Hi,
In kernel 2.6.19 and 2.6.18.5 I am facing a problem with modules
dm_mirror and dm_mod not found.
These two modules are part of
Multiple devices driver support (RAID and LVM)
Device mapper support
Mirror target (EXPERIMENTAL)
which I validated.
Compile process built dm-mirror.ko and dm-mod.ko
make install complained that dm_mirror and dm_mod where not found.
Thus I guessed that the modules where incorrectly named.
I only patched Makefile for dm_mirror module name to verify my hypothesis.

However, I checked that modules where in
/lib/modules/2.6.1.9.kernel/drivers/md/
ll /lib/modules/2.6.19/kernel/drivers/md/
total 169
-rw-r--r-- 1 root root 21879 déc 8 15:12 dm_mirror.ko
-rw-r--r-- 1 root root 58701 déc 8 15:12 dm-mod.ko
-rw-r--r-- 1 root root 6727 déc 8 15:12 linear.ko
-rw-r--r-- 1 root root 80744 déc 8 15:12 md-mod.ko
Thus, Makefile script is probably looking into the wrong directory to
find modules dm_mirror and dm_mod
Due to a lack of knowledge, I was not able to determine the actual
directory where make was looking nor to find out in which script part I
could change this.
Any idea ?
