I am not realizing how to get the default number of shards per node or
the maximun one, because I think I am having 'red' status since I have more

Sorry you're having issues! To the best of my knowledge, there's no
maximum number of shards for a single server; if anything, it would be
limited by memory available.Red means some shards can't be loaded, but this can be caused by corrupt
or missing shard data. Do you have any elasticsearch logs that might help
here?-Jordan
One additional note I forgot to mention - file count limits could be a
cause of your problems here.
Pretty much all linux distros ship with a default 'open file' limit of
1024. This is a really bad default for elasticsearch, especially if you
have many shards. You can see file-count related errors in ES's logs for
things like "Failed to create shard" for example:
Failed to create shard, message [IndexShardCreationException[[exampl
e][1691] failed to create shard]; nested: IOException[directory
'/mnt/btrfs/data/ela
sticsearch/nodes/0/indices/example/1691/index' exists and is a directory,
but cannot
be listed: list() returned null]; ]]
You can find more details about checking this file count limit here:
