Why cant it use /dev/xvda4 when /dev/xvda2 is full ? /dev/xvda4 is newly mounted. Running ubuntu 12.04LTS.

That isn't how Linux works.
You need to move files from
to some other place.
You can find which files are using space by using du.
Will list files and directories ordered by which use the most space.
You could move them and symlink them if needed so that they appear to be in the previous location.
e.g. I use uvt on my system and so my uvt directory is rather large, I may want to move it out of my root file system
In this case I'd have to shutdown those uvt machines before I move them. Depending on what you move you may need to shutdown services and/or restart them after the data is moved.
