I've upgraded to newest kernel 3.1.2 but problem is not fixed. After reboot btrfs works fine to maybe few hours but after that system stats to choke on sys load, system becames unresponsive, and backups to btrfs becames extremly slow. Anything you want me to check so you can diagnose the problem - before I will return to ext4? blue on graph is sys load. It should not be visible at all. Something is seriously wrong with btrfs http://img265.imageshack.us/img265/1416/37248826.png I use snapshots for every important directory (after each backup) so there quite lot of them but this is a reason why I use btrfs. # btrfs sub list /backup|wc -l 7651 -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
