We have a MySQL database on EC2 and are looking at the disk IO performance there. Currently we have a single EBS volume with XFS and take snapshots for backup. It seems that a lot of people have seen significant performance gains by striping across multiple EBS volumes with software RAID. If this is done, how does one take snapshots and ensure the consistency of the file system? It seems to me that restoring the file system from multiple snapshots could be tricky.
