Bare Metal Data Disk_Linux

If the host has not previously partitioned and only uses bare disk formatting, the following method can be used for expansion.

Note:

Please confirm before disk expansion operation, if there is data in the data disk, it is recommended that you backup the data first. The cloud disk can only be expanded when it is in an available state. Since the cloud disk needs to be uninstalled, it will interrupt your business, so please operate carefully. </ WRAP>

Operation Information:

• The version of this example environment:

In this example, the mounting point of the cloud disk is /dev/vdb, please operate according to the actual situation. If you do not see the corresponding device, please check the mounting information and status of the cloud disk.
