Use mc admin maintenance hosts to create lists of maintenance groups. The command generates lists of hosts that do not share erasure sets. Hosts that do not share a erasure sets can go into maintenance at the same time without causing service disruptions. Syntax The mc admin maintenance hosts command DESCRIPTION

Description The mc admin accesskey command and its subcommands create and manage Access Keys for internally managed users on an AIStor deployment. Each access key is linked to a user identity and inherits the policies attached to its parent user or those groups in which the parent user has membership. Each access key also supports an optional inline policy which further restricts access to a subset of actions and resources available to the parent user.

AIStor Helm installations consist of two primary parts: The operator chart that controls resources like CustomResourceDefinitions The object-store chart that deploys the AIStor Object Store You can also upgrade only the AIStor Object Store image used by a given chart. This page documents a procedure for all three upgrade paths. 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.

The mc anonymous set command sets anonymous (that is, unauthenticated or public) access policies for a bucket. Buckets with anonymous policies allow clients to access the bucket contents and perform actions consistent with the specified policy without authentication. To set anonymous bucket policies using an IAM JSON policy, use the mc anonymous set-json command. Syntax Example The following command sets the anonymous access policy for the mydata bucket on the myaistor AIStor deployment:

Generates a metrics scraping configuration file for use with Prometheus. Syntax Example The following command generates a v3 Prometheus scraping configuration file for the deployment at alias myaistor:

The mc admin scanner status command displays a real-time summary of scanner information for an AIStor Server. This command has an alias of mc admin scanner info. Syntax Example The following example returns information about the current state of the scanner process.

Description The mc anonymous command supports setting or removing anonymous policies to a bucket and its contents. Buckets with anonymous policies allow public access where clients can perform any action granted by the policy without authentication. Subcommands mc anonymous includes the following subcommands:

The mc admin cluster iam import command imports IAM metadata as created by the mc admin cluster iam export command. You can use this command to manually restore IAM metadata settings for an AIStor deployment. The command outputs the results of the import, including the following: count of individual entities imported by entity type list of policies imported by entity type they imported to list of entities that failed to import Syntax Example The following command imports the IAM metadata of the specified file onto the myaistor deployment.

Lists the entities associated with a policy, user, or group on a target AIStor deployment. This command only returns minio-managed users and groups. To list entities associated with an Active Directory or LDAP (AD/LDAP) configuration, use mc idp ldap policy entities.

Syntax Example The following command retrieves the JSON-formatted anonymous policy for the mydata bucket on the myaistor AIStor deployment: mc anonymous get-json myaistor/mydata Syntax The command has the following syntax:
