After restarting Cassandra , some of nodes are missing in nodetool status
Hi All,
we are running apache Cassandra 3.1.0 on AWS in multi-region nearly around
200 nodes.
after restarting each node I am seeing some of the nodes are missing from
the nodetool status (not UN or DN they are completely missing). after
couple of restarts, I am seeing them back.
Please help me if I am missing something at the configuration side
Thanks
Nanda

Did you replace any of the nodes which are missing in the nodetool status
?
Regard’s

Ok, I will check. Can you please be more specific? like what to check about
the token range and if we find any mismatch what to do next.

I would suggest you to check the token ranges of all the nodes and see if
any of the nodes have similar token ranges.

Is 3.1.0 a typo? Is it really 3.1 or 3.11.0 ?
