mdconfig —
configure MEMORY disks
mdconfig |
special_file
512-byte-blocks |
The mdconfig command configures memory disk devices. It
will associate the special file special_file with a
range of user-virtual memory allocated by the mdconfig
process itself. The mdconfig command should be run in
the background. If successful, the command will not return. Otherwise, an
error message will be printed.
To "unconfigure" the memory disk, just kill the
background mdconfig process started earlier.
mdconfig /dev/md0c 2048
&
Configures the memory disk md0c with one
megabyte of user-space memory.
The special device will become inoperative if the
mdconfig process is killed while the special device is
open.
