Initialization Scenarios

Last updated: 2023-12-21 21:16:06
The cloud disks created through the console are manually mounted to your CVM and used as data disks in Online status by default. To use the disks, you need to initialize them first, including formatting, partitioning, and creating file systems. The initialization method varies by actual use scenario as shown below:
If the entire disk is presented as one independent partition (that is, there are not multiple logical disks such as D disk/vdb1 and E disk/vdb2), we strongly recommend you not use partitions, and directly create the file system on bare devices.
If the entire disk needs to be presented as multiple logical partitions (that is, there are multiple logical disks), you need to perform the partitioning first, then create the file system on a partition.
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
4 primary partitions
3 primary partitions and 1 extended partition
Windows operating system: Disk management
Linux operating system:
fdisk tool
parted tool
Currently, cloud disk supports a maximum capacity of 32TB
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:
For disk capacity less than 2TB:
For disk capacity larger than or equal to 2TB:
