ResourceHandler
Defined in:
lib/pvectl/commands/get/handlers/disks.rb

Overview

Handler for listing physical disks on Proxmox nodes.

Implements ResourceHandler interface for the “disks” resource type. Uses Repositories::Disk for data access and Presenters::Disk for formatting.

Examples:

Using via ResourceRegistry

handler = ResourceRegistry.for("disks")
disks = handler.list(node: "pve1")

Constructor Details

#initialize(repository: nil) ⇒ Disks

Creates handler with optional repository for dependency injection.

Parameters:

  • repository (Repositories::Disk, nil) (defaults to: nil) —

    repository (default: create new)

Instance Method Details

#describe(name:, node: nil, args: [], vmid: nil) ⇒ Models::PhysicalDisk

Describes a single physical disk with SMART data.

Locates the disk by devpath across all nodes (or a specific node), then fetches SMART data and merges it into the model.

Parameters:

  • name (String) —

    device path (e.g., “/dev/nvme0n1”)

  • node (String, nil) (defaults to: nil) —

    optional node filter

  • args (Array<String>) (defaults to: []) —

    unused, for interface compatibility

  • vmid (String, nil) (defaults to: nil) —

    unused, for interface compatibility

Returns:

end

#list(node: nil, name: nil, args: [], storage: nil, **_options) ⇒ Array<Models::PhysicalDisk>

Lists physical disks with optional filtering.

Parameters:

  • node (String, nil) (defaults to: nil) —

    filter by node name

  • name (String, nil) (defaults to: nil) —

    filter by device path (e.g., “/dev/sda”)

  • args (Array<String>) (defaults to: []) —

    unused, for interface compatibility

  • storage (String, nil) (defaults to: nil) —

    unused, for interface compatibility
