Hi All ! I'm testing Solr 7.5 with TLOG replicas on SolrCloud with 5 nodes.
My collection has shards and every shard has 3 TLOG replicas on different nodes. I've noticed that some replicas stop receiving updates from the leader without any visible signs from the cluster status. (all replicas active and green in Admin UI CLOUD graph). But indexversion of 'ill' replica not increasing with the leader. It seems to be dangerous, because that 'ill' replica could become a leader after restart of the nodes and I already experienced data loss. I didn't notice any meaningfull records in solr log, except that probably problem occurs when leader changes. Meanwhile, I monitor indexversion of all replicas in a cluster by mbeans and recreate ill replicas when difference with the leader indexversion more than one Any suggestions? -- Best regards, Vadim
