Hi Ahmed,

Could you check whether the log files are present in the folder /var/log/nova/nova-compute.log on the compute node? Can you also confirm regarding the status of all the necessary daemons related to nova and other components deployed on the cloud controller node?

Thanks
Krishnaprasad Narayanan

Subject: Re: Command to find out list of compute nodes

Hi Narayanan,

Awesome, thank you.  There reason I was not seeing the "nova-compute"
listed is because it did not launch on the compute node.  I did a manual start of "nova-compute" on the compute node, and I do see it listed on the control-node but with "XXX" State.

root@bodega:~/ahmed/new_guide# nova-manage  service list

Binary 		Host 	Zone             Status 	State	Updated_At
nova-network 	bodega 	nova             enabled 	:-) 	2012-11-15 23:49:28
nova-scheduler 	bodega 	nova             enabled 	:-) 	2012-11-15 23:49:28
nova-compute 	sonoma 	nova             enabled	XXX 	2012-11-15 23:46:46
<= compute-node

What I don't understand is even though nova-compute is listed on the control-node, the service is not running on the compute node.  That does not seem right.

root@sonoma:~# service nova-compute status nova-compute stop/waiting root@sonoma:~# date;  service nova-compute start Thu Nov 15 15:48:08 PST 2012 nova-compute start/running, process 2785 root@sonoma:~# service nova-compute status nova-compute stop/waiting root@sonoma:~# ps aux | grep nova
root      2810  0.0  0.0   9384   924 pts/0    S+   15:49   0:00 grep
--color=auto nova
root@sonoma:~# service  nova-compute status nova-compute stop/waiting root@sonoma:~# 

There are no log entries in the log files on compute-node or control-node.
 Any ideas please?


Thank you,
Ahmed.
