Ocfs2 users - Apr 2010 - ocfs2/o2cb problem with openais/pacemaker

hi!

i'm on debian lenny and trying to run ocfs2 on a dual primary
drbd device. the drbd device is already set up as msDRBD0.

to get dlm_controld.pcmk i installed it from source (from
cluster-suite-3.0.10)
now i configured a resource "resDLM" with 2 clones:
  primitive resDLM ocf:pacemaker:controld op monitor interval="120s"
  clone cloneDLM resDLM meta globally-unique="false"
interleave="true"
  colocation colDLM_DRBD0 inf: cloneDLM msDRBD0:Master
  order ordDRBD0_DLM inf: msDRBD0:promote cloneDLM:start
-> seems to work.


to get ocfs2_controld.pcmk i installed ocfs2-tools-1.4.3 from source.
after adding the resource:
  primitive resO2CB ocf:pacemaker:o2cb op monitor interval="120s"
  clone cloneO2CB resO2CB meta globally-unique="false"
interleave="true"
  colocation colO2CB_DLM inf: cloneO2CB cloneDLM
  order ordDLM_O2CB inf: cloneDLM cloneO2CB

i get the following errors in crm_mon:
=====================================Failed actions:
    resO2CB:0_start_0 (node=app1b.xlhost.de, call=28, rc=1,
status=complete): unknown error
    resO2CB:0_start_0 (node=app1a.xlhost.de, call=38, rc=1,
status=complete): unknown error


the relevant syslog entries:

if i start "ocfs2_controld.pcmk -D" i get:

obviously ocfs2_controld.pcmk can connect to the openais CKPT service and
to dlm_controld.pcmk, which then terminates the connection.
here's the output from dlm_controld.pcmk -q 0 -D:
(the last 6 lines show 3 connection attempts from ocfs2_controld.pcmk!)

i'm pretty lost at the moment, as there's nothing i can find via google
regarding the "core" problem:
1271072439 cpg_joined at 934: Opening control device
1271072439 cpg_joined at 938: Error opening control device: Unable to access
cluster service


any help would be greatly appreciated.
