Hello Christine,

I googled a bit and some doc[1] says that TC_PRIO_INTERACTIVE maps to value 6, whatever that is.
Assuming that value of 6 is the same as the "priority value", Corosync traffic should go into band 0, because
TOS values of 0x10 and 0x14 have "priority value" 6, too. The page[2] on lartc.org says that, too.

That means that at least when pfifo_fast is used, there's no need for iptables rules or tc filters to prioritize Corosync traffic manually.
