If you are getting error related to LVE then this error shows, this issue can be solved due to non-LVE kernel is used. You can use below command for that:

Code: 
grep "Kernel command line: BOOT_IMAGE=" /var/log/messages
You will get the below output :

Code: 
Sep 30 03:10:18 hostname kernel: Kernel command line: BOOT_IMAGE=/boot/vmlinuz-3.10.0-1062.1.2.el7.x86_64 root=UUID=ef0ca717-b580-42e8-b609-e929b5234713 ro crashkernel=auto rhgb net.ifnames=0 biosdevname=0

You will find “Lve” in the last line of code it means non-LVE kernel is in use and functions of LVE are not working.
