thanks for the pointer. i updated the ra to support it. i tried to
reproduce the simple setup to test the functionality, skipping the clvm
resource and running the ping_pong test against a "normal" partition.
here my config.

node node1
node node2
primitive data-test ocf:heartbeat:Filesystem \
        params device="/dev/mapper/mpathcp1" directory="/data/test"
fstype="gfs2" \
        op monitor interval="120s"
primitive dlm ocf:pacemaker:controld \
        op monitor interval="120s" \
        meta target-role="Started"
primitive gfsd ocf:pacemaker:controld \
        params daemon="gfs_controld.pcmk" args="-g 0" \
        op monitor interval="120s" \
        meta target-role="Started"
clone data-test-clone data-test \
        meta interleave="true" ordered="true"
clone dlm-clone dlm \
        meta interleave="true" ordered="true"
clone gfsd-clone gfsd \
        meta interleave="true" ordered="true"
colocation colo-gfsd-WITH-dlm inf: gfsd-clone dlm-clone
order order-data-test-AFTER-gfsd inf: gfsd-clone data-test-clone
order order-gfsd-AFTER-dlm inf: dlm-clone gfsd-clone

as may imagine, the ping_pong test still fails. stracing the ping_pong
test gives the followinig output:

write(1, "lock at 0 failed! - Function not"..., 45) = 45
fcntl(3, F_SETLKW, {type=F_UNLCK, whence=SEEK_SET, start=0, len=1}) =
-1 ENOSYS (Function not implemented)
write(1, "unlock at 0 failed! - Function n"..., 47) = 47
fcntl(3, F_SETLKW, {type=F_WRLCK, whence=SEEK_SET, start=0, len=1}) =
-1 ENOSYS (Function not implemented)

running the ping_pong test on a local filesystem (ext3 in this case)
works. if i mount manually mount the gfs2-partition with the mount
option "localflocks" again the test succeds. 

since the test works for other people, i'm rather clueless what i'm
doing wrong. here some details about my system:

any advices? maybe this a problem with this specific kernel version?

TIA
