Re: growing XFS with GPT partitions

This is apparently a rather common problem, as I keep receiving messages 
about this every few weeks. Here's the latest:

I solved the problem for writing my own program for reading and writing 
GPT labels. With that it was pretty straight-forward to repartition, 
even though one had to edit the source code to do any changes.

Run the program to see the current GPT info, then add lines to set new 
values at the line marked // TODO: operations here. Run the program and 
it will display the old data, then it'll do the changes and perform some 
consistency checks to verify them and print the new data. It will then 
ask for confirmation before writing anything to disk.

Before writing this program I tried inspecting parted source code to see 
if it could be fooled into resizing the partition without touching the 
XFS or if it could use external xfsgrow tool, but unfortunately the 
source code was too abstract and I had to give up.

Hopefully someone adds this feature, as there clearly is need for it...
