ubuntu laptop and try parted, although I would really like to be able to get htis working for Archlinux on the RaspberryPi - since in theory having to have other operating systems around - seems to defeat the point.
Also - perhaps there is another approach where the .img file could be manipulated to take up 8GB or 16GB ?
Does anyone know if this is doable ?
I'm on OS X (which is the basket case of *nix distros) so if anyone knows how to resize it using some OS X tools then do tell.
