Main Concepts

File System

A file storage instance obtained by the user through the console, API, etc. The file system is the entity where the user performs data management and other operations.

File System Name

A user-defined string, used to describe the usage scenarios, business types, etc. of a file system, which is easy to identify specific file system instances.

Capacity

The space size specified when purchasing the file system, the capacity remains unchanged before the expansion operation.

Remaining Capacity

The space size that the file system can use. As the number of files written in the file system and the number of directories created increases, the remaining capacity decreases. Expansion operations should be performed promptly when the remaining capacity falls below the level required for business operations.

Mounting Address

The IP address provided by the mount point for mounting operations, the mount operation is executed in the host through this address.

Expansion

When the remaining capacity of the file system cannot meet the business availability requirements, you can expand the file system. This operation has no effect on the application using the file system, and there is no need to shut down or uninstall operations.

Mount, Unmount

The mount operation is to display a UPFS file system instance as a disk partition in the host by executing the mount command in the host, and the user can mount the file system to the designated directory mounting point in the host.

The unmount operation is to detach a file system instance from the host. After unmounting, the operations previously conducted in the directory mount point will not be reflected on the UPFS file system.

File System URL

The file system URL is divided into two parts, the management service address, and the file system resource ID, separated by /.

• The management service address consists of multiple instances to form a high-availability group, each instance address is separated by ,, the value is ‘mounting address’ in the column of file system information shown in the console, as follows:

  So the management service address is: 100.64.240.97:10109,100.64.240.95:10109

• The file system resource ID is the ‘resource ID’ in the column of file system information shown in the console, as follows:

  So the file system resource ID is: upfs-yda506pemnb

The UPFS file system URL obtained from {{channelName}} is as follows: 100.64.240.97:10109,100.64.240.95:10109/upfs-yda506pemnb
