Check this out A tour of BTRFS http://www.youtube.com/watch?v=hxWuaozpe2I And this Dec 2012: SUSE says BTRFS is ready to rock https://www.linux.com/news/enterprise/systems-management/677226-suse-linux-says-btrfs-is-ready-to-rock And this BTRFS improvements in kernel 3.14 http://www.phoronix.com/scan.php?page=news_item&px=MTU4ODA If you´re adventurous, you can run OracleLinux with the Playground repository to test the latest greatest kernel releases... http://www.oracle.com/technetwork/server-storage/linux/downloads/playground-1937163.html No, I´m not running BTRFS but not because of lack of will, but due to lack of enough hard drives to do RAID... And no, this doesn´t specifically answer your questions, but might give you some food for thought :) When/if RHEL will include Kernel 3.14, I have no clue. I guess it will take a lot of time... ;) FC -- During times of Universal Deceit, telling the truth becomes a revolutionary act - George Orwell
