@Cindy What version are you using?

Hi~ My version is elasticsearch 7.10.2, opendistroforelasticsearch-1.13.1.
Thanks a lot.

I’m not an expert on this particular aspect of Elasticsearch (perhaps others can chime in), but it seems like this has replication and loss of communication with a shard. The ‘peer recovery’ part is the giveaway. Seems to be lots of information floating around about that. Hope it gives you a place to start looking.
