pcs creating cluster fails because of unknown hosts

Question

I am following several tutorials now and all of them have such steps -- authenticate given hosts in pcs and then create cluster. Yet in my case the first step (authenticating) works while the second does not with error stating the hosts are not known/authenticated.

sudo pcs host auth 192.168.4.201 192.168.4.202 

and then

sudo pcs cluster setup my_cluster 192.168.4.201 192.168.4.202 

And for this I get this peculiar error:

Warning: Unable to read the known-hosts file: No such file or directory: '/var/lib/pcsd/known-hosts'
Error: Hosts '192.168.4.201', '192.168.4.202' are not known to pcs, try to authenticate the hosts using 'pcs host auth 192.168.4.201 192.168.4.202' command
Error: None of hosts is known to pcs.

The recommended step (in error message) is exactly what I did. What is missing here for real?

Ubuntu 20.04.2

Answer 1

My colleague looked at it and suggested to check the status of the pcs. It appeared that some node was already running (probably just installing packages creates some default cluster), so we destroyed everything (pcs cluster destroy), started pcsd again and then repeated the steps.

It worked this time.

I hope it was a good move.
