The mc alias export command exports an alias configuration from the existing configuration. The command outputs the result to STDOUT where you can either capture the output as a file or perform further modifications to the output as necessary. Syntax Example The following command exports an alias configuration from the existing host and outputs it to a file:

The mc share upload command generates a temporary presigned URL with integrated access credentials for uploading objects to an AIStor bucket. The temporary URL expires after a configurable time limit. Applications can perform a PUT to upload an object using the URL. For more information on shareable object URLs, see the Amazon S3 documentation on Pre-Signed URLs. Syntax Example The following command generates a new presigned upload URL for the mydata bucket on the myaistor AIStor deployment:

The mc legalhold clear command removes the current legal hold setting for an object or objects. Syntax Removing the legal hold on object(s) does not remove any other GOVERNANCE Mode and COMPLIANCE Mode retention settings in place for the object(s) Example The following command removes the legal hold on all objects in the mydata bucket on the myaistor server.

AIStor supports publishing bucket notification events to MQTT server/broker endpoint. Prerequisites MQTT 3.1 or 3.1.1 Server/Broker This procedure assumes an existing MQTT 3.1 or 3.1.1 server/broker to which the AIStor Server has connectivity. See the mqtt.org software listing for a list of MQTT-compatible server/brokers.

AIStor supports deploying resources onto Windows hosts for local development and evaluation. For the purposes of evaluation or local development, MinIO recommends using a machine released in the last 4 years with at least 8 GB of RAM. You can use any supported version of Windows. For testing or local development using a virtualized environment, including Windows Subsystem for Linux (WSL), use a machine with a higher number of cores and 16 or 32GB of RAM.

Description The mc admin policy commands manage policies for use with MinIO Policy-Based Access Control (PBAC). MinIO PBAC uses IAM-compatible policy JSON documents to define rules for accessing resources on an AIStor server. For complete documentation on MinIO PBAC, including policy document JSON structure and syntax, see Access Management. To manage policies for deployments that use LDAP authentication, see mc idp ldap policy.

Description The mc admin group command manages groups on an AIStor deployment. A group is a collection of users. Each group can have one or more assigned policies that explicitly list the actions and resources to which group members are allowed or denied access. Groups provide a simplified method for managing shared permissions among users with common access patterns and workloads.

You can exclude up to 10 prefixes on a bucket with versioning enabled. This is especially useful for Spark or Hadoop workloads or any process that initially creates objects with temporary prefixes. Prefixes A prefix is a common leading string of characters under a bucket that a set of objects share.

The following procedures decommissions one or more pools on a Linux baremetal 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.

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.
