You probably have heard of the cool new kid on the file system block, btrfs (pronounced "butter-eff-ess") - after all, Linus Torvalds is using it as his root file system on one of his laptops. But you might not know much about it beyond a few high-level keywords - copy-on-write, checksums, writable snapshots - and a few sensational rumors and stories - the Phoronix benchmarks, btrfs is a ZFS ripoff, btrfs is a secret plan for Oracle domination of Linux, etc. When it comes to file systems, it's hard to tell truth from rumor from vile slander: the code is so complex, the personalities are so exaggerated, and the users are so angry when they lose their data. You can't even settle things with a battle of the benchmarks: file system workloads vary so wildly that you can make a plausible argument for why any benchmark is either totally irrelevant or crucially important.

Very nice reading material. Good mix of technology and drama. Liked it.

I'll be running btrfs soon enough with Ubuntu 9.10 and/or Fedora 12 alphas...
 
Isn't worth using atm/ Performance is pretty low compared to the legendary XFS and the new kid ext4 :P

So I will still stick to ext4 for base and xfs for storage :)
 
oh is that so? i thot performance was as good as if not better than ext4... bootup speed is important to me :P so then i'll stick with ext4
