non-conformant dataset

Hi!

When an aggregate on the nearstore (secondary filer, snapvault destination) reaches its full threshold the dataset becomes non-conformant.

This makes snapcreator to fail.

Why cant snapcreator update the dataset with snaphot information because of this.

I agree a warning might be in its place but to fail?

PM itself can take local snashots an update the dataset, so why cant snapcreator?

Regards Magnus

There are two stages in the snapcreator process

1) backup version create --> this creates a new backup (snapshot) and tells the dataset

2) pmbackupupdate --> this requests the dataset to update, with whatever the protection policy.

From you logs, are you seeing the 1st step to happen?

Please share your logs if you can.

You may email me to sivar at netapp.com

As you can see from this logs it just detects that dataset is non-conformant and exits.

The only reason for it to be non-conformant is because the destination snapvault aggregate has reached it full threshold. (90%)

This should not be a reason for not registering the primary snapshot in my opinion.

Snap Creator just checks if dataset is conformant if it isnt SC exits.

Protection Manager determines if a dataset is conforment or not so you need to look at why Protection Manager is flagging dataset as non-conformant under this condition.
