Restrict snapshot space on a volume

Hi,

I want to restrict space for snapshot on a volume to certain percentage. As I have seen in default, if a volume is of 100GB with 20% snapshot definition.

If user has used 60 GB of space and data changes in this drive very quickly, the snaphot size will be large and then it takes space more than allocated 20%. Thus if data is deleted to create space in volume, it does not become available as free space. Is there a way to restrict it to certain size and it should remove old snapshot if new has to be created as in First In First Out.

Thanks,

Yasir Irfat

It is not possible to restrict space (meaning – prevent snapshot creation if it would exceed allocated space). It is possible to configure NetApp to autodelete snapshots in this case. See “snap autodelete” command.
