Overview

Selector for filtering physical disks.

Extends Base with disk-specific field extraction. Supports: type, health, used, node, gpt, mounted.

Examples:

Filter SSDs only

selector = Disk.parse("type=ssd")
ssds = selector.apply(all_disks)

Filter healthy disks on a specific node

selector = Disk.parse("health=PASSED,node=pve1")
filtered = selector.apply(all_disks)
