Everything you listed looks fine to me. In my experience, extending
logical volumes usually goes well (regardless of distro). I have only
seen things go wrong from folks attempting to shrink their file systems.

enter reboot
(just before I hit enter I realized that I had just added the disk for
this test and did not update the initrd & zipl ...
Durrrr ... I know better than that but did it three times the last time
I was testing this a few weeks ago .... )
so it does work fine .... lvextend + ext2online can grow a file system
while mounted .... even after a boot works fine ...
:) so sorry .. all ...

No we are a RedHat shop and have migrated to running: RHEL4.4 , 4.6 ,

I've been testing mostly on our RHEL4.6 code level as that's our
largest
deployed level at this time.
I'll test again later this afternoon and update to the list.
Thanks,
Paul..
So there's your problem then, need to switch to SLES10 SP1 ;-)
