I wrote about btrfs 8 years ago.
Since then, it has made its way into several small to mid-end storage solutions (more NAS inclined solutions) including Rockstor, Synology, Terramaster, and Asustor. In the Linux world, SUSE® Linux Enterprise Server and OpenSUSE® use btrfs as the default OS file system. I have decided to revisit btrfs filesystem to give some thoughts about its future.
Have you looked under the hood?
The sad part is not many people look under the hood anymore, especially for the market the btrfs storage vendors are targeting. The small medium businesses just want a storage which is cheap. But cheap comes at a risk where the storage reliability and data integrity are often overlooked.
The technical conversation is secondary and thus the lack of queries for strong enterprise features may be leading btrfs to be complacent in its development.
