i shaved this thread a little, since it gets confusing. Hope i kept the
interesting bits.
The errors related to "Unable to find request for serial xxx" mean
that the cert is tracked by certmonger, but there is no corresponding
LDAP entry cn=xxx,ou=ca,ou=requests,o=ipaca on the local LDAP server.
Is the replication still working between your two masters?
"ipa cert-show" broken on ipa2 often points to an out-of-date
certificate in /var/lib/ipa/ra-agent.{pem|key}. The content should be
the same as on the renewal master, and also the same as in the entry
uid=ipara,ou=People,o=ipaca (which should be replicated and identical
on all the masters, except if you have replication issues).
Replication appeared to be working, however, I did server maintenance
today, ipa1 and ipa2 got upgraded and rebooted. ipa1 works fine, ipa2
does not come up properly:

You need to have a look at krb5 logs to understand why kerberos failed
to start. Please check
https://www.freeipa.org/page/Troubleshooting/Kerberos for more
information.
Turns out that kerberos starts when started manually with systemctl:

Looks bad.
So yes, the replication of the suffix o=ipaca seems broken. In a
deployment with CA, the ldap server contains 2 different suffixes, one
for the IdM data (your base DN as defined in /etc/ipa/default.conf) and
another one for the CA, below o=ipaca.
You can have a look at
https://www.freeipa.org/page/Troubleshooting/Directory_Server for
replication troubleshooting, but the repl issue could be a consequence
of kerberos server not starting.
I checked the troubleshooting pages and carried out the steps described in
there, but my system (ipa2) appears to be ok as far as the steps go.

The root cause appears to be the wrong IPA RA certificate in ipa2's
LDAP, right? I guess this has to fixed by manually importing the
proper certificate using ldapmodify, similar to the procedure
described in [1]?
It is possible to manually modify the IPA RA cert in ipa2's ldap server
but this won't solve the replication issue. It will however allow you to
run ipa cert-show.
Unfortunately, it doesn't (ipa2):
---
ipa: ERROR: Certificate operation cannot be completed: EXCEPTION (Invalid
Credential.)

Works ok on ipa1.
I'm unsure how to proceed here. My obvious problem is ipa2 not getting
upgraded properly:
