mc support inspect

Table of Contents

SUBNET Registration Required

The mc support commands are designed for MinIO deployments registered with MinIO SUBNET to ensure optimal outcome of diagnostics and performance testing. Deployments not registered with SUBNET cannot use the mc support commands.

Description

The mc support inspect command collects the data and metadata associated to objects at the specified path. MinIO assembles this data from each backend drive storing an erasure shard for each specified object.

The command produces an encrypted zip file that includes all matching files with their respective host+drive+path.

The resulting report is intended for use by MinIO Engineering via MinIO SUBNET and may contain internal or private data points associated to the object. Exercise caution before sending a report to a third party or posting the report in a public forum.

Important

mc support inspect requires a MinIO deployment server from October 2021 or later.

Wildcards

The command suports wildcard * pattern matching for prefixes or objects.

mc support inspect ALIAS/bucket/path/**/xl.meta

This command collects all xl.meta associated to objects at ALIAS/bucket/path/.

Examples

Download Metadata for an Object

You can download the metadata for an object. Metadata stores in an xl.meta binary file.

The following command downloads the xl.meta from mybucket/myobject on the minio1 deployment.

The file downloads from all drives as a zip archive file.

mc support inspect minio1/mybucket/myobject/xl.meta

The contents of the xl.meta file are not human readable. You can convert the contents of an xl.meta file to JSON format.

Download All Objects at a Prefix Recursively

The following command downloads all objects recursively found at a prefix.

Caution

This can be an expensive operation. Proceed with caution.
