To pile on: If you're talking about pointing two Solr instances at the _same_ index, it doesn't matter whether you are on NFS or not, you'll have all sorts of problems. And if this is a SolrCloud installation, it's particularly hard to get right.
Please do not do this unless you have a very good reason, and please tell us what the reason is so we can perhaps suggest alternatives.
