Open Stack

Hello and thank you for the help.
I was able to move forward on my problem, without finding a satisfactory solution.
Normally, I have 2 servers with the role [glance] but I noticed that all my images were on the first server (in / var / lib / docker / volumes / glance / _data / images) before the reconfigure, none on the second. But since the reconfiguration, the images are placed on the second, and no longer on the first. I do not understand why. I haven't changed anything to the multinode file.
so, to get out of this situation quickly as I need this openstack for the students, I modified the multinode file and put only one server in [glance] (I put server 1, the one that had the images before reconfigure), I did a reconfigure -t glance and now I have my images usable for instances.
I don't understand what happened. There is something wrong.

Is it normal that after updating the certificates, all instances are turned off?
thanks again

Franck
