hi all.
i am having problem removing several loadable modules from a linux 2.6 kernel (redhat5)
i have entered them into a blacklist but it didnt help. removing manually is forbidden due to dependencies that i cannot see. just for example, say i dont use ext3 fs or lvm for that matter and dont want it to load on next boot. ext3 module is used by 2 other modules but their names arent specified in the lsmod command. (means its from the kernel itself?)
what i want to do is to create a new smaller kernel without most of the modules and without recompiling kernel.

will appreciate any help
oren.

See the manpages for modprobe(8). The option you want is -r.

I'm not sure how much luck you are going to have removing modules like ext3.

As for lvm, if you're really not using it, try simply turning off the lvm2-monitor service. (That might prevent the module from loading at boot time -- not sure on that.)

Can you explain why you're trying to do this? Are you expecting to see a big system resource savings?

Welcome to LQ.

If I remember right, things are like this :
You cannot boot into 'lvm' and thus have a
small boot partition to take care of that.

The boot partition is ext3.

And why in the first place do anything to save about 100 kB ?

hi anomie, knudfl, thanks for your quick response.
unloading with the -r option is not good enough because i dont want those module to be loaded from boot. i could wait for boot and schedule a script to unload them but it seems illogical if i can simply remove them from load sequence in first boot.
my goal is to create a smaller kernel by removing all unnecessary module like sound, video, bluetooth etc. rebuilding the kernel is not an option at hte moment because of redhat's support. as for the lvm module, this was just an example to a module which cannot be removed by -r because it has dependencies which cannot be seen in the lsmod command. (even tough i didnt use ext3 or lvm)
