Description

NS8 primary storage works best with drives offering fast random access. However, some data-intensive applications (e.g. Samba, Mail, Nextcloud, backup destinations) require large archive space. To optimize resource usage, specific application volumes can be mounted on separate, large-capacity drives instead of consuming the primary storage.

Proposed solution

  • Developer: Allow module developers to define which volumes can use additional disks.
  • Sysadmin: Enable and manage additional disks on cluster nodes for application use.
  • Sysadmin: During app install, restore, or clone, allow selection of the node’s additional disk to host the app’s volume.

Alternative solution

  • Support additional filesystem mount points, making them available for applications.
  • Allow module developers to define a volume role. Matching between available mount points and volumes can be automatic or user-supervised.
  • Define data migration policy: existing data may be preserved, migrated, or trigger a fatal error, depending on the developer’s decision.

    In Testing Core 3.14.0-dev.3

    Test case

    • Install NS8 with core from Testing
    • Mount one or more additional disks
    • Configure volume assignments in /etc/nethserver/volumes.conf according to https://nethserver.github.io/ns8-core/modules/volumes/ guidelines (direct edit, or by volumectl helper)
    • Check that application volumes are created and data is correctly written to additional disks in the following scenarios:
      • New app installation
      • Restore from backup
      • Clone and Move
