Strange shard counts

Elastic Stack Elasticsearch
#1

Hi,

I checked the index stats by visiting

http://localhost:9200/raw/_stats?pretty

{
"_shards" : {
"total" : 10,
"successful" : 5,
"failed" : 0
},

There are totally 10 shards, 5 successful, 0 failed. But where are the
missing 5 shards? Any insights?

Thanks a lot!
Jingzhao

If you have a single node cluster, they are unassigned.

Hi, Jörg,

Yes, I got that now. On my development PC, I changed things in
elasticsearch.yml to

index.number_of_shards: 1
index.number_of_replicas: 0

The stats output becomes:

"_shards" : {
"total" : 1,
"successful" : 1,
"failed" : 0
},

Thanks a lot for your help!

The 5 that were not assigned is that because you set a limit on the max
shards per node?

Hi, Ajay,

shards per node?

I don't see any limit on the max shards per node. I did a Google search and
cannot find such parameter. I cannot only see memory limits. Mind sharing
more details?

Thanks a lot for your help.

See the section on "Total shards per node".
