that means the volume is still in use. (lvopen : 1) make sure it's not by<br>
checking the process, qemu-nbd, etc...<br>

Oh yah true!<br>
not sure “conductors” exist yet for Cinder, meaning meanwhile, every node<br>
needs a direct access to the database<br>
glad to hear it’s working :)<br>

Hello Razique, I got a couple of doubts, do you know if I need to do<br>
something else that's is not on the link you sent me? I'm asking because I<br>
followed the configuration but it's not working, here is what I get: I've<br>
installed the cinder-volume at the second computer that have the HD, and<br>
I've changed it's cinder.conf. I've changed too the master's cinder.conf<br>
like is following:<br>

The cinder.conf on the second computer is like this but the IPs are<br>
changed with the controller IP (It has the cinder-api), and when I run<br>
service cinder-volume restart at the second computer it's status is<br>
stop/waiting.<br>
<br>
Any ideas?<br>

If I’m not mistaken, you only need to install the “cinder-volume’<br>
service that will update its status to your main node<br>
:)<br>

Ok in that case, with Grizzly you can use the “multi-backends”<br>
feature:<br>

what is your actual Cinder backend? Is it a hard disk, a SAN, a<br>

Hello guys, I have a Grizzly deployment running fine with 5<br>
<br>
nodes, and I want to add more storage on it. My question is, can I install<br>
a new HD on another computer thats not the controller and link this HD with<br>
my cinder that it can be a storage too?<br>
<br>
The computer I will install my new HD is at the same network as<br>
<br>
my cloud is. I'm asking because I haven't seen a question like that here.<br>
Does anybody knows how to do that? Have a clue? Any help is welcome.<br>

Thank you all.<br>
