Hello Mr. Kees,
Thanks for your response!
My setup is
Openstack Node 1 -> controller + network + compute1 (Liberty Version)
Openstack node 2 --> Compute2
Ceph version Hammer
I am using dell storage with following status
DELL SAN storage is attached to both hosts as
[root@OSKVM1 ~]# iscsiadm -m node

Since in my setup same LUNs are MAPPED to both hosts
i choose 2 LUNS on Openstack Node 1 and 2 on Openstack Node 2

*Can you please help me to know if it is correct configuration as per my
setup?*
After this setup, i am trying to configure Cinder and Glance to use RBD for
a backend.
Glance image is already stored in RBD.
Following this link http://docs.ceph.com/docs/master/rbd/rbd-openstack/
I have managed to install glance image in rbd. But i am finding some issue
in cinder configuration. Can you please help me on this?
As per link, i need to configure these parameters under [ceph] but i do not
have different section for [ceph]. infact i could find all these parameters
under [DEFAULT]. Is it ok to configure them under [DEFAULT].
CONFIGURING CINDER
<http://docs.ceph.com/docs/master/rbd/rbd-openstack/#configuring-cinder>
OpenStack requires a driver to interact with Ceph block devices. You must
also specify the pool name for the block device. On your OpenStack node,
edit/etc/cinder/cinder.conf by adding:
[DEFAULT]
...
enabled_backends = ceph
...
[ceph]
volume_driver = cinder.volume.drivers.rbd.RBDDriver
rbd_pool = volumes
rbd_ceph_conf = /etc/ceph/ceph.conf
rbd_flatten_volume_from_snapshot = false
rbd_max_clone_depth = 5
rbd_store_chunk_size = 4
rados_connect_timeout = -1
glance_api_version = 2
I find following error in cinder service status
systemctl status openstack-cinder-volume.service
