The SCALE Storage section has controls for pool, snapshot, and disk management. The storage section also has options for datasets, zvols, and permissions.

For guidance on clustering storage across multiple SCALE systems, see (Clustering and Sharing SCALE Volumes with TrueCommand)[/solutions/integrations/smbclustering/].

Storage Overview

StorageSCALE

The top row of the SCALE storage screen lets users search for existing pools, datasets, and zvols.

The Import button lets users reconnect pools exported/disconnected from the current system or created on another system. The import button also reconnects pools after users reinstall or upgrade the TrueNAS system.

The Create Pool button creates ZFS data storage “pools” with physical disks to efficiently store and protect data.

The Snapshots drop-down creates snapshots, which provide read-only point-in-time copies of a file system, volume, or a running virtual machine.

The Disks drop-down lets users manage, wipe, and import storage disks that TrueNAS will use for ZFS data storage.

The Storage screen displays the pools, datasets, and zvols users have created on the system. Users may perform actions to root pools or specific datasets using the Pool Actions and Dataset Actions menus.

Storage Article Summaries

  • Pools
  • TrueNAS uses ZFS data storage pools to efficiently store and protect data. What is a pool? expand Storage pools are attached drives organized into virtual devices (vdevs). ZFS and TrueNAS periodically review and heal when discovering a bad block in a pool. Drives are arranged inside vdevs to provide varying amounts of redundancy and performance. Combined, ZFS and vdevs combined create high-performance pools, pools that maximize data lifetime, and all situations in between.

    • Fusion Pools
    • Fusion Pools are also known as ZFS allocation classes, ZFS special vdevs, and metadata vdevs (Metadata vdev type on the Pool Manager screen.). What's a special vdev? expand A special vdev can store meta data such as file locations and allocation tables. The allocations in the special class are dedicated to specific block types. By default, this includes all metadata, the indirect blocks of user data, and any deduplication tables.
