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
MinIO does not support using mc admin
commands with other
S3-compatible services, regardless of their claimed compatibility with MinIO
deployments.
