The maximum capacity of a Cloud Parallel File Storage (CPFS) file system is the value that you specify for the Capacity of CPFS File System parameter when you create the CPFS file system. If the capacity of the CPFS file system is used up, data cannot be written to the CPFS file system. We recommend that you increase the capacity of a CPFS file system before the capacity of the CPFS system is used up. This prevents your business from being affected by the issue that data cannot be written to the CPFS file system. This topic describes how to scale up a CPFS file system.
Prerequisites
A file system is created. For more information, see Create a file system.
