A device name (mount point) is the location of a cloud disk mounted to the CVM instance on the disk controller bus. The selected device name matches the disk device number in Linux and matches the disk sequence number of the disk manager in Windows.
No. You can mount up to 20 cloud disks to the same CVM, but you cannot mount the same cloud disk to multiple CVMs. You can only share data by unmounting the cloud disk from CVM A and then mounting it to CVM B.
Yes. After you purchase a cloud disk, you must mount it to a CVM instance in the same availability zone, and then initialize it by formatting, partitioning, and creating the file system before using it as a data disk. For more information, see Mounting Cloud Disks and Initializing Cloud Disks.
If you purchase a data disk separately, you must partition, format, and mount it to an instance to view and use its storage space. For more information, see Mounting Cloud Disks and Initializing Cloud Disks.
A maximum of 20 data disks can be mounted to one CVM instance.
Make sure that the CVM instance has not been released and ensure that it is in the same region and availability zone as the cloud disk is in.
No. A cloud disk can only be mounted to or unmounted from a CVM instance in the same availability zone as the cloud disk is in.
Data in cloud disks will not be modified during mounting or unmounting. To ensure data consistency, we recommend that you follow the steps below:
umountcommand on the cloud disk. After the command is executed, log in to the CVM Console to unmount the cloud disk.
