Re: [Cinder] Re: Multiple machines hosting cinder-volumes with Folsom ?


Thanks but it didn't match my needs. I already know how to deploy Cinder on a single host, my point was more relative to deploying a second Cinder-volume instance, and if yes, what to do.

Nevermind, I successed in deploying a second Cinder-volume, just by looking at the packages and the confs. It's pretty straightforward, so I'm not surprised it wasn't documented. Nevertheless, I think that the Grizzly doc I mentioned [1] is confusing : by looking at it, I was thinking Cinder was unable to have two distinct volumes with Folsom release. Maybe updating the folsom branch for Cinder documentation, precising it *is* possible, is worth a try ?

Anyway, I'm documenting out the process in my own (new) blog. Keep tuned, I'll post the URL out there.

Hi Sylvain,

Maybe the folsom documentation for cinder will help you:

            It sounds quite unclear for me about the possibility *in
            Folsom* to have two distinct Cinder hosts having each one
            LVM backend called cinder-volumes ?

            As per the doc [1], I would say the answer is no, but
            could you please confirm ?

            If so, do you have any idea on how to trick a nearly full
            LVM cinder-volumes VG ? (I can't hardly add a new disk for
            adding a second PV).


            [1] :

        Replying to myself. As per [2], it seems having a multiple
        cinder-volume setup in Folsom is achiveable. Could someone
        from Cinder confirm that this setup is OK ?
