Growing Amazon EBS Volume sizes

I followed all the answer, all have something missing with all respect.

If you follow these steps you can grow your EBS volume and keep your data (this is not for the root volume). For simplicity I am suggesting to use AWS consule to create snapshot,... you can do that using AWS command line tools too.

We are not touching the root volume here.

Goto your AWS console:

1. Shutdown your instance ( it will be for a few minutes only)
2. Detach the volume you are planning to grow (say /dev/xvdf)
3. Create a snapshot of the volume.
4. Make a new volume with a larger size using the snapshot you just created
5. Attach the new volume to your instance
6. Start your instance

SSH to your instance:

 $ sudo fdisk -l

This gives your something like:

Disk /dev/xvdf: 21.5 GB, 21474836480 bytes
12 heads, 7 sectors/track, 499321 cylinders, total 41943040 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0xd3a8abe4

    Device Boot      Start         End      Blocks   Id  System
/dev/xvdf1            2048    41943039    20970496   83  Linux

Write down Start and Id values. (in this case 2048 and 83)

Using fdisk ,delete the partition xvdf1 and create a new one that starts exactly from the same block (2048). We will give it the same Id (83):

$ sudo fdisk /dev/xvdf 

Command (m for help): d
