Hi Ludwig, Petr,
Presently I have noticed that disabling a segment, using `ipa
topologysegment-mod realm replica1-to-replica2
--enabled=off` does not have effect on the way the data is replicated.
I mean that if we have the following tolopogy:
master <-> replica1 <-> replica2
on which server did you apply the mod ?
On master. It reproduces though even in a situation with the topology
replica3 <-> master <-> replica1 <-> replica2 and you disable the
replica1-replica2 segment on replica3 (quite expectedly)
and disable one of the segments, one would expect the changes
implemented on master would not be replicated to other nodes (or do I
misunderstand the concept of disabling a segment?). However, in
reality any changes in master do get replicated despite the segment
well, I think disabling should be temporary, you want to disconnect
for some time. eg for debugging, not deleting the agreement
completely, I would allow this.
Is it a correct behavior?
The second question is: if disabled segments should not let the
changes through, then we probably should implement a check for
topology disconnection in similar way as `ipa topologysegment-del`
does. I mean, whenever a user tries to disable a segment, the plugin
should probably check whether it disconnects any of the nodes.
