Hi,
I have installed an ISO image 667 version which is stable and created template,now I started with few commnads and was able to run docker ,now I had a sh file with
docker run calling the images repository and run ,I got space issue when trying to download few of the images from docker ,
Now I added a data disk using fdisk /dev/sda command and was able to create partition but when I try mount it onto /var directory and run it it fails to recognize docker
I am getting error can you please help me resolve the mounting issue all I need is to be able to expand the memory to download the images
Thanks
Sree

Usage:
fdisk [options] <disk> change partition table
fdisk [options] -l [<disk>] list partition table(s)
Display or manipulate a disk partition table.
Options:
-b, --sector-size <size> physical and logical sector size
-c, --compatibility[=<mode>] mode is 'dos' or 'nondos' (default)
-L, --color[=<when>] colorize output (auto, always or never)
colors disabled by default
-l, --list display partitions end exit
-o, --output <list> output columns
-t, --type <type> recognize specified partition table type only
-u, --units[=<unit>] display units: 'cylinders' or 'sectors' (default)
-s, --getsz display device size in 512-byte sectors [DEPRECAT ED]
--bytes print SIZE in bytes rather than in human readable format
-C, --cylinders <number> specify the number of cylinders
-H, --heads <number> specify the number of heads
-S, --sectors <number> specify the number of sectors per track
-h, --help display this help and exit

CoreOS auto-resizes on boot if it detects that that hdd has increased.
For example, for KVM/Libvirt virtualization you simply do "qemu-img resize coreos.qcow +10GB" and on boot CoreOS will automagically expand
