Btrfs (and more recently also XFS) supports on-demand, batch dedup which doesn't have any of the downsides of ZFS's always-active dedup. This is an implementation issue, not a categorical problem of block (or extent) dedup.
- matheusmoreira 4y agoBtrfs is like an almost perfect file system. If only it had proper stable support for software RAID. It's weird that it still doesn't have it, I thought enterprises cared about that.
- nicolaslem 4y agoIt has proper stable support for many kinds of software RAID: https://btrfs.readthedocs.io/en/latest/Status.html https://btrfs.readthedocs.io/en/latest/Status.html
- matheusmoreira 4y agoExcept RAID6 which is the one I want. From your link: https://btrfs.readthedocs.io/en/latest/btrfs-man5.html#raid56-status-and-recommended-practices https://btrfs.readthedocs.io/en/latest/btrfs-man5.html#raid5... Also, reading stuff like "mostly OK" in a file system doesn't inspire confidence.
