Thanks Anshum. Will keep track of that. Also the shard is in construction state for long time. I see the size of the index folder inside the newly created cores :
solr/collection1_shard1_0_replica1 solr/collection1_shard1_1_replica1 They are of almost similar size and more than half the size of the original core: collection1. The size of the newly created cores also became constant after the split happened and no longer changing. But still I see the shard status as under construction. As mentioned before, I tried to remove the new shard1_0 and shard1_1 and it created core.properties.unloaded with shardState=construction. Hence I think since my cluster is hung up in construction state for the new shards for longer time, it is not able to delete it. Do you have any inputs on this?
