node_disk_update Update node disks ~145
Update the disk configuration for a node. `disks` is the raw array of Longhorn Disk objects (path, allowScheduling, storageReserved, tags, diskType, ...) — inspect the node via node_get first to see the current shape. Disabling scheduling or shrinking storageReserved on a disk can strand replicas. Destructive. Do not call this unless the user has explicitly authorized it in this conversation — never proactively, speculatively, or as a side effect of another task.

Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
node_update Update node ~156
Update a Longhorn node record (e.g. allowScheduling, evictionRequested, tags). Fields you omit are left unchanged (read-merge-write under the hood — the API itself does a full replace on PUT). `evictionRequested: true` drains all replicas/backing images off the node. Destructive. Do not call this unless the user has explicitly authorized it in this conversation — never proactively, speculatively, or as a side effect of another task. Longhorn docs: https://longhorn.io/docs/1.12.1/nodes-and-volumes/nodes/
