Lists all policies on the target AIStor deployment. Syntax Example The following command lists all policies on the deployment at alias myaistor.

Description mc admin object info displays a summary of part and shard information about a specified object. The output includes information for each part or shard of the object, including: Part number Pool number Node Erasure set Drive Filename Size By default, the output uses a set of gridded blocks to indicate the parts of object. Colors indicate the status of the specific part.

The mc admin info command displays information on an AIStor server. For distributed AIStor deployments, mc admin info displays information for each node in the deployment. The output of the command resembles the following for a four-node cluster: ● node1.example.com:9000 Uptime: 3 days Version: 2025-01-01T00-00-00Z Network: 4/4 OK Drives: 4/4 OK Pool: 1 ● node2.example.com:9000 Uptime: 3 days Version: 2025-01-01T00-00-00Z Network: 4/4 OK Drives: 4/4 OK Pool: 1 ● node3.example.com:9000 Uptime: 3 days Version: 2025-01-01T00-00-00Z Network: 4/4 OK Drives: 4/4 OK Pool: 1 ● node4.example.com:9000 Uptime: 3 days Version: 2025-01-01T00-00-00Z Network: 4/4 OK Drives: 4/4 OK Pool: 1 Pools: 1st, Erasure sets: 1, Drives per erasure set: 16 1.5 TiB Used, 12 Buckets, 48000 Objects 16 drives online, 0 drives offline, EC:4 Syntax Example The following command displays AIStor server information for the alias myaistor:

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.

Removes an IAM policy from the target AIStor deployment. Syntax Example The following command removes the policy readonly from the deployment at alias myaistor.

The mc batch describe command outputs the job definition for a specified job ID. You must specify the job ID. To find the job ID, use mc batch list. Syntax Example The following command outputs the job definition for the job identified as KwSysDpxcBU9FNhGkn2dCf.

Description The mc admin update command updates all AIStor servers in the deployment. After running the command, a prompt displays to confirm the update. Type y and [ENTER] to confirm and proceed with the update. The user must have write permissions for the target location where the binary installs.

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 replicate command creates and manages site replication for a set of AIStor peer sites. Site replication mimics an active-active bucket replication, but for multiple AIStor deployments. Wherever a change occurs to IAM settings, buckets, or objects across the set of sites, the change replicates across all sites in the site replication group.

Description The mc admin service command can restart or unfreeze AIStor servers. mc admin service affects all AIStor servers in the target deployment at the same time. The command interrupts in-progress API operations on the AIStor deployment. Use caution when issuing this command to a deployment.
