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.
