[DRBD-user] DRBD 8.0 life cycle

[Paul D. O'Rorke]

I have to pass on my thanks and respect.

I have been running a 3 node "Stacked" replication set on 8.9.6 for some 
years now.  This weekend I finally bit the bullet and installed 9.11.0 
from the Ubuntu 20.04 LTS  repos on new hardware and I am blown away at 
how simple and efficient the move was.

 1. Define the resource
 2. create-md
 3. bring it up
 4. Go home and drink tea...

wow - it "just works" and how!  I came in this morning the happy owner 
of a newly replicated set of 16 VMs and I have paid not a cent to you guys.

The very least I can do is say thanks.  Thanks for the great work and 
thanks even more for making it publicly accessible.
