--remove... could be shortened to --rm

failover domains are missing --ls operations.

qdiskd operations is missing --lsheuristics.

Service operations could benefit from sorting. For example:

--lsservices should be the first line.
--*resource  since you add resources before adding services (generally speaking)
--*service   would come next

--addsubservice is a new term here. We generally reference a resource in a service and usage is not super obvious like the other commands.
I would suggest to expand the help text a bit more here, and maybe find a better term. tho I understand it´s not easy to express addresourcetoservice in a short word.
