Fill protection and growth

DonkeyFleet tracks destination fill episodes, recommends growth, and can grow a destination in auto mode when every guardrail is satisfied.

Capacity language​

  • Provisioned is the logical allocated size and is used for capacity planning.
  • Physical is actual stored data and is used for baseline-transfer estimates.

Operator text and approvals must show both when both matter.

Episode behavior​

A sustained threshold breach opens a fill episode. The recommendation is stable for that episode, which prevents every reconcile from generating a new plan item. Recovery closes the episode.

Automatic growth is destination-only and never shrinks a volume.

Safe configuration​

Set the cap explicitly

The accepted safety design caps autonomous growth at 5 percent. The current policy UI can save a 10 percent default. Configure 5 percent or less until that mismatch is corrected.

Before auto mode:

  • verify aggregate headroom and any platform quota;
  • verify the growth percentage and absolute bounds;
  • test an episode in dry-run;
  • confirm notifications and audit events reach the operating team.

If a grow request remains an unresolved ONTAP job, DonkeyFleet polls the stored job UUID on the next run and does not reissue the request.
