Hi brassow,

I have the cluster up and running successfully. I have set up a clustered
volume group that is visible on both cluster nodes. cman, clvmd, rgmanager
is running on both nodes. However, something in the locking is keeping me
from creating a logical volume...

Thanks for any help you can give, Mike
