Hi!
We had a very similar issue under SLES 11 SP1 with the LVM RA timing out 
under IO-load. A vgscan took more than 35 seconds unterh that condition 
instead of the usual 0.04.
It is fixed with the newest released packages from Novell, when the filter 
of LVM only looks for /dev/drbd*. During debugging the problem we also 
were advised that it makes no sense at all to monitor a volume group once 
it started successfully.
We do not use LVM as backing device for DRBD any more, so this scenario 
has not been tested.

Mit freundlichen Grüßen / Best Regards
