I am installing ICp 2.1.0.1 and I received an error at the TASK

[master: Waiting for MariaDB service to start] msg: The MariaDB component failed to start.

After this msg the installation completed with failed status. We are installing ICp with 3 Masters, 3 Proxies and 2 Workers. We have 1 IP for VIP master and 1 for VIP proxy. I tried to install multiple times and all installations got the same error.

For prior issues with that error, the correct db admin password was not used. So check the db user and password to resolve issue.

Would you validate whether each master host was able to access port 3306 on the other hosts?

If you run with .. install -vv | tee -a install-log.txt, do you get additional details as well?

  • Would you validate whether each master host was able to access port 3306 on the other hosts? - Yes, we disabled the firewall at the all linux server used in the installation. We did the install using the verbose option but did not show any clear error. – Christiano Monteiro Feb 27 '18 at 00:37

The error was solved by following the steps below.

Check whether kubelet is running:

  • Log in to your master node.

  • Run the following command to check kubelet status:

    systemctl status kubelet

  • If kubelet is not running, run the following command to get the logs:

    journalctl -u kubelet &> kubelet.log

We found the error in the kubelet.log log:

Error: failed to run Kubelet: Running with swap on is not supported, please disable swap! or set --fail-swap-on flag to false.

We found this troubleshoot in this link, and the solution at the ICP issue 4651.
