Amazon EC2 and EBS mount point tip

After a few experimentation on Amazon EC2 and its new feature(Amazon EBS), I was able to share some tips for an EBS device formatted as XFS. Always make sure that the file permission belongs to the correct user(s) UID when you start using the mounted EBS device(unless of course if its a newly created/formatted).

Thanks to Eric Hammond for posting my name on his MySQL Amazon EBS tutorial. http://ec2ebs-mysql.notlong.com

Amazon EBS (Elastic Block Store)

Cool…Here is the latest on the AWS services. The Elastic Block Store.

“You can snapshot a volume to Amazon S3 with ease, and then, if needed, create new volumes (of the same or different sizes) using the snapshot as a base. Of course, if you create a new volume with a size that doesn’t match the size of the volume where you took snapshot, you will have to resize the new file system. When you create a new volume based on an S3 snapshot, the data is loaded lazily; there’s no need to wait for the snapshot to load.”

To check out this feature easily, I use ElasticFox addon. I need to upgrade it first at http://s3.amazonaws.com/ec2-downloads/elasticfox.xpi

It’s seems a little bit easier to implement some db and ec2 backups using this feature.
Kudos to Amazon guys.
