Re: 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.

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??

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.

Hi,

i am wondering about running virtual environment traffic (VM -> Ceph)
traffic on the ceph cluster network by plugging virtual hosts into this
network. Is this a good idea?
My thoughts are no, as VM -> ceph traffic would be client traffic from
ceph perspective.
Just want the community's thoughts on this.

thanks
