SOLVED:

after reading the code for ocfs2_controld.pcmk i figured the missing
control device on my machines was "/dev/misc/ocfs2_control".

i added a /etc/udev/rules.d/52-ocfs2.rules file with following content:
KERNEL=="ocfs2_control", NAME="misc/ocfs2_control", MODE="0666"

the control device is automagically created now an mounting ocfs2
volumes works.

best regards,
