mc admin update

Description

The mc admin update command updates all AIStor servers in the deployment. The command also supports using a private mirror server for environments where the deployment does not have public internet access.

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.

This command is intended for updating AIStor deployments where all installations use the minio binary installation path and do not rely on systemctl, DEB, or RPM packages.

Syntax

Example

Use mc admin update to update each minio server process in the AIStor deployment:

mc admin update ALIAS

Replace ALIAS with the alias of the AIStor deployment.

After running the command, answer yes to the prompt to confirm and process the update.

Syntax

mc admin update supports the following arguments:

ALIAS

The alias of the AIStor deployment to update.

If the specified ALIAS corresponds to a distributed AIStor deployment, mc admin update updates all AIStor servers in the deployment at the same time.

Use mc alias list to review the configured aliases and their corresponding AIStor deployment endpoints.

MIRROR_URL

The mirror URL of the minio server binary to use for updating AIStor servers in the ALIAS deployment.

--yes

Alias: -y

Optional

Pass this flag to confirm the update and bypass the confirmation prompt.

Behavior

Updates are Non-Disruptive

mc admin update updates the binary and restarts all AIStor servers in the deployment simultaneously. AIStor operations are atomic and strictly consistent and as such the restart process is non-disruptive to applications.

MinIO strongly recommends only performing simultaneous upgrade-and-restart procedures. Do not perform “rolling” (that is, one node at a time) upgrade procedures.

Permissions

The user running the command must have write permissions to the target path where the AIStor Server binary installs.
