Is it actually usable or just a meme file system?

Yeah, it's usable. You can do some fun stuff with snapshotting, if you're interested in using it.

Unless you care about snapshotting your filesystem or have storage that's measured in Petabytes, it's not really a big deal.

>>59820042
it's the default file system on openSUSE

>>59820042
it's junk.

use OpenZFS instead http://zfsonlinux.org/ though the best implementation of OpenZFS is on SmartOS/illumos https://www.joyent.com/smartos

>>59820058
This. Also note that Btrfs has worse performance than ext4.

It's bretty good. I have been using its compression and SSD wearleveling features on an industrial 4GB SSD embedded box for years. There were some early out-of-freespace issues, but I haven't run into that in a long time. I also don't usually fill the disk to capacity either, which caused a lot of the freespace failures.

Last year the RAID5/6 code was found to have major problems killing data during scrub operations due to a race condition. There were a series of patches posted in early February on the Btrfs mailing list which might fix the problem. The patch series is up to its 5th iteration as of a week ago, so it might see a commit to a tree for testing soon.
