Your suggestion is exactly the process I attempted to follow, but it was not permitted,which is why I have come to the forum. I defined a storage service offering, local, of1G. When I try to create a data disk using that offering, the attempt fails with the message 'Zone is not configured to use local storage but volume's disk offering LocalSwap uses it'.I understand that the 'local storage' enabling configuration is in the zone definition, and isalterable at any time. I see the box in the UI to enable it. This leaves me a dilemma... if I configure the zone to use local storage, then I am uncertainof the degree of risk to which I expose the zone... does my next VM ROOT disk end up onlocal? Or is that taken because the VM disk offering will use 'shared' and this is how the placementis controlled - via shared/local? I want to be sure before I do this, as I have a number ofguests and data disks already defined and do not dare risk blowing up this running cloud. Thanks for the response!
