lun snapshot not possible

[TDUBB1234]

on one of the luns I am getting a lun snapshot not possible.

100GB       85GB       14GB      85%

is it because I dont have enought space?

[andrc]

If a LUN has Space Reservation enabled and Fractional Reserve in the containing volume is set to 100% then the volume must have at least the size of the LUN available as free space or snapshot creation will fail.

I suggest you have a read through the info on Space Management here: https://now.netapp.com/NOW/knowledge/docs/ontap/rel736/html/ontap/semg/GUID-B6A4F6E6-5727-4A3D-A0CC-BBDA5A058539.html
