Quickly get up to 5% more disk space from your ext3 volumes

I’ve seen many websites that have pretty much the same ext3 performance tips, but I just came across this one today that had something very useful on it. It turns out that the ext3 filesystem by default reserves 5% of the disk space of the volume just in case the volume fills up.┬áThis would allow the system to continue running and allow the root user to still log in and clean things up.
