1. Validate the <GRID_HOME> by using cluvfy tool.
$ cluvfy comp software -n all -verbose
This though only validates the binary files and theirs permissions. This is mentioned in unpublished bug 18407533 (closed as not a bug).
2. Check the permissions from the following 2 files which are created during Grid Infrastructure installation.
In $GRID_HOME/crs/utl (for 11.2 and 12.1.0.1) and <GRID_HOME>/crs/utl/<hostname> (for 12.1.0.2) directory:
- crsconfig_dirs which has all directories listed in <GRID_HOME> and their permissions
- crsconfig_fileperms which has list of files and their permissions and locations in <GRID_HOME>.
3. The permissions can be reverted back to original values with rootcrs.pl or roothas.pl . For versions 11.2.0.3.6 and higher, there is an option -init:
Reset the permissions of all files and directories under Oracle <GRID_HOME>. Please ensure CRS is not running while performing the followings:
For 11.2:
For clustered Grid Infrastructure, as root user
# cd <GRID_HOME>/crs/install/
# ./rootcrs.pl -init
For Standalone Grid Infrastructure, as root user
# cd <GRID_HOME>/crs/install/
# ./roothas.pl -init
For 12c:
For clustered Grid Infrastructure, as root user
# cd <GRID_HOME>/crs/install/
# ./rootcrs.sh -init
Need to add or modify executable permissions of crsctl binary , if modified after execucting rootcrs.sh -init as per the BUG 21032304 - LNX64-12C-UD: SOME FILES NOT EXECUTABLE AFTER EXECUTING "ROOTCRS.SH -INIT"
For Standalone Grid Infrastructure, as root user
# cd <GRID_HOME>/crs/install/
# ./roothas.sh -init
简便方法：
getfacl 、setfacl命令
a. 在节点2上获取文件及目录的权限:
# getfacl -pR /oracle > backup.txt
b. 拷贝 backup.txt 至节点1
c. 替换backup.txt中的rac2为rac1、ASM2为ASM1、orcl2为orcl1
vi bakcup.txt
:1,$s/rac2/rac1/g 回车 (:n,$s/ rac2/ rac1/g 替换第 n 行开始到最后一行中每一行所有rac2为rac1)
d. 在节点1上恢复权限（切到backup.txt目录下）
# setfacl --restore=backup.txt
e. crsctl start crs
f.srvctl start instance -d orcl -i orcl1
g. 检查验证。
然后去检查节点1上的权限是否已经恢复,包含用户,group,acl,suid,sgid等.
重启！
总结：/oracle 目录被修改之后
1 、srvctl stop instance -d orcl -i orcl1
2 、停止asm实例 停不下来 kill -9 pid of asm_smon_+ASM1
3 、停止crs 停不下来 kill -9 pid of /oracle/grid/crs_1/bin/crsd.bin reboot
4 、crsctl stop crs -f
5 、恢复目录权限：
a. 在节点2上获取文件及目录的权限:
# getfacl -pR /oracle > backup.txt
b. 拷贝 backup.txt 至节点1
c. 替换backup.txt中的rac2为rac1、ASM2为ASM1、orcl2为orcl1
vi bakcup.txt
:1,$s/rac2/rac1/g 回车 (:n,$s/ rac2/ rac1/g 替换第 n 行开始到最后一行中每一行所有rac2为rac1)
d. 在节点1上恢复权限（切到backup.txt目录下）
# setfacl --restore=backup.txt
6 、crsctl start crs
7 、srvctl start instance -d orcl -i orcl1 8 、检查验证。
