I don't believe that is the plan here, generally speaking. The Gluster snapshot support (for attached volumes) involved API work for Cinder and Nova but none of the code uses functionality which is specific to GlusterFS. It is currently only used by the Gluster Cinder driver but the plan going forward, in my view, is to adopt the same functionality for the Cinder NFS driver (which has same architecture as Gluster from Cinder's current point-of-view) and also enable other drivers working with the same mounted-remote-file-system model to gain snapshot support. The snapshot functionality is currently GlusterFS-only because I had to implement it somewhere first, and only had so much time during Havana. :) As an example: a driver was submitted for XtreemFS during Havana and rejected on the basis of not supporting snapshot functionality. The work done for GlusterFS in Havana enables that driver to reuse most of the same infrastructure for snapshots and therefore have a path for acceptance going forward, should the author continue pursuing integration. > > > _______________________________________________ > Mailing list: http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack > Post to : openstack@lists.openstack.org > Unsubscribe : http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack > _______________________________________________ Mailing list: http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack Post to : openstack@lists.openstack.org Unsubscribe : http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack
