Oracle BUG，参考下列文档补丁25078431后未能解决
ALERT: root.sh Fails With "CLSRSC-400" While Installing GI 12.2.0.1 on RHEL or OL with RedHat Compatible Kernel (RHCK) 7.3 (Doc ID 2284463.1)
./gridSetup.sh -applyOneOffs /u01/patch/25078431/

进一步查看文档Doc ID 1369107.1确定ACFS支持的版本
ACFS Support On OS Platforms (Certification Matrix). (Doc ID 1369107.1)

根据文档，7.3版本需要补丁25078431，7.4版本需要补丁26247490，官方建议使用OL7 UEK kernel替代，随即找到了下列文档

Bug 26247490 - LINUX: Add ACFS support for OL7 update 4 using RHCK (Doc ID 26247490.8)

12.2.0.1及以上版本gridSetup.sh可以直接进行补丁操作

覆盖最新的OPatch工具

unzip p6880880_122010_Linux-x86-64.zip -d $GI_HOME
