If the instance OS environment is abnormal, you can reinstall the instance system. Currently, reinstalling the system does not support selecting a different OS image.
Reinstalling the system is a high-risk operation. After the system is reinstalled, data on the CES instance system disk will be deleted and cannot be recovered. Before reinstalling, ensure that any data you need to retain has been backed up.

​
Pre-Operation Confirmation

  • Reinstalling the operating system will interrupt tasks currently running on the instance.
  • After the operating system is reinstalled, data on the CES instance system disk will be deleted and cannot be recovered. Back up any data you need to retain before proceeding.
  • If the instance has a GPFS file system mounted, confirm whether reinstalling the operating system will affect the mount configuration.

​
Procedure

  1. Log in to the GPU Cloud console and go to the Instance page.
  2. On the GPU Instance or CPU Instance tab, locate the instance whose operating system needs to be reinstalled.
  3. Click More Actions in the instance Actions column, and select Reinstall System.
  4. In the confirmation dialog box, review the instance information and risk notice, then confirm the reinstallation.
  5. Return to the instance list and check the reinstallation status. After reinstallation is complete, check whether you can log in to the instance and whether the required network, storage, and GPU capabilities are available.

Frequently Asked Questions

Why can't I see the Reinstall System option?
