minus-square@[email protected]linkfedilink10•4 months agoMy 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.

minus-square@[email protected]linkfedilink4•4 months agoIt 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.

minus-squarePossibly linuxlinkfedilinkEnglish2•4 months agoRaid 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
