Mounting an attached ebs volume in EC2

Solution 1:

Here's a complete set of commands that you should run once you've attached the EBS volume to your EC2 instance:

mkfs -t ext3 /dev/sdf   # (NOTE - if you created your EBS volume from a snapshot of another volume and want to preserve its data, skip this step)
echo "/dev/sdf  /testName  ext3     noatime  0 0" >> /etc/fstab
mkdir /testName
mount /testName
df -h                   # (you should now see a new /testName file system mounted on the EBS volume)

Solution 2:

I had the same problem while mounting an EBS volume that I had taken a snapshot of. The gotcha was that when I attached the volume (e.g., /dev/sdf), it was actually partitioned so (/dev/sdf1) was also created. I was able to mount /dev/sdf1 with no problem.

Solution 3:

Have you created the filesystem yet?

mkfs -t ext3 /dev/sdf
