I believe the latest term is snapshot overflow.
My question is if snapshots are just going to overflow into the data volume, what's the point of increasing the snapshot reserve? Is it simply to alert you? We have NFS with default snapshot policies so they recycle every two weeks or something (no autodelete) but it's spilling over 40GB into the data volume. So I can increase it from 5 to 6% to rid ourselves of the alerts but my question is, what's the point of a reserve if it's not going to reserve anything and just spill over? Perhaps this is just an NFS thing or specific settings I missed?
Thanks again
