You could try making the file smaller like 5G say:

dd if=/dev/zero of=/opt/EC2AMIIMAGE/ami-rhel6.1-32bit-base bs=1M count=5120

Or you could build your AMI from a machine with more disk space if you need more disk.

Thanks for the practical help on creating EC2 AMIs. I have been following your article, but for an m1.small Redhat 32-bit instance. When I get to the creation of the 10GB file to hold the OS files I get a message saying I’ve run out of space:

[root@server]$ dd if=/dev/zero of=/opt/EC2AMIIMAGE/ami-rhel6.1-32bit-base bs=1M count=10240
dd: writing `/opt/EC2AMIIMAGE/ami-rhel6.1-32bit-base’: No space left on device
4225+0 records in
4224+0 records out
4429357056 bytes (4.4 GB) copied, 233.488 s, 19.0 MB/s

When I check the amount of available disk with “df -h” I get

[root@server]$ df -h
Filesystem Size Used Avail Use% Mounted on
/dev/xvde1 5.7G 5.7G 0 100% /
none 837M 0 837M 0% /dev/shm

Do you know how to fix this problem.

Thanks

Thanks a lot for this great document. I was successfully create EC2 image and placed on s3. Can I discuss some other issue related to EC2 image bundling. Recently we got an instance –> created snapshot –> Now it seems to be placed in EBS. I am looking to bundle this instance on S3 bucket but when I try to do so, it throws “ERROR: Can’t access instance metadata. If you are not bundling on an EC2 instance use –no-inherit.” error . I tried to follow Amazon Ec2 forum and couldn’t get anything. Could you please suggest?

Thanks,
Shah

Thanks for the great site.I have a query regarding installing gcc in the image i am creating.I had followed your steps and had registered an image in EC2.When i tried to install php from there,the gcc was missing.please let me know how to install gcc.

Note: I am installing the OS my mounting it in any linux directory and pointing my YUM conf to that directory.

The manifest file is the way all the individual files come together. You should see that file at the end of the different segmented files.

Yogesh,

Your welcome

So now i uploaded the files to S3, but i can only see it as filename.00 filename.01. till filename.51, how to combine them as .img file now?

i did it partially through ec2- tool from console, and through upload link at aws manage link.

Glad you found the article helpful.

http://alestic.com/2008/05/kernel-modules-2-6-21 is a good article on kernel modules.

http://www.amazon.com/Host-Your-Web-Site-Cloud/dp/0980576830 is a good book that recently came out to start with. Other then that just check out all the blogs and give it a whirl.

First thank you for the post. It is by far the best and most practical and informative guide I’ve seen around.

I’ve searched around in the aws docs, but can’t find informative or practical links / downloads about the EC2 kernel modules. Where did you get the ones you used for this article?

Thanks!
