Most of my testing was done 2 years ago. So in this 'kind of production' system I did not try it. But if I knew that it was faster, perhaps I could have used it. Anyone has statistics for such a replace and the time it takes? Also, can replace be used when one device is missing? Cant find documentation. eg. btrfs replace start missing /dev/sdXX TM -- 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
