Hi,

I am unable to start Elasticsearch on docker. Refer following screenshot for error.

 ![Screenshot from 2021-02-15 17-15-55](https://us1.discourse-cdn.com/elastic/original/3X/c/f/cfff85e4d1e578f068aa34e3f1eeb450b709a9b1.jpeg)

Can anyone help me to solve this error.  
Elasticsearch version - 6.4.3

Thanks

Best to copy/paste the text of the error, it seems the error mentions two causes and this most likely cause from incorrect definition on docker side with the volume used for data folder:

1. `/usr/share/elasticsearch/data` is read-only
2. `/usr/share/elasticsearch/data` is already used/locked by another node (another docker container)

Can you check both those points

1. `docker inspect <container_id>` would show if a read-only volume is used (or just check with the docker CLI options you used, or docker-compose service defintion for example...)
2. Secondly you should check that the volume is only used by a single container. For example just use a different/new volume for that container and check if the error goes away

Thanks

Hi @Julien ,

Thanks for reply.

I am able to solve issue by deleting **node.lock** file.

Thanks & Regards
