df -h

       -m reserved-blocks-percentage
              Set the percentage of the filesystem which may only be allocated by privileged  processes.    Reserving
              some number of filesystem blocks for use by privileged processes is done to avoid filesystem fragmenta-
              tion, and to allow system daemons, such as syslogd(8), to continue to  function  correctly  after  non-
              privileged processes are prevented from writing to the filesystem.  Normally, the default percentage of
              reserved blocks is 5%.
