This document, using the standard login method (WebShell) as an example, provides a detailed guide on how to use the CFS Turbo file system on Linux clients. For more methods of logging into Linux instances, please refer to Logging into Linux Instances.
There is a compute instance that can communicate with the storage system and, in the VPC where CFS Turbo is located in CCN, port 988 of all IP addresses are opened bidirectionally.
If the information below is returned, installation is successful.
If the following message is returned, it indicates that the kernel version is not supported. In this case, you can submit a ticket to contact us.

The client version is not only related to the operating system version, but more importantly, it corresponds to the kernel. Currently, Turbo supports the kernel of the default public images in the compatibility list. If you have special kernel requirements, you can submit a ticket to contact us.
6. Log in to the CFS console and go to the File System page.
7. Click on the ID/name of the Turbo file system you wish to operate, and select the Mount Target Information tab.
8. In the "Mount Command" tab of the mount point information, click
to copy the required command.
9. Switch to the CVM instance to run the mount command copied.
The mount commands are described as follows. You can select one to fit your business needs:
If you want to support extended attributes and all operations to be executed synchronously by default (data will not be lost due to instance reboots, but the performance will be affected), copy and run the following command.
Example:
If you want extended attributes supported but don't need operations to be executed synchronously (some data cached in memory might be lost due to instance reboots, but the performance is good), copy and run the following command.
Example:
If you do not need the extended attributes supported or the operations to be executed synchronously (some data cached in memory might be lost due to instance reboots, but the performance is good): copy and run the following command.
Example:
sudo mount.lustre XXXXXXXXXXXXXXXXXXX
Note
If you want to mount the file system read-only, add the -o ro option when mounting.
You can mount a subdirectory of the file system by modifying the corresponding path in the mount command.
The unmount method is the same as that for a file system that uses the NFS protocol: Run umount /path/to/unmount.
