Well, it's a bit of a problem to fix this in setup-storage: The experimental
version nowadays creates partitions that end in sector boundaries, but previous
versions incl. mainline make partitions end in cylinder boundaries (on msdos
disk labels). As sizes are rounded downwards, those 512MiB ended up being only
534610944B; using the new sector-alignment it would be 536870912B, which doesn't
fit in the smaller free space.

If that system is just a test server, it's probably best to drop the preserve*
stuff for a moment and update sizes. If not, try 509 instead of 512, that should
be fine.

Thanks a lot,
Michael
