Re: [ceph-users] Virtual traffic on cluster network
Hi, Ceph cluster network is only useful for OSDs. Your vm only need access to public network (or client network if you prefer). My cluster is also in a virtual environnement. MONs and MDS are virtuals. OSDs are physicals of course. -- Thomas Lemarchand Cloud Solutions SAS - Responsable des systèmes d'information On jeu., 2014-12-04 at 12:45 +, Peter wrote: Hi, i am wondering about running virtual environment traffic (VM - Ceph) traffic on the ceph cluster network by plugging virtual hosts into this network.

Re: [ceph-users] Virtual traffic on cluster network
I was thinking the same thing for the following implementation: I would like to have an RBD volume mounted and accessible at the same time by different VMs (using OCFS2). Therefore I was also thinking that I had to put VMs on the internal CEPH network by adding a second NIC and plugging that into this network. Is this a bad idea?? Do you have something else to propose?? Regards, George On Thu, 04 Dec 2014 14:31:01 +0100, Thomas Lemarchand wrote: Hi, Ceph cluster network is only useful for OSDs.

Re: [ceph-users] Virtual traffic on cluster network
perhaps I'm confused about it, but what I mean is, virtual host to storage traffic, ie: physical virtual host machines plugged into ceph cluster network. - P On 04/12/14 13:54, Georgios Dimitrakakis wrote: I was thinking the same thing for the following implementation: I would like to have an RBD volume mounted and accessible at the same time by different VMs (using OCFS2).
