I'm a network engineer with 8 years of experience, but I've never really gotten into data storage. Recently, while setting up some redundant services on my homelab, I ran into issues with persistent storage and realized I need to understand data integrity better. I have many questions such as what to do if data becomes corrupt, how to handle file locks in databases, and the differences between syncing and backing up data. I want to learn from the ground up—should I take some database administration classes, or where else should I start? Any guidance on key concepts or resources would be appreciated!

Check out Ceph for a practical solution. I've been using it for about a decade and it’s been pretty reliable. It offers a clustered file system, block storage for VMs, and object storage—all of which are redundant. Plus, it's free if you don’t need support, and it works with various hardware setups!
You might want to start by exploring storage fabric and partitioning. Netapp is a solid choice for getting your head around things, and picking up a book on Database Fundamentals will help you understand concepts like LUNs, masking, and the ACID properties of transactions.
