You changed a software image in BCM. How do nodes get the change?
Why B is the answer
Update or reprovision them
Nodes must sync with the image.
In detail
- Nodes must sync with the image, or be reprovisioned.
- Editing the image alone changes nothing on nodes.
Use case
An illustrative scenario, not a real incident.
An image is changed, and nodes are updated, so they pick up the change.
See it in different ways
flowchart LR A["Install head node"] --> B["Software images"] B --> C["Provision nodes"] C --> D["Set up Slurm or Kubernetes"] D --> E["Run workloads"]
sequenceDiagram participant H as Head node participant I as Software image participant C as Category participant N as Compute nodes H->>I: Holds the OS image I->>C: Assigned to a category C->>N: Nodes boot and provision H->>N: Updates when the image changes
flowchart LR S0["Change image"] --> S1["Update or reprovision"] --> S2["Verify"]
Key point: Nodes must sync with the image.
Why the other options are wrong
- A. Clear the Docker build cache
- Docker is unrelated.
- C. Restart the user's browser
- A browser has no effect.
- D. Wait for a Slurm job to finish
- Jobs do not sync images.
