What do you mean by 'a cluster' ?

If you mean an actual cluster, how are you doing this and why ?

Hopefully you mean that you just have 3 DCs, if this is the case then
it depends on how you are doing the updates. if you are updating using
packages, then the packages should stop Samba before doing the
update. If you are going to compile Samba yourself, you will need to
use the configure options as originally and stop Samba before running
'make install'.
Either way, I would start with the DC holding all the FSMO roles.
Then the other two DCs, one by one.
