This topic describes the usage notes and mounting methods of Apsara File Storage NAS file systems. Take note of the following points before you mount a file system:
Usage notes
- Before you mount a file system, you have Create a permission group and add rules for the permission group and Create a mount target.
- If the mount target of a file system resides in a virtual private cloud (VPC), you can mount the file system only on an Elastic Compute Service (ECS) instance in the VPC. The private IP address of the ECS instance must be authorized in a rule of the permission group that is attached to the mount target.
- If the mount target of a file system resides in the classic network, you can mount
the file system only on an ECS instance of the same Alibaba Cloud account. The private
IP address of the ECS instance must be authorized in a rule of the permission group
that is attached to the mount target. For more information, see Manage a permission group.
Note If a mount target resides in the classic network, only the ECS instances in the classic network can access the mount target.
- You can mount a General-purpose NAS file system across multiple zones. We recommend that you mount an Extreme NAS file system on an ECS instance that resides in the same zone as the file system. Otherwise, the performance of the Extreme NAS file system is reduced.
- You can create a mount target only in a VPC for an Extreme NAS file system. Extreme NAS file systems support only the Network File System (NFS) protocol.
Scenarios
- The following topics describe how to mount a file system on an ECS instance:
- Use the NAS console to mount a file system
- Run the mount command to mount a file system
- If you want to mount a file system by using Container Service for Kubernetes (ACK),
use the methods that we recommend in Recommended mount methods.

- Use the CSI driver to mount a dynamically provisioned NAS volume
- Use the FlexVolume driver to mount a statically provisioned NAS volume
