Hi,
this is a bug in the product that might have been fixed already:
Connectivity: left-right
we cannot have these sort of connectivity.
In ipa02 there's no replication agreement to ipa01 (for ipaca database).
But as in ipa01 we see that the topology is showing "both" in the
connectivity, I suggest to do export-import "off line" of the database.
Then the topology subtree will be set in ipa02, exactly as in ipa01, and
the topology plugin will create automatically the replication agreement
that is missing now.
export from ipa01 the backend ipaca and re-import it in ipa02. Then, start
the server and check if now it's showing "both" in connectivity at ipa02
side.
Best regards,
German.
PS: If you have a subscription, please create a support case.

Thanks for your answer.
I already tried (on ipa2)
---
$ ipa-csreplica-manage re-initialize --from
ipa1.example.com
---
which failed.
Interestingly enough, the error message is
---
unexpected error: Replication agreement for
ipa1.example.com not found
---
And indeed:
---
$ ipa topologysegment-find ca
------------------
2 segments matched
------------------
Segment name:
ipa2.example.com-to-ipa1.example.com
Left node:
ipa2.example.com
Right node:
ipa1.example.com
Connectivity: both
Segment name:
ipa1.example.com-to-ipa2.example.com
Left node:
ipa1.example.com
Right node:
ipa2.example.com
Connectivity: left-right
----------------------------
Number of entries returned 2
----------------------------
---
The Web UI topology graph doesn't reflect this, btw.
Isn't the 2nd segment obsolete and probably causing my CS replication
issues? Just remove it?
