The mc support top disk command displays current drive statistics. Syntax Example The following command displays the current disk usage and performance on the alias myminio.

This guide details the JDK Migration process.

Distributed AIStor deployments rely on Erasure Coding to provide built-in tolerance for multiple drive or node failures. Depending on the deployment topology and the selected erasure code parity, AIStor can tolerate the loss of up to half the drives or nodes in the deployment while maintaining read access (“read quorum”) to objects. The following table lists the typical types of failure in an AIStor deployment and links to procedures for recovering from each:

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.

AIStor Server implements Erasure Coding as a core component in providing data redundancy and availability. The diagrams and content in this section present a simplified view of erasure coding operations and are not intended to represent the complexities of the AIStor Server’s full erasure coding implementation. AIStor groups drives in each server pool into one or more Erasure Sets of the same size.

The mc ls command lists buckets and objects on an AIStor deployment. You can also use mc ls to list objects on S3-compatible services. Syntax Example The following command lists all objects in a bucket on the myminio deployment:

Syntax The mc legalhold info command returns the current legal hold setting for an object or objects. mc legalhold requires that the specified bucket has object locking enabled. You can only enable object locking at bucket creation. See mc mb --with-lock for documentation on creating buckets with object locking enabled.

The mc od command copies a local file to a remote location in a specified number of parts and part sizes. The command outputs the time it took to upload the file. Use the mc od to mimic the functionality of the Linux dd command. Example The following command Upload 200MiB of a file to a bucket in 5 parts of size 40MiB. The output shows the results of the upload, including the length of time it took for the upload to complete.
