Why Dummy? Better use db2.

Better ERR_CONFIGURED, this looks like a serious setup problem.

return? Above it was exit. Or is there more to be done on stop?

Hmm, this is an attribute which should be on the master
right? Using crm_config for that looks wrong. I think
that it should go into the node status.

What does this do? It is run in the background from the
start action, but it is not waited on (no exit code check)

You can leave out "$0 ~". It is going to work this way too,
but otherwise it does not look very awk :)
Also, since it goes to eval below, better add single quotes around
/HADR_PEER_WINDOW/ {printf "HADR_PEER_WINDOW='%s'\n" ...

Better move (and indent) the return to the line below

How about taking the body of the loop to a separate function
and then splitting it into more functions. If possible.
It is just too long.
