这有帮助吗?

man mkfs.ext3
-m reserved-blocks-percentage
   Specify the percentage of the filesystem blocks reserved for the
   super-user.   This  avoids  fragmentation, and allows root-owned
   daemons, such as syslogd(8), to continue to  function  correctly
   after non-privileged processes are prevented from writing to the
   filesystem.  The default percentage is 5%.
