Solr clusterstate.json corrupted. Manual restore possible?

I am stuck with having null value for the range in clusterstate.json (attached below)

"shard5":{
        "range":null,
        "state":"active",
        "replicas":{"core_node1":{
            "state":"active",
            "core":"Web_shard5_replica1",
            "node_name":"domain-name.com:1981_solr",
            "base_url":"http://domain-name.com:1981/solr",
            "leader":"true"}}}},
    "router":"compositeId"},

I tried to use zookeeper cli to change this, but it was not able to. I tried to locate this file, but didn't find it anywhere.

Can you please let me know how do i change the range from null to something meaningful? i have the range that i need, so if i can find the file, maybe i can change it manually.

My next question is - can we have a catch all for ranges, i mean if things don't match any other range then insert in this shard..is this possible?

Kindly advice.

Here is an example of manually editing and updating clusterstate.json in zookeeper using zkcli.sh provided with Solr.

  1. Download clusterstate.json:

    zkcli.sh -z zk-host-name -cmd getfile /clusterstate.json clusterstateLoca.json

  2. Edit the downloaded closterstateLocal.json and save it

  3. Remove stale clusterstate.json from ZK

    zkcli.sh -z zk-host-name -cmd clear /clusterstate.json

  4. Upload modified clusterstate.json to ZK:

    zkcli.sh -z zk-host-name -cmd putfile /clusterstate.json ./clusterstateLocal.json

I resolved the above problem by creating duplicate shards (replicas) & used the below for its creation - 

http://domain-name.com:1981/solr/admin/collections?action=CREATE&name=image&numShards=5&replicationFactor=2&maxShardsPerNode=2

Maybe it will help someone else as well....I have a custom ranking algorithm not sure if that is the thing that influenced this, but then it seems solved now
