Followup on this part: Because you're running in Cloud mode, trying to share index data between replicas *will* have problems. There's no way to work around those problems. It would completely explain the "write.lock" issues. Cloud mode ABSOLUTELY requires that each node has its own copy of the data, and prefers to have full locking support from the OS. Many NFS implementations cannot provide full locking support, which is why running Solr on NFS is not advised. Thanks, Shawn
