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


[DEFAULT]
rootwrap_config = /etc/cinder/rootwrap.conf
sql_connection = mysql://cinder:password@localhost/cinder
api_paste_confg = /etc/cinder/api-paste.ini
#iscsi_helper=iscsiadm
#iscsi_helper = ietadm
iscsi_helper = tgtadm
volume_name_template = volume-%s
#volume_group = cinder-volumes
verbose = True
auth_strategy = keystone
iscsi_ip_address = 192.168.3.1
scheduler_driver=cinder.scheduler.filter_scheduler.FilterScheduler

# Rabbit authorization
rabbit_host = localhost
rabbit_port = 5672
rabbit_hosts = $rabbit_host:$rabbit_port
rabbit_use_ssl = false
rabbit_userid = guest
rabbit_password = password
#rabbit_virtual_host = /nova

state_path = /var/lib/cinder
lock_path = /var/lock/cinder
volumes_dir = /var/lib/cinder/volumes
#rpc_backend = cinder.rpc.impl_kombu

enabled_backends=orion-1,orion-4
[orion-1]
volume_group=cinder-volumes
volume_driver=cinder.volume.drivers.lvm.LVMISCSIDriver
volume_backend_name=LVM_iSCSI
[orion-4]
volume_group=cinder-volumes-2
volume_driver=cinder.volume.drivers.lvm.LVMISCSIDriver
volume_backend_name=LVM_iSCSI

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

Any ideas?

Thanks :)
