Public bug reported:

Due to the fact that rebuild detaches block devices when instance is
still powered on, data written to attached volumes can possibly be lost,
if it hasn't been fsynced yet.

We can prevent this by allowing instance to shut down gracefully before
detaching block devices during rebuild.
