Bcachefs making progress towards getting included in the kernel. My dream of having a Linux native RAID5 capable filesystem is getting closer to reality.

    You’re running local storage for a VM host? Or are you talking more like whiteboxing your own NAS?

    I understand what bcachefs does. I’ve used bcache many years ago to do exactly what you’re describing, albeit for bare metal servers. I’m asking why.

    I’m just trying to understand what the use case would be in 2023 outside of a home lab, given that cost per gigabyte is basically at parity between SSDs and HDDs when you consider TCO (i.e. when you price in the extra power and cooling overhead for the HDDs, failure rates, and such).

      I have a pretty strong usecase for distributed Small/Medium Business bare metal VM hosts. most locations do not need NAS/SAN, and DAS will more than suffice. lower cost hardware with a near-line raided backend and SSD hotcache at FS level seems to be a pretty decent sweet spot.

      obviously this is not some enterprise grade setup and YMMV, but I am pretty interested in a all-in-one FS solution. I am sure others may have more innovative setups where its even more interesting.
