Hi,I got 4 data nodes,1 master node and 1 search node
For example,At first,the data was equally saved in 4 data nodes
node1 1.6TB
node2 1.6TB
node3 1.6TB
node4 1.6TB
Since My disk is 2TB and it is almost full,I delete some index to get more
storage
after deleting the data nodes are like below
node1 1TB
node2 1TB
node3 1TB
node4 1TB
after a few days, I found the data is not equally saved in each node anymore
node1 1.1TB
node2 1.1TB
node3 1.1TB
node4 1.6TB
node 4 is almost full
I don't know why,and is there anyway to rebalance data in each data node

How many index/shards/replicas do you have?

index number depend on how many days past,the index name is the day epoch.
because we use elasticseach for log storage
shard number is 8
replica is 1

Try increasing the number of shards - maybe to 20 or 40.

Also, higher shards will help with the new indexes but not the existing ones.
You can use the API to force ES to move shards off your ‘full’ disk over to the new one.
Auto-balancing for data size should be on by default if you are running a newer version of ES.

So you have 16 shards (8 primary and 8 replicas). On a 5 nodes cluster, this should rebalance automatically.
Are you sure your 5th node actually joined the cluster ?
