Let's say we have thousands of block storage devices in NetApp through ONTAP, a service which offers block storage (this question intends not to be focused on NetApp nuances) that were created in Kubernetes using default database/app solutions (e.g. official MariaDB, official MongoDB, etc.), but for whatever reason now they are not available anymore in Kubernetes, and we just have dangling block storage.
So, having this sheer amount of storage without any particular organization behind it: Is there an existing software to programatically identify from which database or application is this block storage storing information?
I understand the whole requirement would be to mount the block storage programatically for all elements, and then perform the actual task of identifying which kind of database/app has created the structure of that data we are seeing. Reasonably, the most complicated part would be the "identification" process.
Therefore, the main question is: Is there any software available that could help us identify which block storage was once storing, for instance, a MariaDB database, or any other database? Otherwise, I guess we will have to develop a software specifically for this, and this would be eminently time-consuming.
