Thanks Yafeng Yafeng, Would you describe your use case for cinder multi-attach with ceph backend? I'd like to understand better whether manila (file share infrastructure as a service) with CephFS native or CephFS-NFS backends would (as Erik McCormick also suggested) meet your needs. -- Tom Barron __ OpenStack Development Mailing List (not for usage questions) Unsubscribe: openstack-dev-requ...@lists.openstack.org?subject:unsubscribe http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
Re: [openstack-dev] Ceph multiattach support
The lack of ceph support is a ceph problem rather than a Cinder problem. There are issues with replication and multi-attached RBD volumes asd I understand it. The ceph folks are aware but have other priorities presently. I encourage making your interest known to them. In the meantime, check out Manilla with cephfs if you are running modern versions of both Ceph and Openstack. -Erik On Wed, May 30, 2018, 10:02 PM fengyd wrote: > Hi, > > I'm using Ceph for cinder backend. > Do you have any plan to support multiattach for Ceph backend? > > Thanks > > Yafeng > __ > OpenStack Development Mailing List (not for usage questions) > Unsubscribe: openstack-dev-requ...@lists.openstack.org?subject:unsubscribe > http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev > __ OpenStack Development Mailing List (not for usage questions) Unsubscribe: openstack-dev-requ...@lists.openstack.org?subject:unsubscribe http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev

A lot of people have expressed an interest in this, so I'm sure multi-attach with Ceph will eventually be supported. However, it will require a fair amount of investigation to fully understand what is needed for the feature to work correctly. The situation is summarized in a comment in the Cinder code [1].
