Hi,
I want to change the ip addresses (ip v4) that nodes use to discuss (gossip).
I'm trying to migrate from ipv4 to ipv6 for those communications. I tried to
follow a similar procedure as the one used at CASSANDRA-8382
<https://issues.apache.org/jira/browse/CASSANDRA-8382?focusedCommentId=14259892&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-14259892>.
However it doesn't work as expected. When I do the change on the first node,
nodes seems to not see each other, if I trust nodetool :
on first node :
Datacenter: s1
==============
Status=Up/Down
|/ State=Normal/Leaving/Joining/Moving
-- Address Load Tokens Owns Host ID
Rack
DN 10.10.12.19 ? 256 ?
dab24e23-4b42-438e-9070-7994e329e868 i10
UN 2a01:c940:a5:2005:0:0:0:18 244.35 MB 256 ?
03c558ec-add9-4dcd-bf2b-a1b28575e06b c10
on second node :
Datacenter: s1
==============
Status=Up/Down
|/ State=Normal/Leaving/Joining/Moving
-- Address Load Tokens Owns (effective) Host ID
Rack
DN 10.10.12.18 244.24 MB 256 100.0%
03c558ec-add9-4dcd-bf2b-a1b28575e06b c10
UN 10.10.12.19 244.11 MB 256 100.0%
dab24e23-4b42-438e-9070-7994e329e868 i10
I can see in the first node logs that it tries to handshake with node 2,
however I can't see neither error in node 1 logs nor information in node 2 logs.
Of course, I'm trying to find a procedure that does not cause any downtime of
the whole cluster.
Any idea ?
