What to do when the snapshot reserve is full on the aggregate

TOBIAS1979 — Thu, 05 Jun 2025 06:16:58 GMT

How should I deal with the fact that the snapshot reserve is full on an aggregate. Our DataOntap version is now updated to 8.02P5 and has been so for about 6 months.
We do not run cluster mode

What are the advantages and disadvantages of removing the snapshot schema?
What can I recover from an aggregate snapshot?

Error mail that I recive

A Warning event at 19 Oct 15:36 W. Europe Daylight Time on Aggregate aggr1 on Active/Active Controller faspri02.intern.hoglandet.se:

The snapshot is 94.00% full (using 1023 GB of 1.06 TB).

I typically turn off aggregate snapshots as I find them not useful. I turn off the snapshot schedules, remove all aggr snapshots and regain the space they consume.

To answer your question, the only thing you can do with an aggregate snapshot that I'm aware of is restore ALL volumes at one time to the snapshot. I'm willing to bet in most environments that's not very useful.

Others may have differing opinions, but my exception to this is aggr0. I leave that one alone and let it operate on the default settings.

Everything bsti@plex.com is dead on.

You need to keep at least 10% free on each aggr.

What are snapshots schedules / reserves for the volumes in this aggregate?

And for the love of pete upgrade to 8.1.1
