[Openstack-operators] [Nova] Question about starting nova as service versus directly
So I can start Nova on Ubuntu/Icehouse via *$ sudo python /usr/bin/nova-compute* and it runs fine and stays online but it does not run/stay online if I use *$ sudo service nova-compute start/restart*. I guessed it might have been related to rootwrap but I ran out of time to troubleshoot so I reverted the image to a previously-known good state. Does anyone have an idea why this happens and how to correct? I checked and /etc/nova/rootwrap.conf file looked correct and /etc/nova/nova.conf as well via the root_helper parameter. //adam *Adam Lawson* AQORN, Inc. 427 North Tatnall Street Ste. 58461 Wilmington, Delaware 19801-2230 Toll-free: (844) 4-AQORN-NOW ext. 101 International: +1 302-387-4660 Direct: +1 916-246-2072 ___ OpenStack-operators mailing list OpenStack-operators@lists.openstack.org http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-operators
Re: [Openstack-operators] [Nova] Question about starting nova as service versus directly
Hi Adam, I've seen this happen due to permission issues. Regardless of running with sudo, upstart is dropping to the "nova" user. I usually debug this by setting a shell on the nova user, sudoing/su'ing to nova, then running nova-compute from there. It should die with an error message of the cause.

Upstart is the startup system used by Ubuntu. It's been phased out "in favor" of systemd. ___ Kris Lindgren Senior Linux Systems Engineer GoDaddy From: Adam Lawson mailto:alaw...@aqorn.com>> Date: Friday, November 20, 2015 at 11:16 AM To: Joe Topjian mailto:j...@topjian.net>> Cc: "openstack-operators@lists.openstack.org<mailto:openstack-operators@lists.openstack.org>" mailto:openstack-operators@lists.openstack.org>> Subject: Re: [Openstack-operators] [Nova] Question about starting nova as service versus directly Thanks I will remember this!
