Recently I was doing fresh Grid Infrastructure(GI) 12.2 install on one of our UAT boxes, wherein I was facing strange issue.
Both “root.sh” & “./roothas.sh -postpatch” exiting with below error/warning:
CLSRSC-400: A system reboot is required to continue installing.
test-server01:/u01/app/12.2.0.1/grid/bin # cd $ORACLE_HOME/crs/install test-server01:/u01/app/12.2.0.1/grid/crs/install # ./roothas.sh -postpatch Using configuration parameter file: /u01/app/12.2.0.1/grid/crs/install/crsconfig_params The log of current session can be found at: /u01/app/crsdata/test-server01/crsconfig/hapatch_2019-05-27_02-22-25PM.log 2019/05/27 14:22:30 CLSRSC-329: Replacing Clusterware entries in file '/etc/inittab' 2019/05/27 14:23:18 CLSRSC-400: A system reboot is required to continue installing.
A simple instruction given by above warning was to reboot machine & retry. I did ask server admin to reboot machine but subsequent rerun of command failed with the same error.
test-server01:/u01/app/12.2.0.1/grid/crs/install # ./roothas.sh -postpatch Using configuration parameter file: /u01/app/12.2.0.1/grid/crs/install/crsconfig_params The log of current session can be found at: /u01/app/crsdata/test-server01/crsconfig/hapatch_2019-05-27_02-37-02PM.log 2019/05/27 14:37:07 CLSRSC-329: Replacing Clusterware entries in file '/etc/inittab' 2019/05/27 14:37:52 CLSRSC-400: A system reboot is required to continue installing.
I tried checking associated log files to get more details: /u01/app/crsdata/test-server01/crsconfig/hapatch_2019-05-27_02-37-02PM.log

So this was definitely due to issue with ACFS drivers.
I found below MOS documents related to my issues but nothing was exactly matching with my situation or operating system.
In our environment, we don’t use ACFS file system, so it was not the real problem in my case & we can always get ACFS drivers explicity if we need it in the future.
After reading all the logs I found /u01/app/12.2.0.1/grid/lib/acfstoolsdriver.sh is being called for ACFS driver installation.
I changed following code from
# Now run command with all arguments!
exec ${RUNTHIS} $@
to
# Now run command with all arguments!
#exec ${RUNTHIS} $@
exit 0
After changing above code, “./roothas.sh -postpatch” completed without errors/warning & I was able to complete GI installation successfully.
Note: This workaround is only applicable when ACFS is not being used in the environment so it can be implemented with the forewarning that there is implied risk which one must accept š
Hope u will find this post very useful.
Cheers
