Upgrade MinIO Community Edition clusters on Linux to AIStor by replacing binaries, adding license files, and restarting the cluster.

AIStor can make the loss of an entire site, while significant, a relatively minor incident. Site recovery depends on the replication option you use for the site. Replication type Restoration method Site Replication Total restoration of IAM configurations, bucket configurations, and data from the healthy peer site(s) Bucket Replication Data restoration of objects and metadata from a healthy remote location for each bucket configured for replication mc mirror Data restoration of objects only from a healthy remote location with no versioning Site replication healing automatically adds IAM settings, buckets, bucket configurations, and objects from the existing site(s) to the new site with no further action required.

Each AIStor server process exposes unauthenticated endpoints for probing server uptime and deployment high availability for simple healthchecks. These endpoints return an HTTP status code indicating whether the underlying resource is healthy or satisfies read/write quorum. The server exposes no other data through these endpoints. AIStor liveness Use the following endpoint to test if the specified AIStor server is up and ready to serve requests:

Description The mc admin prometheus command and its subcommands provide access to MinIO Prometheus metrics. Subcommands Subcommand Description generate The mc admin prometheus generate command generates a metrics scraping configuration file for use with Prometheus. metrics The mc admin prometheus metrics command prints Prometheus metrics for a cluster.

The mc admin cluster bucket export command exports bucket metadata for use with the (mc admin cluster bucket import) command. You can use this command to manually back up the metadata for the specified AIStor bucket. The command always saves the output as cluster-metadata.zip. If you specify only the deployment as the target, this command backs up all bucket metadata on the target deployment.

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