I was using DRBD in a 2-node cluster, primarily for redundancy.  Our 
Data Storage needs have outgrown our need for redundancy and I now need 
both nodes of the cluster to function independently.  I don't know how 
much overhead is added to the storage subsystems by DRBD but would like 
to remove the DRBD layer from the mix on the old primary node if 
possible.  Is there a way to remove DRBD and reclaim the low-level 
device without reformatting would be my only question.  At this point I 
do not have a spare server capable of holding all of the data from the 
old primary while I reformat, and I would rather not have to take the 
time to do a complete backup of 2.7TB and then restore after a 
reformat.  (It's actually more of taking the time to restore since we do 
make regular backups of the data.)  Is there an easy way to do what I 
need?  (Should probably mention the old primary is running the 0.7 code.)
