Sean Reifschneider Subject: btrfs is a ways off... |
That sort of article is still a ways off. I had attempted to do some serious use and testing of btrfs a few months ago, but at that time the ability to delete snapshots was not implemented.
They've just implemented this and it'll be in 2.6.33 (Probably Fedora 13 and Ubuntu 10.10, I've been told not in the upcoming 10.04).
At this point I'd say the comparison I'm using is that btrfs has just caught up with ZFS circa 2005. It's got very cool features and sounds very promising, but it's very young. The latter is not really something you want in a file-system. ;-)
File-systems are just hard things to get right. I'm reminded of ext3, which was just a set of changes to ext2, and that took around 4 years to get out and another couple to stabilize.
