Re: [linux-lvm] 2.4.20-pre4 and lvm-1.0.5

[Heinz J . Mauelshagen <Heinz.Mauelshagen@t-online.de>]

Donald,

your system seems to be running LVM fine without any other modules loaded
and LVM 1.0.5 driver linked into the 2.4.20-pre4 kernel.

Did the "cd LVM/PATCHES;make;cd $KERNEL_DIR;patch -p1 TheLVMPatch" run
show any problems?

Do you say that pvscan etc. even fail when /lib/modules/2.4.20-pre4
is in the module path and *no* modules get loaded at all?

Did you ever retry with a clean build
"make clean&&make dep&&make bzlilo&&make modules&&make modules_install"
and an error free depmod run?

Regards,
Heinz    -- The LVM Guy --
