[Opendnssec-user] mysql and replication

My issue is less (or not) related to OpenDNSSEC and more to MySQL and
replication, but I still hope someone with more experience or related to
the development can help me with it.
I try to build high availability solution with OpenDNSSEC (ODS) - two
servers (signers) running ODS, each one connected to separate HSM. Only one
of the signers will be active at a time, which means when one machine is
running ODS, on the other ODS will be down. Now I have MySQL as part of the
setup and master-master replication is configured between them, always
running on both. The replication is working well when I test it manually
using test database or if I manually create new table in the existing KASP
database (used by ODS). When updating the KASP database using ODS
(ods-ksmutil) triggering rollover or generating more keys I never see the
data replicated to the second machine.

Any ideas what am I missing?

Do any of you use such HA solutions? What setup works well for you?
