I am hoping you got the version of RedHat Linux wrong as that looks very old and [not supported](https://www.elastic.co/support/matrix). What kind of storage are you using? Some kind of networked storage? ---

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. ---
