A game company deploys its business on a cloud server equipped with a Linux system, and uses the cloud hard disk service to back up its log data. At present, the operation and maintenance personnel find that the disk usage rate has reached 80%, and the cloud hard disk needs to be expanded. After the operation and maintenance personnel perform the capacity expansion operation, they find that the capacity of the cloud disk has not increased. Possible reason: The engineer only expanded the capacity of the disk, but did not format the expanded part, resulting in the hard disk space being expanded cannot be used normally.
