A super user fails to be created that have been create before initialization

Q: After the restore system factory_mode is used to initialize the storage, a super user fails to be created that have been create before initialization, the displayed tips indicating that the user name has been reserved

A:
Enter the Storage mode.
1. Confirm the residual user.
sudo cat /etc/passwd. Check whether the corresponding user name exists in the file.
2. Back up the /etc/passwd file.
sudo cp /etc/passwd /etc/passwd.bak.bak
3. Modify the passwd file.
sudo vi /etc/passwd
Delete the residual user line.
4. Perform the same operation on the other controller. ssh ibs_os_hs @127.127.127.1(0/1)
5. Open a window, log in to the system as the admin user, and create the new user.
6. After the new user is created successfully, delete the backup file.
sudo rm /etc/passwd.bak.bak
