I have unusual behavior of function clone-start (Creating Flex clone) on 7-Mode. I have a thick Volume and thick Lun on it. I try to create FlexClone Lun with parameter space-reserve:false (i.e. clone will be thin provisioned) and use temporary snapshot (without existing snapshot). If the lun has used space more than available space on the volume, function has failed with error: "Clone operation failed to start: Volume is full or Volume crossed autodelete threshold..". For example: Volume: 1GB (Available: 300MB), Lun: 700MB (Used: 650MB) - FlexClone doesn't work Volume: 1GB (Available: 300MB), Lun: 700MB (Used: 100MB) - FlexClone works
But, If I do this operation and select existing snapshot, it works. Traditional lun clone works too.
