                    IndexMetaData tribeIndex = tribeState.metaData().index(index.getIndex());
                    clusterStateChanged = true;
                    if (tribeIndex == null || tribeIndex.getState() == IndexMetaData.State.CLOSE) {
                        logger.info("[{}] removing index {}"; tribeName; index.getIndex());
                        removeIndex(blocks; metaData; routingTable; index);
                    } else {
                        // always make sure to update the metadata and routing table; in case
                        // there are changes in them (new mapping; shards moving from initializing to started)
                        routingTable.add(tribeState.routingTable().index(index.getIndex()));
