And if the feature exists, why isn't it mentioned on the wiki page, man pages, etc?
i can't remember where i came across it (possibly lwn.net), but I read somewhere that the main btrfs isn't being updated (fallout from the kernel.org compromise last year). if i understood/remembered it correctly, updates are going to: http://btrfs.ipv5.de/ the main page here was last updated on Feb 9 and mentions kernel 3.2. the https://btrfs.wiki.kernel.org/ was last updated on 23 Aug 2011 and mentions kernel 3.0 craig ps: the only feature in btrfs that would be nice to have in ZFS is 'brtfs filesystem balance' to automatically rebalance sub-volumes and files when you add or remove drives. ZFS doesn't do that...new/updated files get spread across the extra drives in the pool after you add them, but there's no automatic way to re-balance them (it probably wouldn't be too hard hack up a script to copy and rename all existing files if you really wanted to do it...but there would be issues with files that are already open). and another thing that would be nice for both would be the ability to move files between sub-volumes (in the same pool) that was a fast move rather than a copy+delete. -- craig sanders <cas@taz.net.au> BOFH excuse #413: Cow-tippers tipped a cow onto the server.
