====== Installation and Configuration of OpenStack Cinder Volume ======

Author: 
   * Alvise Dorigo (INFN Padova)
===== Prerequisites =====

One node with:
   * Updated SL6/CentOS6 (6.4 or 6.5) 
   * Make sure that yum autoupdate is disabled
<code bash>
root@controller-01 ~]# grep ENA /etc/sysconfig/yum-autoupdate
# ENABLED
ENABLED="false"
</code> 
   * At least 20GB HD for operating system and OpenStack software and related log files
   * SELinux configured as "Disabled" (''/etc/selinux/config'')
   * EPEL 6-8
   * A MySQL (possibly a HA cluster) endpoint the Cinder volume daemon can connect to (in this guide we're using our MySQL Percona cluster's IP ''192.168.60.10'')
   * A HAProxy/Keepalived cluster to use for load-balancing and Virtual IP (in this tutorial we're using the IP ''192.168.60.40'' for mgmt net and ''90.147.77.40'' for public net)
   * A GlusterFS shared filesystem mounted on ''/cinder'' (must install gluster-fuse RPM before: ''yum -y install glusterfs-fuse''). Let's assume, for the rest of the this guide, that the exporting endpoint is **''cld-nl-04.data.pd.infn.it:/cinder_volume''**

Note 1: that the specified endpoint must belong to the data network in order to make the cinder-generated traffic pass through the data network. In this case we have two addresses
   * **cld-nl-04.data.pd.infn.it** (corresponding to IP **192.168.61.59** on data network)
   * **cld-nl-04.cloud.pd.infn.it** (corresponding to IP **192.168.60.59** on management network)

the first one must be used as export endpoint. 

Note 2: also make sure that on the gluster server side the userid e groupid have been correctly set:
<code bash>
# gluster volume set volume-cinder-alvise owner-uid 165
volume set: success
# gluster volume set volume-cinder-alvise owner-gid 165
volume set: success
</code>

where 165 is the UID and GID of the cinder user running the ''cinder-volume'' process.
===== Cinder Volume =====
The host's IP address where Cinder Volume will be installed into is ''192.168.60.42''. In addition consider the two controller IPs where clustered RabbitMQ is running: ''192.168.60.41'' and ''192.168.60.44'' (see Controller installation [[http://wiki.infn.it/progetti/cloud-areapd/keystone-glance_high_availability/openstack_ha/controller_node|here]]).

===== Start Cinder-Volume service and the SCSI Target daemon (tgtd) =====
<code bash>
echo "include /etc/cinder/volumes/*" >> /etc/tgt/targets.conf
service openstack-cinder-volume start
service tgtd start
chkconfig openstack-cinder-volume on
chkconfig tgtd on
