How to mount an additional Elastic Block Store Linux


I needed to add an elastic block store to a Ubuntu Linux Server. I created the instance from with the AWS admin console. What was missing was how to have the Ubuntu instance recognize it. Turns out it is fairly simple. Format, and mount.

Mount

SSH into the instance and become root.

\$ ssh [email protected]  
\$ sudo su  

Find the new volume's name

\$ fdisk -l

Disk /dev/xvda1: 8589 MB, 8589934592 bytes  
255 heads, 63 sectors/track, 1044 cylinders, total 16777216 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: 0x00000000

Disk /dev/xvda1 doesn't contain a valid partition table

Disk /dev/xvdf: 107.4 GB, 107374182400 bytes  
255 heads, 63 sectors/track, 13054 cylinders, total 209715200 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: 0x00000000

Disk /dev/xvdf doesn't contain a valid partition table

In my case it's "/dev/xvdf"

We'll need to format the volume.

\$ mkfs -t ext3 /dev/xvdf

Now to mount it

\$ mkdir /mnt/ebs-volume-1  
\$ mount /dev/xvdf /mnt/ebs-volume-1/
