Adding storage volumes to Storage Nodes

You can expand the storage capacity of non-appliance Storage Nodes that have fewer than 16 storage volumes by adding additional storage volumes. You might need to add storage volumes to more than one Storage Node to satisfy ILM requirements for replicated or erasure-coded copies.

About this task

The underlying storage of a Storage Node is divided into a fixed number of storage volumes. Storage volumes are block-based storage devices that are formatted by the StorageGRID system and mounted to store objects. Each Storage Node can support up to 16 storage volumes, which are called object stores in the Grid Manager.

Note: Object metadata is always stored to object store 0.

Each object store corresponds to a mount point on the same Storage Node. That is, the object store with an ID of 0000 corresponds to the /var/local/rangedb/0 mount point.

Before adding new storage volumes, use the Grid Manager to view the current object stores for each Storage Node as well as the corresponding mount points. You can use this information when adding storage volumes.

Steps

  1. Select Nodes > site > Storage Node > Storage.
  2. Scroll down to view the amounts of available storage for each volume and object store.

    The Worldwide Name for each disk matches the volume world-wide identifier (WWID) that appears when you view standard volume properties in SANtricity software (the management software connected to the appliance's storage controller).

    To help you interpret disk read and write statistics related to volume mount points, the first portion of the name shown in the Name column of the Disk Devices table (that is, sdc, sdd, sde, and so on) matches the value shown in the Device column of the Volumes table.
