Do you have access to:
https://access.redhat.com/documentation/en-us/red_hat_enterprise_linux/7/html/high_availability_add-on_administration/ch-nfsserver-haaa

It seems that it describes (extensively) building a NFS server on pacemaker.

DRBD for CentOS7 was never in epel, but in elrepo.CentOS8 repos  are still building up,  so stick with EL7 if possible.Otherwise you will have to build DRBD from source.

I was also thinking about it and I still don't have the time to test a HA NFS with contractd to keep tcp sessions replicated and avoid any disruption to the end-clients.
