newfs(8):
-m free-space
The percentage of space reserved from normal users; the mini-
mum free space threshold. The default value used is 5%. See
tunefs(8) for more details on how to set this option.
tunefs(8):
-m minfree
This value specifies the percentage of space held back from nor-
mal users; the minimum free space threshold. The default value
is set during creation of the filesystem; see newfs(8). This
value can be set to zero, however up to a factor of three in
throughput will be lost over the performance obtained at a 5%
threshold. Note that if the value is raised above the current
usage level, users will be unable to allocate files until enough
files have been deleted to get under the higher threshold.
