Denis,

I have no nodes that I'm unable to interconnect. This case is simulated in IgniteDiscoveryMassiveNodeFailTest.testMassiveFailSelfKill()
Introduced in [1].

I’m asking if it is real or supposed problem. Where it was met? Which network configuration/issues could be?

Vladimir,

I'm suggesting to share the log files from the nodes that are unable to
interconnect so that the community can check them for potential issues.
Instead of sharing the logs from all the 5 nodes, try to start a two-nodes
cluster with the nodes that fail to discover each other and attach the logs
from those.

Denis, hi.

      Sorry, I didn’t catch your idea. Are you saying this can happen and
suggest experiment? I’m not descripting a probable case. It is already
done in [1]. I’m asking is it real, where it was met.

Vladimir,

Please do the following experiment. Start a 2-nodes cluster booting node
3
and, for instance, node 5. Those won't be able to interconnect according
to
your description. Attach the log files from both nodes for analysis. This
should be a networking issue.

       Hi, Igniters.


       I wanted to ask how one node may not be able to connect to another
whereas rest of the cluster can. This got covered in [1]. In short: node
3 can't connect to nodes 4 and 5 but can to 1. At the same time, node 2
can connect to 4. Questions:

1) Is it real case? Where this problem came from?

2) If node 3 can’t connect to 4 and 5, does it mean node 2 can’t connect
to 4 (and 5) too?

Sergey, Dmitry maybe you bring light (I see you in [1])? I'm
participating in [2] and found this backward connection checking.
Answering would help us a lot.

Thanks!
