HI I have configured two storage Lun through NFS one is Master which is having capacity of 2TB and the other is having 1TB. Now the issue when ever user deploy a vm automatically vm is getting deployed in master lun which is running out of HDD space and the vm is not getting deployed in the other Lun ,is there any setting to do that vm should get deployed in other LUN ? Thanks, Nagaraju
