Managing Object Stores

This page describes how to view and manage object stores using the GUI and the CLI.

Overview

As described in the Object Stores Overview page, Weka utilizes object stores for either tiering or backup when attaching object-store buckets to a filesystem.

Since object-store buckets may reside in different physical object stores, for better QoS between them, Weka requires the mapping between the bucket to the physical object-store.

Object-store in Weka generally represents a physical entity (on-premises or in the cloud), grouping several object-store buckets. An object-store or object-store bucket can be either local (used for tiering+snapshots) or remote (used for snapshots only). An object-store bucket must be added to an object-store with the same type.

This grouping under a physical object-store allows:

• Better QoS when more than one physical object-store is involved

• Restrictions on downloading from a remote object-store

  • By default, very low bandwidth is configured for downloading from a remote bucket since this may incur extra charges for on-premises systems where the remote bucket is in the cloud.

• Ease-of adding new buckets

  • It is possible to configure the connection parameters on the object-store level and, if not specified differently, automatically use them for added buckets.

Note: Initially, the system comes up with two pre-configured object-stores, one for groupinglocal buckets for tiering and snapshots (nameddefault) and one for grouping remote buckets for snapshots-only (named remote_default).

Note: Currently, only one local and one remote object-store are supported in general operation. It is only transiently supported to have more than one local object-store when there is a need to recover from a remote snapshot (this recovery might inccur significant charges when working with a cloud backup). If there is no other way (snapshot is not present locally) it is possible to use this procedure to recover from a remote snapshot.

Support for more than one local/remote object-stores will be rolled out in a future version.

Viewing Object-Stores

Viewing Object-Stores Using the CLI

Command: weka fs tier obs

This command is used to view information on all the object stores configured to the Weka system.

Note: Using the GUI only object-store buckets are present. Adding an object-store bucket will add it to the only local or remote object-store present. If more than one is present (such as during the time recovering from a remote snapshot), the CLI should be used.

Editing Object-Stores

Editing an Object-Store Using the CLI

Command: weka fs tier obs update

Use the following command line to edit an object store:

weka fs tier obs update <name> [--new-name new-name] [--site site] [--hostname=<hostname>] [--port=<port>] [--auth-method=<auth-method>] [--region=<region>] [--access-key-id=<access-key-id>] [--secret-key=<secret-key>] [--protocol=<protocol>] [--bandwidth=<bandwidth>] [--download-bandwidth=<download-bandwidth>] [--upload-bandwidth=<upload-bandwidth>] [--max-concurrent-downloads=<max-concurrent-downloads>] [--max-concurrent-uploads=<max-concurrent-uploads>] [--max-concurrent-removals=<max-concurrent-removals>] [--enable-upload-tags=<enable-upload-tags>]

Viewing Object-Store Buckets

Viewing Object-Store Buckets Using the GUI

The main object store screen in the GUI lists all existing object-store buckets and can also display information about a specific object-store bucket, including the bucket name, status and region.

Main Object Store View Screen

Viewing Object-Store Buckets Using the CLI

Command: weka fs tier s3

This command is used to view information on all the object-store buckets configured to the Weka system.

Adding an Object-Store Bucket

Adding an Object-Store Bucket Using the GUI

From the main object store view screen, click the "+" button at the top left-hand side of the screen. The Configure Object Store dialog box will be displayed.
