Hi,
sorry for the last mail, I don't know why but something was left of this
mail.
Here now (I hope so) the complete mail once more and for insurence also
the same as
attachment:
******************************************************************
Hi LVM-specialists,
I'm new here the Linux-LVM-array. This means I was downloading all
needed software+patches, compiled successfull and also installed without
erors on my IBM-Thinkpad (300 MHz PII, 128 MB RAM, 8GByte HD).
I have all my LINUX-stuff on several extended partitions.
Now at first some generally questions (I don't found an answer for this
in the docu):
Is it possible to create a PV on a extended partion or do I need only
primary partions ?
I think pvcreate writes something at the top of the physical volume (
whole PV or partion).
Do that works well with other OS-formated parts of the same hdisk ?
If the first question is no, forget the rest of this mail!
If it should works please help. Here are all infos related to my
problem:

The same on RedHat 6.0 - same config.
only one different output:

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
