-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi guys.
at the moment Cinder doesn't allow to attach a volume twice. I mean i need to build for each application cluster an extra storage share point (NFS, glusterFS, ...) in the tenant. Other way is to build a shared storage for all tenants. Both options are more expensive than needed because: * Cinder backend servers are highly redundant (maybe 3 times mirror) => data will be stored 3 times * Creating 2 VM's for shared storage in a tenant with NFS + drbd => data will be stored 6 times 2xNFS x 3xCinder Better way would be to attach a volume directly on n instances. The administrator must be solve write conflicts with known possibilities. I've found two blueprints to this topic: https://blueprints.launchpad.net/cinder/+spec/shared-volume https://blueprints.launchpad.net/cinder/+spec/multi-attach-volume Do anyone know if this will be include in Juno ? I didn't find any on launchpad for the milestones. Thanks and Cheers Heiko - -- anynines.com -----BEGIN PGP SIGNATURE----- Version: GnuPG v1 iQEcBAEBAgAGBQJUPm6GAAoJELxFogM4ixOFVA0IAJnmk2XN/p4fGpS4aWHmA0Tu h8zVDbJKa7jL8Gmn/lTnefGDEMFA3La8Vj18eFW/4t6gPN6Y6J2t7mESmkho5hcp Z7ld/K+qj3Ii+Mh2jWbQijNIWKNy8J2+H8axidyjVeGamftv/HlDE43jtsLl3/p6 qj0M5MqiiOifnh4UEBT7dIvrWbAdOpyRDQnqNnGiaGgZaLHdX5gtnVns6MtvrkJT HmBEowHxZm3D/8bUTr/zW6IJwe1BlASNPUaeAK2k3uZ6jr6OR9xjMj2an7bJAtoD vA0vv5WpO5nCfSaAQlfRycCsygrPnN4v2eKDJ9NZXcKLUY2bx4jhVWSNmx/u+Eg= =Wagz -----END PGP SIGNATURE----- _______________________________________________ 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
