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

    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.

      Sounds like a great use case.

      I’m assuming your nearline drives speak SAS? Are you doing redundant controllers on the backplane for multipathing and for fault tolerance? I’m not sure if bcachefs specifically supports it (or if that would happen at a different layer) but distros in general should support it.

      TCO gets split into CAPEX and OPEX, so you come out ahead on the initial purchase even though it uses more power in the long run, which surely looks better to the business.
