dear ovirt user community,
I can't sort out an ovirt issue I got with cinder for weeks, I hope
someone could give me a clue...
From mi ovirt manager 4.1, I can create and delete a cinder volume or
attach and detach a cider vomume from an ovirt VM.
The problem is I never had been able to launch an ovirt VM with a cinder
volume attached to it.
I just got a simple message from ovir web gui: "Failed to run VM
centoscinder (User: admin@internal-authz)".
what i am using is
a RDO newton release of openstack. the backend of cinder is a local lvm,
and the openstack VMs can use the cinder volumes from other compute node.
from the ovirt 4.1 fedora 24 server:
[root@rhevf24 ~]# rpm -qa | grep ovirt-engine-4
ovirt-engine-4.1.0.4-1.fc24.noarch
ovirt-engine-setup-plugin-ovirt-engine-4.1.0.4-1.fc24.noarch
[root@rhevf24 ~]#
from the ovirt server , through the iscsiadm command, I can see for
example the 2 disks attached to 2 diffents openstack instances,
but not the one I just created from ovirt which is attached to nothing ,
from the openstack rdo point of view.
[root@rhevf24 iscsi]# iscsiadm -m discovery -t sendtargets -p 192.168.122.36
192.168.122.36:3260,1
iqn.2010-10.org.openstack:volume-f4c6c55c-e383-4781-8d24-d41b55870d29
192.168.122.36:3260,1
iqn.2010-10.org.openstack:volume-58844340-741e-45da-9aa7-b0ed08391df3
as I said previously From ovirt I can create /delete in cinder and
attach/detach volumes to ovirt VMs I don't get any troubles with that.
----
in ovirt engine.log almost nothing , except it can't aquire lock.. but
in openstack cinder, and with tcpdump I get more informations.
tcpdump give me when ovirt intent the iscsi connection something like:
json.key == "os-initialize_connection"
{. "os-initialize_connection" : {. "connector" : { }, },}
and I get from "tail -f /var/log/cinder/volume.log" :
2017-03-07 16:45:06.889 3856 ERROR cinder.volume.targets.iscsi

2017-03-07 16:45:06.891 3856 ERROR oslo_messaging.rpc.server
InvalidInput: Invalid input received: Connector doesn't have required
information: initiator
So it looks like I didn't get or I can't provide the initiator name I
want to be connected to.
Cinder can't obviously guess which one I want. that's more or less
what's the cinder's logs are telling me.
I have searched for a long time in internet, it looks like at least
since ovirt 3.6, cinder is ont anymore an issue, and can even be
integrated with a ceph back end to ovirt...
cinder model an client are installed in the ovirt server...
Somebody get any clue to tell ma where i made a mistake in the cinder
integration with ovirt , which seems to be correct regarding the
create/delete attach /detach volume behavior...
Thank you
Herve
