Im trying to install and configure a High Availability Pacemaker Cluster in AWS EC2,
But for some reason it is unable to establish authentication between 2 nodes.
OS: Red Hat Enterprise Linux 9 High Availability
The command that I run:
pcs host auth mypc -u hacluster
The error message obtainned is:
Error: mypc: Username and/or password is incorrect
I've tried to change the passwd of hacluster user, using passwd hacluster
I've tried to ssh as hacluster user, which was successfull onto both machines.
The security group is open to all connections.
I can ssh from one machine to another.
