Hi,
I am running GA bits of Folsom. I am running a two node setup where the first
node is the controller+compute node that has Cinder running as well. The second
node is merely a compute node. I am seeing an issue while booting an instance
from Cinder volume on both the nodes. The "nova boot" operation fails while
spawning the instance with the following error.
[00mProcessExecutionError: Unexpected error while running command.
[00mCommand: sudo nova-rootwrap /etc/nova/rootwrap.conf iscsiadm -m node -T
iqn.2010-10.org.openstack:volume-3ac4b027-905e-4318-a74e-2bdf94f5d887 -p
192.168.150.96:3260 --rescan
[00mExit code: 255
[00mStdout: ''
[00mStderr: 'iscsiadm: No portal found.\n'
[00m
I had successfully created a Cinder volume with a valid image on it.

I even tried to discover the iSCSI targets. But it returns with "no records
found".
I then looked into to MySQL database for Cinder and looked at the entries,
specifically "provider_location" and it looked just fine. 192.168.150.96 is the
node where I have controller and cinder running.

I manually tried to discover the iSCSI targets and it couldn't find any.

I am not sure what's wrong with my setup. Any help is greatly appreciated.
Thanks
