AIStor supports running in S3 Express Mode. This mode enables directory bucket behavior for optimized heirarchial storage structures. While object store prefixes generally support organized storage, S3 Express Mode implements the specific directory bucket behaviors documented by AWS. S3Express mode disables most API operations outside of simple bucket and object PUT, GET, DELETE, and LIST operations. All other API operations return not supported errors, including operations for versioning, locking, and replication.

The mc undo command reverses changes due to either a PUT or DELETE operation at a specified path. Syntax Example The following command reverts the last three uploads and/or deletions of the file.zip object on the myminio deployment in the data bucket:

The mc ilm tier ls command shows the remote tiers configured on a deployment. The mc ilm tier list command has equivalent functionality to mc ilm tier ls. Syntax Example The following example outputs a list of the existing remote tiers on the myminio deployment.

mc support telemetry generates OpenTelemetry-formatted trace information to either live-stream or record-then-transmit to an OpenTelemetry Protocol (OTLP)-compatible service. The command collects trace data across all nodes in the AIStor deployment. The information can be relayed to a specified collector, recorded to a local encrypted or unencrypted file, or replayed from a local file to a collector. These commands are designed to capture traces in support of ongoing troubleshooting and diagnostics with MinIO Engineering.

The following section documents environment variables for configuring AIStor to publish audit logs to an HTTP webhook endpoint. See Publish Audit Logs to HTTP Webhook for more complete documentation and tutorials on using these environment variables. Example Environment Variables You can specify multiple webhook endpoints as audit log targets by appending a unique identifier _ID for each set of related logging settings.

Syntax The mc share ls command displays any unexpired presigned URLs generated by mc share upload or mc share download The mc share list command has equivalent functionality to mc share ls. Applications can perform a PUT to retrieve the object from the URL.

The AIStor Security Token Service (STS) APIs allow applications to generate temporary credentials for accessing the AIStor Server. The STS API is required for AIStor Servers configured to use external identity managers, as the API allows conversion of the external IDP credentials into AWS Signature v4-compatible credentials. STS API endpoints AIStor supports the following STS API endpoints:

This page covers settings that control root (superuser) access for the AIStor process. The root user has complete access and permissions to perform operations on the AIStor deployment. Root User and Root Password are required even if you use the MinIO Key Encryption Service or other key management utility. You can establish or modify settings by defining: an environment variable on the host system prior to starting or restarting the AIStor Server. Refer to your operating system’s documentation for how to define an environment variable. a configuration setting using mc admin config set. If you define both an environment variable and the similar configuration setting, AIStor uses the environment variable value.

The following section documents settings for configuring AIStor to publish minio server logs to an HTTP webhook endpoint. See Publish Server Logs to HTTP Webhook for more complete documentation and tutorials on using these settings. Example Environment Variables You can specify multiple webhook endpoints as log targets by appending a unique identifier _ID for each set of related logging environment variables. For example, the following settings define two distinct server log webhook endpoints:
