[dm-devel] What is required and what is not?



I am trying to upgrade my system in order to use the device mapper and
the LVM2.

I am trying to upgrade to 2.4.25 my 2.4.20 system. On this system,there
is already a LVM installation and I am using ext3 and jfs as my
filesystems.

It is not clear to me what patches are required and if the patches for
filesystems should be applied or not. And are the 2.4.23 patches
suitable for 2.4.25?

For now, I compiled the Kernel and the dm library. However, I am trying
to create the initrd and I am running into the following errors when
trying to run the lvmcreate 2.4.25 command:

Logical Volume Manager 1.0.8 by Heinz Mauelshagen  17/11/2003

So, I then ran the depmod -ae as following:

[root einstein boot]# depmod -ae 2.4.25

What is missing?
