Snapshot reserve 0 pourcent but space used

Hi,

I have noticed that i have volume with a snapshot reserve of 0 pourcent but some space is still used by snapshot ?

How is that possible ?

Best regards,

What is the output for this command for the 'subject' volume?

volume show -volume <volume> -fields snapshot-space-used,snapshot-reserve-available,snapshot-count

Could the snapshot used-space you have observed - is basically 'snapshots' in the active-file system space.

That's exactly what I meant when I said - Could the snapshot used-space you have observed - is basically 'snapshots' in the active-file system space.

Basically:

If snapshot reserve is set to : 0, snapshots will consume active-file system space., these snapshots in the image takes up the volume space. If you do NOT want any snapshots then you must disable the snapshots.
