The first log I found is as above. I tried everything I found on Google to solve this problem, but it failed.

```
Afterwards, I deleted and reinstalled the Elasticsearch, and the logs I found were as follows.
It also tried everything, but it didn't succeed.
Thereafter, two logs are generated alternately.
I wanted to replace the hard disk, but I couldn't because I couldn't do that.
Please let me know if the hard disk is a problem or if there is another solution.

I think this is the problem
> memory locking requested for elasticsearch process but memory is not locked
Is [this option](https://www.elastic.co/guide/en/elasticsearch/reference/current/_memory_lock_check.html) turned on? You'll have to see why the memory lock isn't working in your environment.

```
My settings are as follows.
I checked if there is a problem with the license, but it is working as basic.
And I have one more piece of equipment of the same spec and it's working well there.

From the second logs, it looks like ES was up and running and status is green, what is the issue there (after re-installation) ?
> Lock held by another program: /data/elasticsearch/data/nodes/0/snapshot\_cache/write.lock
From the first log, it looks like there was some snapshot in progress which was holding the lock, have you tried deleting that lock file post restarting ES ?
