In fact, the Grizzly release introduced the multi-backend feature. This feature allows to have more than one backend on a same compute (ie, to be able to have several cinder-volume running on a same compute). This feature is not available in Folsom: you can only run one cinder-volume per compute (in that case, if you want to manage several backends, you have to have several computes).</div>

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

Hi,<br>
<br>
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 ?<br>
<br>
As per the doc [1], I would say the answer is no,
but could you please confirm ?<br>
<br>
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).<br>
<br>
Thanks,<br>

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 ?<br>
