Creating Amazon EBS volumes using existing snapshot is creating problems

Hi All,

I created a EBS volume, attached and mounted it on a EC2 instance. Created few sample text files in the mounted directory and took a snapshot from AWS console.

Problem is when I create a new EBS volume using this snapshot and mount this new volume, I am not seeing the stored content (in snapshot).

What can be the issue? Is my data not going in snapshot? Or newly created volume having any issue?

Thanks in adavnce, Sunil

This should normally work. The only explication could be a mistake during the execution of the commands, e.g. that you created a file-system on the newly created volume instead simply mounting it (happened once to me).

I order to mount EBS, attached with a instance, followed following steps:yes | mkfs -t ext3 /dev/sdfmkdir /mnt/ebs-storemount /dev/sdf /mnt/esb-storeAnd then created text files in "/mnt/esb-store" and created a snapshot using AWS Console.I think if I mount original EBS and snapshot EBS on same EC2 instance, it's not different from mounting both EBS on different EC2 instances.

Found the issue. Not a system admin, else I should have know this thing. Following command is flushing the data from the EBS volume.

yes | mkfs -t ext3 /dev/sdf

On an EBS volume, started using snapshot, don't run above command. Hope it this thread will help someone in future.
