Issue

ONTAP System Manager shows negative value as a volume size
The REST API /api/storage/volumes?name=vol1&fields=space returns a negative value for space.available on a specific volume which has space available

{

{

"uuid": "a12345xx-x12x-123d-1234-x1x123xx12xx",

"name": "vol1",

"space": {

"size": 57174604644352,

}}}],
