Required release version This command is available in AIStor Client RELEASE.2025-03-31T22-38-30Z or later. The functionality requires AIStor RELEASE.2025-03-27T23-09-45Z or later. The mc admin accesskey sts-revoke command removes security token service (sts) credentials associated with an account. Revoke all STS tokens for an account, or specify the type(s) of STS tokens to revoke for an account.

Description The mc admin config command manages configuration settings for the AIStor Server. Examples Syntax mc admin config set Sets a configuration key on the AIStor deployment. Configurations defined by environment variables override configurations defined by this command.

The mc admin accesskey edit command modifies the configuration of an access key associated to the specified user. The command requires that at least one attribute of the access key change. Otherwise, the command exits with an error message. Syntax Example The following command applies a new policy and secret key to the myuserserviceaccount access key on the myaistor deployment:

The following procedure adds a server pool to an existing AIStor cluster running on bare-metal infrastructure. Each pool expands the total available storage capacity of the cluster while maintaining the overall availability of the cluster. A new pool is a set of new nodes and drives that meet the cluster’s erasure set requirements and parity levels. You can use MinIO’s Erasure Code Calculator to check the Erasure Code Stripe Size (K+M) of your new pool to confirm that it meets the EC:M value of current cluster. MinIO strongly recommends seeking an architecture review from MinIO Engineering through SUBNET to analyze potential performance impacts before committing to a new pool for your cluster.

This page documents upgrade procedures for AIStor Server deployments on bare-metal Linux infrastructure. 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. Upgrade AIStor using DEB or RPM Use these steps to upgrade an AIStor deployment where the server process is managed by systemctl, such as those created using the AIStor DEB/RPM packages.

The following procedures decommissions one or more pools on a Linux bare-metal deployment. Review the AIStor deployment topology The mc admin decommission command returns a list of all pools in the AIStor deployment: mc admin decommission status myaistor The command returns output similar to the following: ┌─────┬──────────────────────────────────────────────────────────────────┬──────────────────────────────────┬────────┐ │ ID │ Pools │ Capacity │ Status │ │ 1st │ https://aistor-{01...04}.example.com:9000/mnt/disk{1...4}/aistor │ 10 TiB (used) / 10 TiB (total) │ Active │ │ 2nd │ https://aistor-{05...08}.example.com:9000/mnt/disk{1...4}/aistor │ 60 TiB (used) / 100 TiB (total) │ Active │ │ 3rd │ https://aistor-{09...12}.example.com:9000/mnt/disk{1...4}/aistor │ 40 TiB (used) / 100 TiB (total) │ Active │ └─────┴──────────────────────────────────────────────────────────────────┴──────────────────────────────────┴────────┘ The example deployment above has three pools. Each pool has four servers with four drives each.

The mc admin kms key command performs cryptographic key management operations through the AIStor Key Encryption Service (KES). Syntax mc admin kms key create Creates a new master key on a Key Management System (KMS).

The mc admin cluster bucket import command imports bucket metadata as created by the mc admin cluster bucket export command. You can use this command to manually restore the metadata to the specified bucket on an AIStor deployment. If you specify only the deployment as the target, this command applies the metadata objects to all matching buckets on the target. Syntax Example The following command imports bucket metadata for the myaistor deployment from a file:

Prints Prometheus metrics for a cluster. The output includes additional information about each metric, such as if its value is a counter or gauge. Syntax Example The following command prints v3 Prometheus metrics for the deployment at alias myaistor:

The mc admin user add command adds a new AIStor user to the target AIStor deployment. To manage external Identity Provider users, see OIDC or AD/LDAP. Syntax Example The following command creates a new user newuser on the myaistor AIStor deployment:
