The mc tree command lists all prefixes inside an AIStor bucket in a tree format. The command optionally supports listing all objects inside of bucket at each prefix, including the bucket root. You can also use mc tree against a local filesystem directory to produce similar results to the tree command-line tool. Syntax Example The following command prints a complete tree of all objects at any depth in the mydata bucket on the myaistor AIStor deployment:

This page documents settings for configuring an POSTGRES service as a target for Bucket Notifications. See Publish Events to PostgreSQL for a tutorial on using these settings. 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 mc retention info command configures the Write-Once Read-Many (WORM) locking settings for an object or object(s) in a bucket. You can also set the default object lock settings for a bucket, where all objects without explicit object lock settings inherit the bucket default. To lock an object under legal hold, use mc legalhold set. mc retention info requires that the specified bucket has object locking enabled. You can enable object locking at bucket creation. See mc mb --with-lock for documentation on creating buckets with object locking enabled.

The mc support top locks command lists the ten oldest locks on an AIStor deployment. The command outputs the age of the lock, type of lock, owner, and resource. The output resembles the following: Since Type Owner Resource 13 hours ago WRITE 10.68.100.18:9000 .minio.sys/leader.lock 13 hours ago WRITE 10.68.100.18:9000 .minio.sys/callhome/runCallhome.lock 13 hours ago WRITE 10.68.100.23:9000 .minio.sys/new-drive-healing/0/0 Syntax Example The following command displays the current in-progress S3 API calls on the alias myaistor.

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 replicate status command displays the replication status of an AIStor bucket. The status also lists the remote target path or location. Example Syntax The following command displays the current replication status of the mydata bucket on the myaistor AIStor deployment:

The mc tag command adds, removes, and lists tags associated to a bucket or object. AIStor supports adding up to 10 custom tags to an object. Subcommands mc tag includes the following subcommands: Subcommand Description list List all tags from a bucket or object. remove Remove all tags from a bucket or object. set Set one or more tags on a bucket or object.

In rare circumstances, you may need to restore site replication service account information to a peer in the cluster. Seeing AccessDenied for site replication calls either in logs or with :mc-cmd:mc admin trace indicates a need to restore service account information to a peer. This error typically results when the service accounts for site replication of one of the peer sites have been lost or corrupted. Procedure To restore the required information, export the service account information from an existing healthy peer site and import it to the site with the missing account information.

You can enable versioning using one of the following: At bucket creation AIStor Console (WebUI) AIStor Client CLI Developers can also enable versioning on buckets through an S3-compatible SDK Enable versioning at bucket creation AIStor Console When creating a bucket in the Console, select either Versioned as the bucket Type.
