Vgchange : error code -22

Hi there!

I have read all the documentation in the LVM-package, but i can't find a sollution to my problem in the HOW-TOs.

I run kernel 2.4.13 with Slackware 8.0. I tried to patch the rc.S with the LVM-patch, but it looks like the patch is allready applied in the distribution.

When i run : vgchange -v -d -a y i get the following output, but I don't really know what the problem is.

Any help is aprichiated.
