thermodynamics - Entropy change of an irreversible process

I know that there's a lot of questions about this subject but I couldn't find specifically what I want to ask so here it is:

One of the consequences of Clausius's theorem is the fact that for any transformation we have $dS\geq\delta Q/T $

my question is if my system goes through an irreversible process then do I get $dS>\delta Q/T $ or equality is also possible?

thanks for any clarification.
