Attaching disk and swap to EC2 instance

Adding a disk to EC2 instance:

1) Note the availability zone of the EC2 instance.
2) Create a new EBS volume in the same zone.
3) After the volume is created, attach the volume to the EC2 instance.
4) SSH to the EC2 instance and run 'dmsg' command to see if the disk is available.
5) It displays "unknown partition table" at the end of the output log then the volume is attached to the instance.
6) We now have to create partition and use it.
	sudo fdisk /dev/xvdf
	(you enter fdisk mode)
	p (prints the current partition table)
	n (create new partition) then
	P (Primary partition)
	w (write the channges)
7) create filesystem on the disk
	sudo mkfs -t ext4 /dev/xvdf1
8) mount the file system
	sudo mount /dev/xvdf1 /data
9) mount the volume at boottime
	sudo vi /etc/fstab
   At the end add
	/dev/xvdf1	/data	ext4	defaults	0	0
10) Reboot and verify
	sudo reboot


Adding swap space:

1) Note the availability zone of the EC2 instance.
2) Create a new EBS volume in the same zone.
3) After the volume is created, attach the volume to the EC2 instance.
4) SSH to the EC2 instance and run 'dmsg' command to see if the disk is available.
5) It displays "unknown partition table" at the end of the output log then the volume is attached to the instance.
6) We now have to create partition and use it.
	sudo fdisk /dev/xvdf
	(you enter fdisk mode)
	p (prints the current partition table)
	n (create new partition) then
	P (Primary partition)
	w (write the channges)
7) Now create swap space using
	sudo mkswap /dev/xvdf1
8) Now activate the swap space using
	sudo swapon /dev/xvdf1
9) Verify using
	free
10) mount the swap at boottime
	sudo vi /etc/fstab
   At the end add
	/dev/xvdf1	swap	swap	defaults	0	0
11) Reboot and verify
