FAQ
Can a single cloud disk be mounted to multiple cloud hosts simultaneously?
For security reasons, each cloud disk only supports being mounted to one cloud host.
What regions are available for purchasing cloud disks?
Please refer to: Product Introduction - Product Limits
Are there any restrictions on the use or purchase of cloud disks?
- The maximum number of cloud disks that can be purchased in bulk at once is 10.
- The quota for a single account is 1000 cloud disks.
- Currently, there are no limits on the number of udisk cloud disks that can be mounted. However, we recommend not to mount more than 5 disks on a single cloud host.
- It is suggested not to partition the cloud disk on the cloud host in order to avoid affecting the expansion of the cloud disk.
Does the cloud disk support the Ark?
Yes.
Does the cloud disk support automatic unbinding from the cloud host?
No.
For data security reasons, we recommend that you manually unmount the cloud disk in the system before unbinding the cloud disk through the console.
Can the cloud disk be used as a system disk?
Yes. You can choose to use the cloud disk to create a cloud disk host during the process of creating a host.
The default size of the cloud disk system disk is 20GB for Linux and 40GB for Windows.
Note: The cloud disk system disk does not support separate mounting, unmounting, expansion, deletion, cloning, snapshot, Ark, renewal, or changing business group functions.
Does the cloud disk system disk support mirroring?
Yes, the cloud disk host supports mirroring.
Can self-built LVM be used on a cloud disk data disk?
Yes.
However, it is suggested not to build your own LVM or other logical volumes, as snapshots are applied to each independent disk, and using LVM after its creation will lead to data differences after the rollback of snapshots.
Cloud disks that have been added to PV currently do not support expansion, and unmounting cloud disks may cause LVM errors.
How to expand the size if I have built my own LVM?
You can achieve the purpose of expansion by applying for a new cloud disk and adding it to PV.
