At starting point with tune2fs, things aren't good! $ tune2fs -l /dev/sda1 | grep Reserved tune2fs: Bad magic number in super-block while trying to open /dev/sda1 Couldn't find valid filesystem superblock. Is that OK? I mean does that mean "you have not defined reserve space yet"?

If so, I suggest you look into the "tune2fs" comand. What you seek is basically a filesystem limitation, and the "-m" or "--reserved-blocks-percentage". The filesystem will look like it is 100% full, and report that way to the operationg system with "df" commands, but root will be able to use the remaining percentage to keep the system alive until you throw some stuff away. That's what that option is *for*. On Wed, Oct 23, 2013 at 6:35 AM, Mahmood Naderan <[email protected]> wrote: Hi, >How can I set a global disk usage limit on root folder '/'?
