vmanage 20.9 cluster

[dijix1990]

I made cluster from two vManages and it looks good, sync was ok, but I wanted to try to shutdown one of vManages, after that I can't go to the website the 2nd vmanage because it "vManage server is not ready or temporarily unavailable"

I checked the status, it looked good, I tried to restart and after that...

        Status: running PID:5853 for 896s

Hi @dijix1990 did you solve the problem? Could you share how?

I am facing the same issue, but I have just one vManage and yesterday I stopped to access through GUI interface.

I will be very grateful if you have the solution.

Yes, you need 3 vmanages for cluster, if you have only two vmanages which works in the cluster and one of them is down gui will stop until second vmanage return
