I was looking at using the mysqllvm ami for the mysql servers. I'm
assuming the lvm has the following two benefits: freezing the disk so
Amazon can make EBS->S3 snapshots, and so we can grow a database
volume over time (since they charge based on the *allocation* space of
the 'drive').

ZFS also can freeze a volumen, and add drives (and raid them). But it
also can do compression which reduces the space used and boosts the
effective transfer rate.* Since ZFS-FUSE is a user mode FS for
Linux**, it should work with EBS on EC2.

A feature idea for scalr is to automate the enlargement of the EBS
backed volume for the MySQL machines -- start with a base one that the
user creates, and then add new ones (based on a user 'ebs-add-chuck-
size' param) before the disk gets full -- elastic drive space.
