    LVM has snapshot support 🤨? Is this a new thing?

    ZFS and BTRFS also have other uses like RAID-like functionality and detecting and possibly correcting data corruption - with only one drive these features are not as useful though.

    Yes they are. Regarding data integrity (bit rot or read/write errors) though. Regarding data backup, no.

    BCacheFS is new to the mainline kernel and does much the same as ZFS and BTRFS, when distros start offering this as a supported option it’s probably a good idea to use this, kind of unfinished at the moment though.

    I think kernel support is planned for version 6.7… I think.

      Yeah it’s included in kernel 6.7. Still probably too new to really use as they are still working on certain features like erasure code/parity.

      Without another drive it can’t rebuild data, so all it can do is detect corruption not correct it.

        Yeah, that is still too unsable in real world scenarios.

        Still, it’s great that people are doing this from scratch, not just build on what Oracle throws at us. I do wish they address the RAID5/6 issue properly, not just throw it under the carpet like BTRFS. I did hear that they are working on fixing RAID5/6 in BTRFS, but I haven’t looked at how far things are. I still use it with mdadm in the background for the array.
