May I know how & where to check if the Aggregate is running out of spaces, to avoid LUN offline because of not enough spaces to expand.
I have an Aggregate 16 TB with 6 TB used spaces as displayed in Web GUI.
However, when I checked its 3 x Volumes (with Dedup and Compression Storage Efficiency) which are all Thin Provisioned (total volume spaces over-provioned to 18 TB), all 3 x Volumes are 90% spaces utilized.
Inside the 3 x Volumes, all the LUN with Space Reservation but NO Snapshot.
This has led me to think that the Aggregate might be running out of disk spaces soon despite the Aggregate is still showing 6TB used spaces only.
How to check if my aggregate isn't running of spaces soon???
