I set that key in both controller and compute still no luck Le 26/04/2013 18:26, Darragh O'Reilly a écrit : its not really obvious, but I believe the iscsi_ip_address needs to be set in the nova.conf on the **controller** - just want to check you did it there. ___ Mailing list: https://launchpad.net/~openstack Post to : openstack@lists.launchpad.net Unsubscribe : https://launchpad.net/~openstack More help : https://help.launchpad.net/ListHelp ___ Mailing list: https://launchpad.net/~openstack Post to : openstack@lists.launchpad.net Unsubscribe : https://launchpad.net/~openstack More help : https://help.launchpad.net/ListHelp
Re: [Openstack] [Grizzly] cannot attach volume to instance due to wrong iscsi target
No I'm running just one iscsi target service:
root@leonard:~# netstat -antp | grep 3260
tcp0 0 0.0.0.0:3260 0.0.0.0:* LISTEN
8927/tgtd
tcp6 0 0 :::3260 :::*LISTEN 8927/tgtd
Here is my cinder.conf:
root@leonard:~# cat /etc/cinder/cinder.conf
[DEFAULT]
rootwrap_config = /etc/cinder/rootwrap.conf
api_paste_confg = /etc/cinder/api-paste.ini
iscsi_helper = tgtadm
volume_name_template = volume-%s
volume_group = cinder-volumes
verbose = True
auth_strategy = keystone
state_path = /var/lib/cinder
lock_path = /var/lock/cinder
volumes_dir = /var/lib/cinder/volumes
sql_connection = mysql://cinder:grizzly@leonard/cinder
rabbit_password = grizzly
iscsi_ip_address=192.168.203.103
So how can the compute node try to reach the public interface of the
controller? How can it possibly even know this IP?

I believe you are using both iscsitarget and tgt in your
configuration, that's why you are getting this issue.
Stop any one target and mark the current target in cinder.conf
iscsihelper=
Example : iscsi_helper=tgtadm
Then restart the all the services, hopefully this will work.
Thanks

Exception during message handling
As we can see, the compute node tries to reach the API interface
(192.168.202.103) of the controller node. Of course, it cannot, since
the compute node only knows the data and the management subnets.
Is this the default behaviour and I'm missing a parameter somewhere?
I set this key in nova.conf:
iscsi_ip_address=192.168.203.103
but still no luck
any clue?
yours,
