Setting number_of_shards but couldn't resolve host

Elastic Stack Elasticsearch
1

when I set the shards number, it throws such problem:
curl -XPUT 'l0.62.179.32:9200/my_index/pretty' -H 'Content-Type: application/json' -d'
{
"settings": {
"number_of_shards" : 2,
"number_of_replicas" : 0
}
}
'
curl: (6) Couldn't resolve host 'l0.62.179.32'

Could anyone give me some advice?

Is the first character in the IP address a digit? It does not look like a 1.

Oh, Yeah. You are so smart. Thanks a lot.

But it still has the problem like this:
SZX1000355659:/home/2:9200/my_index/_settings?pretty' -H 'Content-Type: application/json' -d'

{
"number_of_shards" : 2,
"number_of_replicas" : 0
}'
{
"error" : {
"root_cause" : [
{
"type" : "remote_transport_exception",
"reason" : "[node-3][10.62.183.178:9302][indices:admin/settings/update]"
}
],
"type" : "illegal_argument_exception",
"reason" : "Can't update non dynamic settings [[index.number_of_shards]] for open indices [[my_index/QF5ARy2VQ6G0t8BzZEI86g]]"
},
"status" : 400
}

Once an index has been created, you can not change the number of shards, only the number of replicas.

Thanks. If so, how we scale out the storage of primary shards?

Let us keep this discussion to your other thread: How does the elasticsearch expand capacity and shrink capacity？

Ok, thanks a lot.
