Austing PowersRebuilding software RAID array is very easy when you have your mdadm.conf file at hand, but when you find yourself in a situation without backup of that little config file, e.g. after reinstalling the system or when your migrate disks to the new server, it can be a bit daunting.

Recently I had to reassemble two software RAID1 arrays one small Debian server after OS reinstall. So, there were four hard drives in total and to avoid mix-up and data loss, I had to find out which disk belonged which RAID array. Examining each drive with mdamd provided me with the necessary information.

root@localhost:~# mdadm --examine /dev/sdd1

There are several possibilities/levels depending on what you want to do:

Implement Servlet API ServletContextListener interface in your application.

I spent a lot of time trying to figure out how to setup Thorntail/Wildfly JAX-RS apps to allow async operations. Most configuration examples created one problem or another. I finally came across the idea that you could simply activate it by registering a ServletContextListener and changing the setting on the fly during startup.

package com.platform28.service.asyncmessaging.restapi;

import javax.servlet.FilterRegistration;
import javax.servlet.ServletContext;

Storing Google Cloud Platform (GCP) Credentials in AWS Secrets Manager for Apache Airflow to connect to BigQuery

This took me a while to figure out by looking at the code & docs. Most Google searches were directing me to useless articles (usually about storing the creds in GCP Secrets Manager)

1. Create a service account (or other account)
2. Create a new key and download the JSON file
3. Open the file & copy the entire JSON into the clipboard
4. Create an AWS Secret (name it appropriately, let's say airflow/connection/mydag/gcp
   • Set the key to extra
   • Set the value to the contents to:
