I'm experimenting with creating a software RAID 0 device from 4 EBS volumes on Ubuntu 9.10 running at Amazon AWS following this guide:
http://alestic.com/2009/06/ec2-ebs-raid
The device appears (and according to SysBench is 3.5x faster than a regular attached EBS volume).
Problem is, when I reboot the instance, all files on the RAID device are gone. The device is available and mounted where expected, but contains no files. I am able to write new files to it, which survive until the next reboot.
