We tested the built in profiles with the default jerasure and Reed Solomon codes., we have not tested SHEC.
The most common issue is the k+m = 18 chucks which is relatively large. If you used one of our built in rules such as ec-by-host-ssd , ec-by-rack-ssd you will need 18 hosts or racks for the 18 chunks to be placed, else the pool will not be active.
