After a cloud disk is manually mounted, the cloud disk is used as the CVM’s data disk. The default status is offline. You must perform initialization operations such as formatting, partitioning and creating a file system. We recommend you select an initialization method according to your actual use cases:
Common disk partition styles are Main Boot Record (MBR) and Guid Partition Table (GPT). If the disk partition format is changed after the disk is put into use, original data on the disk will be erased. Therefore, select an appropriate partition style according to actual needs.
Basics of the two partition styles are shown in the following table.
|Partition style||Maximum supported disk capacity||Number of partitions supported||Partition tool|
|MBR||2TB||Windows operating system: Disk managementLinux operating system:
|GPT||18EBCurrently, cloud disk supports a maximum capacity of 16TB||No limit on number of partitions||Windows operating system: Disk managementLinux operating system: parted tool|
Select the appropriate operations guide according to disk capacity and the CVM‘s operating system type:
