Elasticsearch can not started：failed to find global metadata

wangdwcsd · October 19, 2021, 12:23am

After the master node is restarted, it cannot be started. The following errors are always reported in the log，Is there any way to enable the Elasticsearch instance to load metadata？

error log：

Please don't ping people that aren't already part of the topic

Are you using docker?
What does your config look like.

wangdwcsd · October 19, 2021, 12:34am

I not use docker，Deployed on X86 physical machines

The configuration is as follows：

cluster.name: tyrzelacluster
node.name: tyrzela01-01
node.master: true
node.data: false
path.data:  /data1
path.logs: /ela/ela01/log
bootstrap.memory_lock: false
bootstrap.system_call_filter: false
network.bind_host: 0.0.0.0
network.publish_host: 152.56.158.142
http.port: 9200
transport.tcp.port: 9300
discovery.seed_hosts: ["152.56.158.142:9300","152.56.158.143:9300","152.56.158.144:9300"]
cluster.initial_master_nodes: ["152.56.158.142","152.56.158.143","152.56.158.144"]
#thread_pool.write.queue_size: 1500
indices.breaker.total.use_real_memory: false
cluster.max_shards_per_node: 2000
#xpack.security.enabled: true
#discovery.zen.fd.ping_timeout: 60s
#discovery.zen.fd.ping_interval: 10s

warkolm · October 19, 2021, 12:38am

Don't use both of these, just set network.host.

This is not a great idea, it'll likely lead to inefficient memory use.

What do the Elasticsearch logs show, from startup to this error?

wangdwcsd · October 19, 2021, 12:43am

I didn't find any other errors

Please upgrade, 7.2 is EOL and no longer supported.

I tried to start the instance under version 7.4.1 today, but I also reported the same error。
Can I try starting with 7.7 or later？

warkolm · October 19, 2021, 12:53am

7.7 is the oldest currently supported version, however 7.15 is latest and recommended.
