Take troubleshooting measures based on possible causes.

Solution

• Cause 1: The file system is abnormal.

  Log in to the management console. On the Scalable File System page, check whether the file system is in the Available state.

  • If yes, go to Cause 2.
  • If no, see The File System Is Abnormal to restore the file system to the available state, and then access the file system again.
• Cause 2: After a forcible unmount operation on the ECS, mount fails.
  1. This problem is caused by an inherent defect of ECSs. Restart the ECS to resolve this problem.
  2. Check whether the file system can be properly mounted and accessed.
     • If yes, no further action is required.
     • If no, contact technical support.
