Attach volume with LXC failed

[Samuel Hassine]

Hi,

Attaching a volume to an LXC instance does not work:

1. euca-create-volume -s 20 -z nova
2. euca-attach-volume -i i-00000001 -d /dev/vdb vol-00000001

I got the following error in nova-compute:

http://pastebin.com/JhtcUp5d

(nova.compute.manager): TRACE: Command: sudo iscsiadm -m node -T iqn.2010-10.org.openstack:volume-00000001 -p 77.67.61.181:3260 --op new

This is an issue of sudoers badly configured: it is missing iscsiadm.
What distribution are you using ? Which version of the packages ?
