I try to install oracle database 12c RAC on the RedHat 7.3,when I execute the script '/u01/app/12.2.0/Root.sh' on node 1, I got the error: CLSRSC-400: A system reboot is required to continue installing. I'm too helpless to resolve that error. If I reboot the system, the install will be interrupted.
THE LOG IS:

So I go to MOS to find out the reason, and I find two document :ACFS Drivers Install reports CLSRSC-400: A system reboot is required to continue installing (Doc ID 2025056.1) and How to Verify that the ACFS Driver is installed and loaded (Doc ID 1319263.1)，those document indicate that ：When installing the Grid Infrastructure software, it always tries to install ACFS drivers.
I check my environment use follow scripts：
[grid@raca1 ~]$ acfsdriverstate -orahome $ORACLE_HOME supported
And I got the follow response：
ACFS-9459: ADVM/ACFS is not supported on this OS version: '3.10.0-514.el7.x86_64' ACFS-9201: Not Supported
My system not support for ADVM/ACFS，means I can not install the ACFS drivers.
The ‘Doc ID 2025056.1’ indicate：These error messages can be ignored if ACFS will not be used or is not supported on the node. So I reboot my system and remove the file installed. Then I install again ，and no error appeared。
If node 2 appears the same error ，just reboot system and run the root.sh again.
