      Description

      Hello,

      We have a 3 node Solr cluster (ensemble) with apache-zookeeper 3.5.5.

      It works fine until we need to restart one of the nodes. Then all the content of the collection gets deleted.

      This is a production environment, and every time there is a restart or a crash in one of the services/servers we loose lots of time restoring the collection and work. 

      This is the way we start the nodes:

      su - ipls004p -c "/applis/24374-iplsp-00/IPLS/solr-8.3.0/bin/solr start -cloud -p 8987 -h s01vl9918254 -s /applis/24374-iplsp-00/IPLS/solr-8.3.0/cloud/node1/solr -z s01vl9918254:2181,s01vl9918256:2181,s01vl9918258:2181 -force"

      This is the zoo.cfg:

      1. The number of milliseconds of each tick
        tickTime=2000
      2. The number of ticks that the initial
      3. synchronization phase can take
        initLimit=10
      4. The number of ticks that can pass between
      5. sending a request and getting an acknowledgement
        syncLimit=5
      6. the directory where the snapshot is stored.
      7. do not use /tmp for storage, /tmp here is just
      8. example sakes.
        dataDir=/applis/24374-iplsp-00/IPLS/apache-zookeeper-3.5.5-bin/temp
      9. the port at which the clients will connect
        clientPort=2181
      1. the maximum number of client connections.
      2. increase this if you need to handle more clients
        #maxClientCnxns=60
        #
      3. Be sure to read the maintenance section of the
      4. administrator guide before turning on autopurge.
        #
      5. http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance
        #
      6. The number of snapshots to retain in dataDir
        #autopurge.snapRetainCount=3
      7. Purge task interval in hours
      8. Set to "0" to disable auto purge feature
        #autopurge.purgeInterval=1
        4lw.commands.whitelist=mntr,conf,ruok
