Marios Andreou commented on DTACLOUD-221:
-----------------------------------------

ACK - applies cleanly to master. Dies since you 'own' the fgcp driver and this patch only touches fgcp_driver.rb, I'm happy to push this to master.  Commit hash:

300e0534ed702d86b8ae73897fa8160bc536ffc2

Just out of curiosity/general knowledge - is it easy to explain what 'system' vs 'storage' volumes are in the context of fgcp (I can gather from their names that storage is external 'attached' storage, whereas 'system' - holds the OS/root storage for the instance, but which may be ephemeral and not persist once the instance is powered down [this last bit depends on whether fgcp instances are stateless or stateful - i think they are stateful like rhevm so you can start/stop them right - in which case system storage is not ephemeral?]).
