Yep, you've found a bug.  The problem is that you've got a Win-98 extended
partition, (ID=0x0f).

When LVM goes through to determine the validity of the partition you
specified, it does not recognize that  you have any extended partitions,
thusly, does not scan for any logical partions on an extended partition.

Try this patch.  (WARNING!! I have not tried this patch, so use at your own
risk!!!))
To apply this patch, cut-it-out of your E-Mail, and type the following
cd {your-lvm-source-tree}; patch -p1 <{win98-patch-filename}

Where {your-lvm-source-tree} is the name of the directory you untared the
LVM sources, and {win98-patch-filename} is the directory/filename of the
patch file listed below.  (don't type the braces in the command line above)

Hi,

The same on RedHat 6.0 - same config.

What was going wrong here ?
What should I do ?

I'd like to use the LVM for testing. I'm primary working in the
AIX-support-center.
My special field there are LVM-problems :)


Thanks with warm regards,
Udo Weber
***************************************************************************

Maybe I put a dot (".") too much between the lines in the last email :)

But the prob should be the same, I read the answers from Heinz, now I
think here is realy
a problem.

Thanks,
Udo
