I am trying to get a working openstack liberty in one of our dev servers that has minimal configuration and has ubuntu 14:04.
All the components looks good and I was able to create instance and view the dashboard too.
Now, I am trying to create a volume and this is where I am facing an issue.
We have a node that has a disk 'sda' with 8GB and we followed the steps listed here to prepare the disk. https://eatpeppershothot.blogspot.sg/2016/04/use-real-block-storage-backend-for.html
output of lsblk
NAME FSTYPE LABEL MOUNTPOINT
sda xfs
└─sda1 LVM2_member
Then we followed the standard documentation http://docs.openstack.org/liberty/install-guide-ubuntu/cinder-storage-install.html
On Controller node
**root@dev-controller:~/scripts# cinder service-list**

By default all the volumes were listed under "nova" zone but we changed it to different node while trying things out.
Command to create volume cinder create --volume_type lvm --display_name testvol 1 --availability-zone dev-osd2 cinder create --volume_type lvm --display_name testb 1
The 'cinder create' command works but 'cinder list' command shows that the volume is in error state. Both of these commands end up in error state.

I have checked and made sure that all the database connect string are correct and that the host are able to connect to the controller. RabbitMQ is fine too.
