Hi Sebastian Thank you - unfortunately when I specify the mount point, the result is the same. The drive has devid 3, I was (forced by failure) playing with the drives quite a lot. Seems like I am hitting all the nice issues with btrfs :) Lubos Lubos -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
