Fuel for OpenStack

Node seen offline by Fuel but still can be pinged

Asked by eighilaza

Hi,
I have a node that is seen as offline by the Fuel Master even though I can ping it and ssh to it from that same Fuel Master.

[root@fuel ~]# fuel node list

[root@fuel ~]# ping 10.20.0.17

It was seen as online a few hours ago and I didn't make any changes to my hardware since then. Any suggestions on how to fix this please?
Thanks,

Hi,
Thanks for your reply
The service mcollective is running and the I didn't see any errors in the log files. I only have lines like this

It seems to be still receiving and sending heartbeats. Yet the Fuel Master sees it offline.

Sorry for previous message.

Please check nailgun agent on node-15.
It reports to master node node status.
And please check /var/log/docker-logs/nailgun/api.log on master node

thanks for you reply
After trying for while, I had to give up and re-install without figuring out what went wrong

Can you help with this problem?
