I think it is always better to give control to the administrator on whether to enable/disable local storage in a cluster/zone level. If local storage pool is available by default then it may be difficult to manage all of them in case of a cluster with large number of hosts. Also in some cases it may be required not to allow local volume creation on a selected set of hosts (say in a particular cluster).

Local storage as a storage pool resource, by default, is always available on each hypervisor host. CloudStack mgt server should not hide the existing available resource. To use local storage or not, that all depends on disk/service offering. > > -Koushik > > -----Original Message----- > From: Prasanna Santhanam [mailto:prasanna.santha...@citrix.com] > Sent: Monday, July 30, 2012 4:13 PM > To: cloudstack-dev@incubator.apache.org > Subject: Re: Local storage support for data volumes > > On Mon, Jul 30, 2012 at 06:23:44AM -0400, Koushik Das wrote: > > Currently in CS only root volume can be created on local storage. > > This feature is to support creation of data volumes on local storage. > > Please refer to [1] for the details.
