Ahhhh.
We changed the way monitors that return OCF_NOT_RUNNING were handled to still
require a stop under most conditions.
I've added "not managed" to the list of exceptions:
diff --git a/lib/pengine/unpack.c b/lib/pengine/unpack.c
index 308258d..6dc44fd 100644
--- a/lib/pengine/unpack.c

case PCMK_OCF_NOT_RUNNING:

+ if (is_probe || target_rc == rc || is_not_set(rsc->flags,
pe_rsc_managed)) {
result = PCMK_LRM_OP_DONE;
rsc->role = RSC_ROLE_STOPPED;
Look for this in 1.1.13-rc2

Hmmm, you'd have to take that up with the crmsh maintainers.
