4 Running LD

A fresh MinixLLD partition is created by the following command (to be executed in the command directory):

mk_lld [ Device] [ Number of Blocks]

For example, to create a 400 MByte partition (the standard block size is 4 KByte) on disk rsd1d the following command would be issued:

mk_lld /dev/rsd1d 100000

There are two ways of running LD: First, the experiment can be linked in with the MinixLLD executable. In this case, it is sufficient to simply execute the MinixLLD executable (the standard executable is called lld and can be found in the LLD directories). Second, to run LD interactively the following command needs to be issued in the unix directory:

./startup [ LD executable] rfs

For example, to run the standard LD executable (with concurrent ARUs) the following command would be issued:

./startup ../LLD_with_ARUs/lld rfs

The individual commands of the interactive shell are listed in a table in the source file for rfs ( unix/rfs.c).

Note that superuser privileges are necessary for above commands to work.
