    My only gripe with btrfs is that I've had systems come down from a single drive failure in raid quite "often" when compared to other FS.

    ZFS is a ram hog but I always could do a live resilvering without downtime.

    btrfs's RAID features are not production-ready, and at this point I doubt they ever will be. See:

    https://en.wikipedia.org/wiki/Btrfs#Implemented_but_not_recommended_for_production_use

    https://wiki.archlinux.org/title/Btrfs

    https://www.phoronix.com/news/Btrfs-Warning-RAID5-RAID6

    ZFS is definitely more robust.

    It is true for raid 5 & 6. Raid 0, 1, and 10 are supposed to be production ready. I use raid 10 only with btrfs, anything else and I use zfs or mdadm.

    I wouldn't go above two disks

    You have to avoid the raid types is lists as not ready. Looks like facebook uses btrfs without issues

    [–] [email protected] 2 points 3 months ago

    Raid 1 is stable. The problem is that btrfs has performance issues with resilvering a large amount of data. That isn't something that can be fixed as it is a design flaw.

    Maybe bcachfs will be production ready at some point
