Nodes

• kata_thinpool — the kata-firecracker-devmapper LVM thin-pool (lvs: size, data%, metadata%).
• k7d_disks — the k7d disk pool, an XFS loopback mount at /var/lib/k7d/disks (df: size, used, available).

Behavior

• Pools that don’t exist on a node (e.g. a kql-only node with no thin-pool) produce an error detail for that field.
• A node whose k7-agent pod is unreachable gets a loud {"error": ...} entry — nodes are never silently omitted.
• The same data is available via k7 nodes storage (--json for the raw payload) and Client.nodes_storage() in the Python SDK.
