ORA-27300: OS system dependent operation:invalid_egid failed with status: 1

When i’m trying to create new database for RAC environment using DBCA,  It shows the error about invalid gid and diskgroup not mounted.

ORA-27300: OS system dependent operation:invalid_egid failed with status: 1
ORA-27301: OS failure message: Operation not permitted
ORA-27302: failure occurred at: skgpwinit6
ORA-27303: additional information: startup egid = 501 (oinstall), current egid = 502 (dba)

yes I’m realized, the problem may happen for permission issues of oracle binary execute file in grid home.

I check the permission for Grid Home/bin/oracle binary file

[oracle@racnode1 ~]$ ls -l /u01/app/11.2.0/grid/bin/oracle
-rwxrwxr-x oracle dba 210824714 Sep 14 07:58 /u01/app/11.2.0/grid/bin/oracle
[oracle@racnode1 ~]$

Stop ASM instance and then execute following command

[oracle@racnode1 ~]$ chmod 6751 /u01/app/11.2.0/grid/bin/oracle
[oracle@racnode1 ~]$ ls -l /u01/app/11.2.0/grid/bin/oracle
-rwsr-s--x 1 oracle dba 210824714 Sep 14 07:58 /u01/app/11.2.0/grid/bin/oracle
[oracle@racnode1 ~]$

Change the permission on second node grid home oracle binary file also If it was modified before.

Start ASM instance again and then now you try to create database using DBCA. It will successful.
