A possible way to increase free Disk Space on
Linux
One of the servers's hard disk I do administrate is filling up for
some time. In order to increase the amount of free space I
remembered that there was a system reserved space for system repair
purposes like executing fsck, etc. etc. By default Linux has a
certain amount reserved for this purposes if I remember correctly
this is usually 5% of all the disk space available. To check the
amount if pre-reserved disk space on a linux installation you might
use let's say the cmd
# tune2fs -l /dev/sda1
You'll get your occupied space by default in blocks which is a bit
unconfortable, however if not familiar please read what is

In my case I've decided to reduce the pre-reserved system space to
2%. To achieve that I've executed the following command
# tune2fs -m 2 /dev/sda1
The benefit I've got was 2 extra gygagybates of disk space. Which I
guess is quite a good gain.
