So, what do you see if you run "ctdb scriptstatus" on an unhealthy
node?  This should give you the reason that it is unhealthy.  If it
says "monitor cycle never run" then please try "ctdb scriptstatus
startup".

I'm guessing that you've restarted CTDB on both nodes after making the
netmask change?   There's a small chance that you've used "ctdb
reloadips", which is missing some logic to deal with change of
netmasks... but it hasn't bitten anyone yet, to my knowledge, so is low
on the priority list.

Not rocket science.  Just a bit harder than setting up Samba.  More
dependencies...
