Recover after Hardware Failure on SILO

Drive Failure Recovery

Mon, 01 Jan 0001 00:00:00 +0000

MinIO supports hot-swapping failed drives with new healthy drives. MinIO detects and heals those drives without requiring any node or deployment-level restart. MinIO healing occurs only on the replaced drive(s) and in most cases has minimal or negligible impact on deployment performance.

MinIO healing ensures consistency and correctness of all data restored onto the drive.

Exclusive access to drives

MinIO requires exclusive access to the drives or volumes provided for object storage. No other processes, software, scripts, or persons should perform any actions directly on the drives or volumes provided to MinIO or the objects or files MinIO places on them.

Node Failure Recovery

If a MinIO node suffers complete hardware failure (e.g. loss of all drives, data, etc.), the node begins healing operations once it rejoins the deployment. MinIO healing occurs only on the replaced hardware and does not typically impact deployment performance.

MinIO healing ensures consistency and correctness of all data restored onto the drive.

Site Failure Recovery

Mon, 01 Jan 0001 00:00:00 +0000

MinIO can make the loss of an entire site, while significant, a relatively minor incident. Site recovery depends on the replication option you use for the site.

Site Replication	Total restoration of IAM configurations, bucket configurations, and data from the healthy peer site(s)
Bucket Replication	Data restoration of objects and metadata from a healthy remote location for each bucket configured for replication
`mc mirror`	Data restoration of objects only from a healthy remote location with no versioning
