AIStor provides tools for scaling your cluster capacity by adding or removing server pools. These tools allow you to expand storage capacity or retire aging hardware without disrupting ongoing operations. Planning for growth MinIO recommends initially sizing clusters for at least 2-3 years of anticipated data growth. This approach minimizes the frequency of expansion operations and simplifies long-term capacity management.

The procedure on this page creates a new bucket replication rule for two-way “active-active” synchronization of objects between AIStor buckets. Requirements Replication requires all participating clusters meet the bucket replication requirements. This procedure assumes you have reviewed and validated those requirements.

AIStor supports publishing bucket notification events to a NATS service endpoint. Prerequisites The AIStor mc command line tool This procedure uses the mc command line tool for certain actions. See the mc Quickstart for installation instructions. Add a NATS endpoint to an AIStor Server The following procedure adds a new NATS service endpoint for supporting bucket notifications in an AIStor Server.

You can use the AIStor Console to perform several of the identity and access management functions available in AIStor, such as: Create and manage user credentials or groups with the built-in AIStor IDP, connect to one or more OIDC providers, or add an LDAP provider for Single Sign On. Configure single sign on workflows using either OpenID Connect or AD/LDAP. View, manage, and create access policies. Create child access keys that inherit the parent’s permissions. IAM Users The IAM Users section provides a management interface for AIStor-managed users.

AIStor provides multiple replication strategies to ensure data availability, support disaster recovery, enable geographic distribution, and facilitate data migration between clusters. Each replication method serves different use cases and operates at different levels, from entire cluster to individual objects. Replication methods AIStor supports four distinct replication and synchronization approaches:

This page summarizes how a DELETE operation affects objects depending on the configuration of the bucket that contains the object. Any combination of the following factors may impact how DELETE operations function: Bucket versioning Object locking rules Object Lifecycle Management rules Object tiering Site or bucket replication Scanner Permissions AIStor uses a policy based access control system for access management. The user or service account must provide the correct policy action and conditions to allow a DELETE for the bucket and object.

The mc admin cluster bucket export command exports bucket metadata for use with the (mc admin cluster bucket import) command. You can use this command to manually back up the metadata for the specified AIStor bucket. The command always saves the output as cluster-metadata.zip. If you specify only the deployment as the target, this command backs up all bucket metadata on the target deployment.

This section documents best practices and tutorials for updating the AIStor server on Linux and Kubernetes infrastructure to a newer release. All AIStor software supports non-disruptive upgrades with zero downtime. In optimal environments, cluster-wide upgrades typically complete in under 500 milliseconds with large clusters (1000+ nodes) completing in less than 5 seconds. Applications using MinIO or S3 SDKs can rely on the built-in transparent retry to ensure continuous operations during the update procedure.

Description The mc admin trace command displays API operations occurring on the target AIStor deployment. Example Example Use mc admin trace to monitor API operations on an AIStor deployment:

Description The mc admin cluster bucket command and its subcommands provide tools for manually importing and exporting AIStor bucket metadata. This metadata includes configurations related to features like lifecycle management rules. You can use this metadata as a snapshot of the bucket configuration for restoration later, such as part of or backup/restore operations.
