Subject Re: register two local LVM storage in cloudstack
Date Thu, 29 Nov 2012 10:40:14 GMT

I think yes, PreSetup is shared storage. If you use local storage you will
only get vms running in one node (you won't be able to migrate instances to
other hosts). You may need to create a service offering that uses shared
storage and the desired storage tag.
