Btrfs—brief for “B-Tree File System” and steadily pronounced “butter” or “butter eff ess”—is essentially the most superior filesystem current within the mainline Linux kernel. In some methods, btrfs merely seeks to supplant ext4, the default filesystem for many Linux distributions. However btrfs additionally goals to offer next-gen options that break the straightforward “filesystem” mould, combining the performance of a RAID array supervisor, a quantity supervisor, and extra.
We’ve excellent news and dangerous information about this. First, btrfs is a wonderfully cromulent single-disk ext4 alternative. However when you’re hoping to interchange ZFS—or a extra complicated stack constructed on discrete RAID administration, quantity administration, and easy filesystem—the image isn’t fairly so rosy. Though the btrfs challenge has mounted most of the evident issues it launched with in 2009, different issues stay basically unchanged 12 years later.
A type of initiatives we’ve been listening to about for years. I believe most distributions nonetheless default to ext4 – apart from Fedora.
