Watchdog should be enabled

We can check existing cluster configuration using:

pcs property show

However, if one of the value is shown as:

have-watchdog: false
maintenance-mode: false
no-quorum-policy: ignore
startup-fencing: true
stonith-enabled: true

Then it is better to change it via:

pcs property set have-watchdog=true


Accessing cluster via web interface

Access cluster via https://<hostname-or-ip>:2224/ and login via appropriate user such as hacluster.
