What happens when a process tries to write in that last 5%? do you deny access, or only allow "root" to write there?
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 '/'?
