Hi all,

i have a strange Error on one of my Clusters. 

ERROR: tengine_stonith_callback: Stonith of saput1d1 failed (-7)... aborting
transition.
info: abort_transition_graph: tengine_stonith_callback:402 - Triggered
transition abort (complete=0) : Stonith failed

Due to that, the suriving node counts the other node as unclean(offline)

CIB:
property $id="cib-bootstrap-options" \
        dc-version="1.1.2-2e096a41a5f9e184a1c1537c82c6da1093698eb5" \
        cluster-infrastructure="openais" \
        expected-quorum-votes="2" \
        no-quorum-policy="ignore" \
        last-lrm-refresh="1283325763" \
        node-health-strategy="migrate-on-red"

SBD Primitive:
primitive rsc_sbd_daemon stonith:external/sbd \
        meta target-role="Started" \
        operations $id="rsc_sbd_daemon-operations" \
        op monitor interval="15" timeout="60" start-delay="15" \
        params sbd_device="/dev/mapper/mpathh_part1"

and unter /etc/sysconfig/sbd
SBD_DEVICE="/dev/mapper/mpathh_part1"
# The next line enables the watchdog support:
SBD_OPTS="-W"

for /etc/init.d/boot.local
i used modprobe softdog
as described under: http://www.linux-ha.org/wiki/SBD_Fencing


At the beginning everthing worked fine - now i have this Error. Any ideas?

Kind regards,

Rainer
