Solandra cluster configuration for fault tolerance

[Adrian]

I have a 4 node test cluster running Cassandra 0.7.4, and I installed
Solandra from the git repository. I took each node offline one at a
time and started it back up with Solandra and I could index
documents. However if I kill one of the servers I cant write to other
servers.

I get this error message back:
Error 500 org.apache.solr.client.solrj.SolrServerException:
java.net.ConnectException: Connection refused

org.apache.solr.common.SolrException:

I took a look at the keyspace L and I saw that it has Replication
Factor: 1. Would increasing this value to 2 make it so other servers
could take over if 1 goes down? Or is that bug a solr thing? Are
there any other things in the configs I should worry about?

Yes it's the replication level.

If you can change this in the Cassandra-cli. Check the Cassandra wiki.

The settings can be helpful if you are running into problems. But the defaults are sane.
