Cancel Releasing a Disk
After releasing a disk, the data remains on the disk until the RAID rebalance is complete. Cancel releasing a disk if the RAID rebalance has
not completed and the data is still on the disk. Canceling the release reassigns the disk to the disk folder to which it was previously
assigned.
