./roothas.sh -postpatch OR root.sh failing with CLSRSC-400: A system reboot is required to continue installing.

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.

I tried checking associated log files to get more details: /u01/app/crsdata/test-server01/crsconfig/hapatch_2019-05-27_02-37-02PM.log


> ACFS-9428: Failed to load ADVM/ACFS drivers. A system reboot is recommended.
> ACFS-9310: ADVM/ACFS installation failed.
> ACFS-9178: Return code = USM_REBOOT_RECOMMENDED
2019-05-27 14:37:41: ACFS drivers cannot be installed, and reboot may resolve this
2019-05-27 14:37:52: Command output:
> CLSRSC-400: A system reboot is required to continue installing.
>End Command output
2019-05-27 14:37:52: CLSRSC-400: A system reboot is required to continue installing.

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.

While Manually Installing a Patch ‘rootcrs.sh -patch’ Fails with – CLSRSC-400: A system reboot is required to continue installing. (Doc ID 2360097.1)

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)

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 šŸ˜‰

Hope u will find this post very useful.

Cheers
