Abstract
Systems and methods for reducing the provisioned storage capacity of a disk or aggregate of disks of a storage appliance while the storage appliance continues to serve clients are provided. According to one embodiment, the size of the aggregate may be reduced by shrinking the file system of the storage appliance and removing a selected disk from the aggregate. When an identified shrink region includes the entire addressable PVBN space of the selected disk, the file system may be shrunk by relocating valid data from the selected disk elsewhere within the aggregate. After the valid data is relocated, the selected disk may be removed from the aggregate, thereby reducing the provisioned storage capacity of the aggregate by the size of the selected disk.
