Hello @rvb_n,

Seems that you had the 7.3.1 and you want to came back to the 7.3.0, to start your node you can change or delete the data directory \< Warning : all the document in it will be lost \>

In elasticsearch.yml change :

`path.data: /var/elasticsearch`

NB: you will have to create a new directory tree that are owned by elasticsearch
