Re: Command to find out list of compute nodes

 

Hello,

I resolved the issue, and I feel really silly about the root cause.
Thanks to a suggestion from a member of the community, running the exact
command from /etc/init/nova-compute.conf manually revealed the issue.

root@sonoma:~# date; exec su -s /bin/sh -c "exec nova-compute
--config-file=/etc/nova/nova.conf
--config-file=/etc/nova/nova-compute.conf" nova
Fri Nov 16 13:12:45 PST 2012
Traceback (most recent call last):

Much thanks to everyone for helping out.  I am a step closer to getting my
setup working.
