# With DRBD9 there is a new behavior when trying to become primary, without the second node reachable.
# In this case the command "drbadm -- --overwrite-data-of-peer primary $resource"
# will end with an error "refusing to be primary while peer is not outdated".
# A workaround is to use instead the commands
# drbdadm del-peer $resource
# drbdadm primary $resource --force
# We assume when "drbadm -- --overwrite-data-of-peer primary $resource"
# exits with non-zero exit code it is this issue so we try the other commands
# because we hope things won't get worse this way (but we are no DRBD experts)
# cf. "Dirty hacks welcome" at https://github.com/rear/rear/wiki/Coding-Style
