After deploying centos7 on RAID 1, an error occurred during startup:

The same configuration and storage deployment of Ubuntu OS 20.04 was successfully completed.

Does anyone know why? I would appreciate any help.

Update test 1

After startup failure:
I press “e” when I boot to select the kernel
Then add SELinux = 0 in the startup item, and the OS can normally access the login interface.

But,

  • IP can be pinged
  • SSH cannot log in
  • Console user password cannot be logged in
