Public bug reported:
We can replicate the corruption pretty much at will. The sequence of
events to trigger it is:
Create an instance using a cloud image
Start a job running with the following command: "dd if=/dev/urandom
of=/var/tmp/mjb.1 bs=4M count=1000"
Live migrate the instance using a command like: "nova live-migration
--block-migrate <server-id> <target-hypervisor>"
Once the migration has finished, stop the dd job on the instance
do a "Hard reboot" of the instance
When the instance boots, file system corruption will be observed and it won't
boot correctly
