Mount a GPFS File System

After you mount a GPFS file system, CES instances or CKS cluster nodes can access data in the file system through a local directory.

Prerequisites

The GPFS file system is in the Running state.
The CES instance or CKS cluster node to be mounted is in the same region as the GPFS file system. GPFS file systems cannot be mounted across regions. Only compute nodes in the same region as the file system can mount the file system.
The local mount path has been planned.
- If you mount only a subdirectory in the file system, make sure that the subdirectory already exists.
- If multiple mounts exist on the same CES instance, each mount path must be unique.

Select the CES instance to which you want to mount the file system and configure the paths.

Parameter	Description
Mount path on CES	The mount path of the file system on CES. After the mount is complete, go to this path to access data in the file system.
FS path	The remote path in the file system. Enter `/` to mount the entire file system. Enter `/path_to_your_dir` to mount only a subdirectory in the file system.

Choose Confirm, and then check the mount result. If the mount succeeds, the result is displayed as success. If the mount fails, the dialog box displays an error message.

Log on to the console and open the Instances page.
Select the CES instance to which you want to mount the file system, open the actions menu, and choose Mount File System.

In the dialog box that appears, follow the prompts to complete the configuration.

Configuration item	Description
GPFS Mount Service	Select the GPFS mount service.
Bind File System	If you create a mount service, bind the storage volume to the corresponding file system.
Client Management	Select client nodes.
Mount File System	Configure the mount path.

Choose Confirm, and then check the mount result. If the mount succeeds, the result is displayed as success. If the mount fails, the dialog box displays an error message.

If you need to mount the file system manually on a server, use the following command format:

mount.xstor-gpfs -o tenantid=<tenant-id> xstor-<fsid>.<fsid>-001.aries:/ <mount-dir>

Where:

Example:

mount.xstor-gpfs -o tenantid=sXXXXXXyyyyyy xstor-01b12345.01b12345-001.aries:/ /data

If the mount fails, check the following items first:

Check item	Description
File system status	The file system must be in the `Running` state.
Region	The CES instance or CKS cluster node must be in the same region as the file system.
Local mount path	The mount path must not conflict with existing mounts.
Remote path	The subdirectory specified by FS path must already exist.

If the issue persists, record the error message and contact support.
