tune2fs(8)
       -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 filesys‐
              tem fragmentation, and to allow system  daemons,  such  as  sys‐
              logd(8),  to continue to function correctly after non-privileged
              processes are prevented from writing to  the  filesystem.   Nor‐
              mally, the default percentage of reserved blocks is 5%.
