I have a single node ElasticSearch Cluster in local. I am unable to start elasticsearch service getting this error:

All directories in elasticsearch have rwx permission.
What is the solution for this?
Unix flavour : Red Hat 4.8.5

Edit:
RedHat Version : 7.5

I am hoping you got the version of RedHat Linux wrong as that looks very old and not supported. What kind of storage are you using? Some kind of networked storage?

4

OS: Red Hat 4.8.5-28
I am using HDD.

5

Yes , I am using a remote VM

6

That is not a supported OS so I have no idea what effects that could have. I would recommend upgrading to a supported one to eliminate this being the cause.

7

Okay. Thank you, I'll do that.

@Christian_Dahlqvist. Sorry I got it wrong. RedHat Version is :7.5
All files in elasticsearch folder have rwx permission. And there is no orphan java process. what else could be the issue?

9

Deleted data folder and rebooted VM. Now it is working
