[Eckhard Kosin]

Hi Alasdair,

I'm sorry to mail directly to you,  but I tried three times without
success to post the below listed mail to linux-lvm at redhat.com , it
doesn't arrive their ;={{  Perhaps you can check the reason, post my
mail to our thread in the list, and last but not least, do you have an
answer to my problem?

     Thank you very much, have a nice day

           Ecki
