The idea behind the balance is to spread the used space across all your drives evenly. So you would usually run it after adding a new drive. It's also useful if your disk has a lot of space allocated to either data or metadata and you want to return to a more reasonable default. Josef has a patch to do this more dynamically that we're fixing up (hopefully for 2.6.38-rc2). In general, it isn't something that you want to do very often. -chris -- 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
