Hi Cheung,

Can't figure out much from your logs. Its more likely to be an LVM thing.
We haven't tested this scenario, as the tests we run only tests 1GB volumes
for performace reasons. But why would someone create a volume bigger than
that? :P

Can you open a bug on launchpad? Describing the steps to reproduce.
