Using data paths mounts net usable space net total space types – How to solve this Elasticsearch error

Briefly, this error occurs when Elasticsearch is unable to determine the usable or total space on the data paths. This could be due to insufficient permissions, a full disk, or a misconfigured data path. To resolve this issue, you can check and adjust the permissions on the data paths, ensure there is enough disk space, or verify the data path configuration in the Elasticsearch settings. Additionally, you may need to check the health of your hardware as this error can also be caused by a failing disk.

This guide will help you check for common problems that cause the log ” Using [{}] data paths; mounts [{}]; net usable_space [{}]; net total_space [{}]; types [{}] ” to appear. To understand the issues related to this log, read the explanation below about the following Elasticsearch concepts: node.

Log Context

Log “Using [{}] data paths; mounts [{}]; net usable_space [{}]; net total_space [{}]; types [{}]” classname is NodeEnvironment.java.
We extracted the following from Elasticsearch source code for those seeking an in-depth context :

totFSPath.add(fsPath);
                }
            }

            // Just log a 1-line summary:
            logger.info("using [{}] data paths; mounts [{}]; net usable_space [{}]; net total_space [{}]; types [{}]";
                nodePaths.length; allMounts; totFSPath.getAvailable(); totFSPath.getTotal(); toString(allTypes));
        }
    }
