Table of Contents

mc admin heal

Description

The mc admin heal command scans for objects that are damaged or corrupted and heals those objects.

mc admin heal is resource intensive and typically not required even after drive failures or corruption events. Instead, MinIO automatically heals objects damaged by silent bit rot corruption, drive failure, or other issues on POST/GET. MinIO also performs periodic background object healing.

Use mc admin on MinIO Deployments Only

Syntax

mc admin heal has the following syntax:

mc admin heal [FLAGS] TARGET

mc admin heal supports the following arguments:

TARGET

Required

The full path to the bucket or bucket prefix on which the command should perform object healing. Specify the alias <mc alias> of a configured MinIO deployment as the prefix for the path. For example:

mc admin heal play/mybucket/myprefix

If the TARGET bucket or bucket prefix has an active healing scan, the command returns the status of that scan.

--scan

The type of scan to perform. Specify one of the following supported scan modes:

  • normal (default)
  • deep

--recursive, r

Recursively scans for objects in the specified bucket or bucket prefix.

--dry-run

Inspects the ~mc admin heal TARGET bucket or bucket prefix, but does not perform any object healing.

--force-start, f

Force starts the healing process.

--force-stop, s

Force stops the healing sequence.

--remove

Removes dangling objects and data directories in the healing process not referenced by the metadata on a per-drive basis.
