??Something wrong on "sed 's!/group!!' ", it did not work.

It did not work. I rebuilt LINUX kernel & LVM after
"./configure --enable-static_link".
I got the same result.

Another big issues came as follow;

I tried to go back to LVM1.0.3, but getting a big trouble.

Q1:  Is it backward compatible from LVM1.1-rc2 to LVM1.0.3 or not?

        I already built the volume from LVM1.1-rc2 then I went back to
LVM1.0.3.
        All of LVM tools are not working as shown in the following console
output.

Q2: How could I remove this volume and rebuild? I do not care about the
data.

During boot or after the boot, I have the following errors;

[root@localhost /]# vgscan -f
