Open Stack

I am trying devstack on F20 setup with Manila sources.

When i am trying to do
*manila create --name cinder_vol_share_using_nfs2 --share-network-id
36ec5a17-cef6-44a8-a518-457a6f36faa0 NFS 2 *

I see the below error in c-vol due to which even tho' my service VM is
started, manila create errors out as cinder volume is not getting exported
as iSCSI
