Commands mkfs.ext4 and tune2fs have this option:
-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 fragmentation, 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%.
See the last sentence. By default normal users can't fill the entire
space. Use tune2fs to change options for an existing file system.
