What are the exact package versions you have installed?

pacemaker*
resource-agents
cluster-glue*

so you are using plugin version 0 to start Pacemaker .... That would
explain why /etc/init.d/pacemaker is unable to start ... it is already
started by Corosync.

Strange, that errors are typically related to wrong paths for
initialization of environment and helper functions:

# Initialization:

: ${OCF_FUNCTIONS_DIR=${OCF_ROOT}/lib/heartbeat}
. ${OCF_FUNCTIONS_DIR}/ocf-shellfuncs

DRBD agent has an extra failback check, that may be the reason that it
still works ...

# Resource-agents have moved their ocf-shellfuncs file around.
# There are supposed to be symlinks or wrapper files in the old location,
# pointing to the new one, but people seem to get it wrong all the time.
# Try several locations.

if test -n "${OCF_FUNCTIONS_DIR}" ; then
	if test -e "${OCF_FUNCTIONS_DIR}/ocf-shellfuncs" ; then
		. "${OCF_FUNCTIONS_DIR}/ocf-shellfuncs"
	elif test -e "${OCF_FUNCTIONS_DIR}/.ocf-shellfuncs" ; then
		. "${OCF_FUNCTIONS_DIR}/.ocf-shellfuncs"
	fi
else
	if test -e "${OCF_ROOT}/lib/heartbeat/ocf-shellfuncs" ; then
		. "${OCF_ROOT}/lib/heartbeat/ocf-shellfuncs"
	elif test -e "${OCF_ROOT}/resource.d/heartbeat/.ocf-shellfuncs"; then
		. "${OCF_ROOT}/resource.d/heartbeat/.ocf-shellfuncs"
	fi
fi
