If you lose quorum on your ZK ensemble, SolrCloud will go read-only, and
indexing will not be possible.  Solr will remember the last clusterstate
that the ZK database held and will attempt to keep serving queries using
that information.  Whether or not that succeeds will depend on whether
your Solr servers stay operational.

If you restart a Solr server while ZK has no quorum, then I'm not sure
what happens.  It probably doesn't start correctly and may need another
restart after ZK is restored.
