Hi Eduard,
According to the error you had, I assume your volume format is sparse
(probably qcow2).  When you create a volume out of it, Cinder will convert
the format to 'raw', which increases its size.  I believe the 'size'
parameter is now optional if you create a volume from a source (such as
image, snapshot, or other volume).

With regard to your question on how to view this on the client side, if the
volume goes to 'error' state, there is no way to know why right now without
checking logs.  Yes, this is bad.
