I ran into a small issue trying to mount an EBS drive today, I figured it was worth documenting. After attaching an EBS drive I created to my instance, I tried to mount the drive:

db1:~$ sudo mount /ebs/

And got the following error (which I have never seen before):

db1:~$ sudo mount /ebs/
mount: wrong fs type, bad option, bad superblock on /dev/xvdb,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so

I looked around multiple sites and ended up with the following solution:

db1:~$ sudo mkfs.ext3 /dev/xvdb

After running mkfs (make filesystem), I could successfully mount my volume.
