See % below.
coredump parameter: -m mink | minm | min%
Create a minfree file in the current savecore directory indicating that savecore should maintain at least the specified amount of free space in the file system where the savecore directory is located. The min argument can be one of the following:
k
A positive integer suffixed with the unit k specifying kilobytes.
m
A positive integer suffixed with the unit m specifying megabytes.
%
A % symbol, indicating that the minfree value should be computed as the specified percentage of the total current size of the file system containing the savecore directory.
The savecore command will consult the minfree file, if present, prior to writing the dump files. If the size of these files would decrease the amount of free disk space below the minfree threshold, no dump files are written and an error message is logged. The administrator should immediately clean up the savecore directory to provide adequate free space, and re-execute the savecore command manually. The administrator can also specify an alternate directory on the savecore command-line.
Incorrect:
Not C: Separate ZFS volumes must be used for the swap area and dump devices.
