NetApp ONTAP volume full

When a NetApp ONTAP volume fills up, deleting snapshots frees space fast, and the wrong one can break the replication your disaster recovery depends on. 2501 works out where the space really went and fixes it within your limits, without deleting data or breaking replication.

Even a volume set to grow on its own can fill when the aggregate beneath it runs short.

What 2501 does

The NetApp ONTAP specialty takes the alert from your ticketing system, confirms the cluster and its nodes are healthy, and works out where the space went and how much room the aggregate has. Where you allow it, it grows the volume while leaving the aggregate enough headroom. It prefers letting the snapshot policy expire old snapshots to deleting them by hand, and deletes one only under real space pressure.

Every change is reported with the state before and after. What it will not do alone comes back as findings with a recommended next step.

You stay in control

• You choose the level: investigate only, act after a person confirms, or act on its own within your rules. The level is set per specialty, not per ticket.
• Replication is protected: it never deletes a snapshot that replication depends on, never switches off a snapshot policy to free space, and never breaks replication without explicit approval.
• No volume is shrunk or destroyed: growing is the only size change it makes.
• Your change process applies: a volume goes offline only with a change ticket, and resynchronising replication or adding a snapshot policy needs confirmation.

Frequently asked

Why is the volume full when its files have not grown? Snapshots and overhead use space too, and each needs a different fix from user data, so 2501 separates them first.

Why not just grow the volume? Where you allow it, it does, if the aggregate has room. A nearly full aggregate hurts performance, so otherwise it reports the numbers.

Does it work with Amazon FSx for NetApp ONTAP? Yes, as well as ONTAP clusters in your own data centre.
