Search not working: "Not enough nodes are up to service this request." [JIRA: RIAK-1738]

[oktie]

I have a 100-node Riak cluster running (version 2.0.5) with default settings (except for search=on and increased ring size). At some point, search (Yokozuna / Solr) stopped working, with any query returning "Not enough nodes are up to service this request.". All the nodes are running fine and the key value store is functioning properly, so it seems like a search/Solr issue but I haven't been able to figure out what could the problem be. I've tried restarting all the nodes but it didn't help.

Status? Seeing the same thing but with 3 nodes. It worked last week.

When the issue is happening, could you attach to the riak console (riak-admin attach) on one of the nodes and run

rp(riak_core_node_watcher:nodes(riak_kv)).

(Dot at the end important, ^G q to exit), And check if all of your nodes are in the list.
