In current openstack live migration feature, a flag --instances_path specifies the path which has to be on shared storage. Live re-balancing sounds like good idea, and I think at least, just "--instances_path is on the glusterFS" is good option to users. If you want any help, my colleague and me would love to do ^^; > -----Original Message----- > From: [email protected] > [mailto:[email protected] > t] On Behalf Of Soren Hansen > Sent: Monday, June 06, 2011 7:40 AM > To: Shehjar Tikoo > Cc: [email protected] > Subject: Re: [Openstack] Integrating GlusterFS with OpenStack > > 2011/6/3 Shehjar Tikoo <[email protected]>: > > We're aiming to integrate Gluster with Openstack in a way that allows > > GlusterFS to be used as the storage for application volumes as well > as VMs. > > I am interested in hearing your ideas on how such an integration can > > be performed.
