Amazon EBS doesn't allow disks to be resized -- this is something I asked for
a long time ago, but I'm guessing it isn't something a very large number of
people are demanding.  Of course, with EBS you can always create a new volume,
sync everything across, then destroy the old volume[*]; so it's not as large
a problem as on a local Xen deployment where the amount of disk space you have
available might limit your ability to temporarily duplicate everything.

[*] In theory, at least.  Last time I tried I got a FreeBSD kernel panic when
I detached an EBS volume from a running instance.
