<div class="moz-cite-prefix">Thanks Jerome for the clarification.<br>
I just posted out a blogpost for adding a Second volume to Cinder
in Folsom [3]. Maybe it could be merged with the official Folsom
Ubuntu Cinder documentation ? There is only H/A aspects that are
mentioned by now.<br>
<br>
Someone from the documentation team ? Could you please point me
out some materials for committing a new doc for that ?<br>
<br>
Thanks,<br>

<div style="">Great to know that you found how to solve your

<div style="">Thanks for reporting that you found the Grizzly
doc confusing.</div>
<div style="">
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>

<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>
