The problem is, there is no cluster anymore just single nodes, because
kubernetes teared all nodes down. And each single node won't start on its
own, because of the orddict error. And IIRC riak-admin cluster replace
works only on a node which is already running, right?
Currently my problem seems to be solved. After 13 hours of fixing our
cluster I missed one node to reintegrate into the cluster but it was
already a load balancing target.
Can I assume, the /var/lib/riak/ring folder is not data-critical? So after
clustering all new nodes with all old data, the data integrity is preserved?
