instead:
# drbdadm down all
# rmmod drbd

> 4. rpm -ivh drbd-0.7.11 NODE2
rpm -Uhv will do the same.
don't forget the _kernel module_ part,
rpm -Uhv drbd-km-whatever...
> 5. Go to run level 3 and let NODE2 come to a consistent state.
instead:
modprobe drbd
> 6. Bring down the NODE1 so that the NODE2 takes over through HA.
do it gracefully: use hb_standby
> 7. Boot NODE1 in single user mode
see above.
> 8. rpm -e drbd-0.7.10 NODE1
> 9. rpm -ivh drbd-0.7.11 NODE1.
> 10. Bring NODE1 back up and let it become the PRIMARY.

don't forget to update the _kernel module_ part,
rpm -Uhv drbd-km-whatever...
> - Is it fine to run 0.7.10 on primary and 0.7.11 on secondary during the
