We have added an extra data disk to the OS disk following this tutorial http://azure.microsoft.com/en-us/documentation/articles/virtual-machines-linux-how-to-attach-disk/
Essentially we are trying to increase the OS disk
However cant seem to mount the disk and have access to it
_ Apparantly - *The OS disk size may be significantly smaller for Linux virtual machines created from images available in the Image Gallery.
How can this be altered or increased
