I waited some days, but nobody wrote something about dd and raw
devices...

I read the dd man pages on two Linux Systems - and the newest
one from the fileutils Version 4.1:
http://www.gnu.org/directory/All_GNU_Packages/fileutils.html
But I couldn't find any note about (problems with) raw devices.

Grey, would you give me a hint? Anybody else? I'm asking here
because I used dd to find out more about my problems with
lvm and raw devices (for Oracle RAC):

Thanks in advance, Eike
