Working with Kernel Modules

Display all the loaded modules:

lsmod

Save the count of all the loaded modules to /root/current_count.txt:

lsmod | wc -l > /root/current_count.txt

To remove the target_core_module, the iscsi_target_mod dependency must be removed (the -v option can be used to display additional information):

modprobe -r iscsi_target_mod

Validate the modules have been removed:

lsmod | grep target

Install the nfsd module using the modprobe command (the -v option can be used to display additional information):

modprobe -v nfsd

Validate that the module was loaded:

lsmod | grep nfsd

Display information for the nfsd module:

modinfo nsfd

Save the names of the dependencies to /root/dependencies.txt:

modinfo nfsd | grep depends > /root/dependencies.txt

Add the output from lsmod | wc -l to the /root/updated_count.txt file:

lsmod | wc -l > /root/updated_count.txt
