You can use the sudo, without any problems.

you need /usr/local/bin/drbd-gui-helper* for sure. Note the wildcard,
there's a suffix that changes with every version

For pacemaker you need at least these I think:

/usr/sbin/crm_attribute
/usr/sbin/crm_mon
/usr/sbin/crm_resource
/usr/sbin/crm_standby

Maybe I'll compile the whole list one day.

yes, the

    java -jar DMC-....jar  --help

gives you a list of options, so for example

    java -jar DMC-0.8.12.jar --op-mode=ro
    java -jar DMC-0.8.12.jar --op-mode=op

starts it in readonly or operator mode and it is not possible to change it
to the administrator mode.

Yes, there is --no-upgrade-check option and --no-plugin-check option, if
you don't want contact the linbit servers.
