Open Stack

Hi all, I'm re-installing OpenStack using Devstack and I'm building a
multinode environment. Starting from the installation of the Controller
node, it fails and says:

> cinder type-create lvmdriver-1> 2015-04-21 15:02:49.370 | ERROR: Unable to establish connection to> http://10.30.3.117:8776/v1/e06dceea27b6469bb0cf5c2f075da581/types> 2015-04-21 15:02:50.067 | ++ err_trap> 2015-04-21 15:02:50.069 | ++ local r=1> 2015-04-21 15:02:50.166 | Error on> exit

Two days ago I have already installed it, but yesterday morning I had some
problem and decided to *unstack* and *stack* again everything. I have
*unstacked* in all compute hosts and also in the controller, than I've done
*./clean.sh* and removed the folder /opt/stack. But now I can't install it
anymore. Could someone help me please?

Moreover when I unstack I have:

Volume group "stack-volumes-lvmdriver-1" not found Skipping volume group
stack-volumes-lvmdriver-1

And when I did ./clean.sh I have this error:

/home/stack/devstack/lib/cinder_backends/lvm: line 41:
clean_lvm_volume_group: command not found

Thanks for your help.
