Solution 1598353.1 : On Oracle Big Data Appliance RPM Validation Errors Reported in BDA_REBOOT_FAILED File

Applies to:

Big Data Appliance X3-2 Hardware - Version All Versions and later
Linux x86-64

Symptoms

On Oracle Big Data Appliance(BDA) cluster, some nodes report RPM validation errors in /root/BDA_REBOOT_FAILED file. Once the reboot is complete, executing bdachecksw/bdacheckcluster does NOT report any RPM validation errors reported during boot/startup.

Executing bdacheckcluster will report the nodes with errors within /root/BDA_REBOOT_FAILED file

ERROR: Last reboot failed on host bda1node02
ERROR: Last reboot failed on host bda1node04
ERROR: Last reboot failed on host bda1node05
ERROR: Last reboot failed on host bda1node06

Sample RPM errors reported in /root/BDA_REBOOT_FAILED file

ERROR: Required package python is is not valid : S.?..... /usr/bin/python
ERROR: Required package readline is is not valid : S.?..... /usr/lib64/libreadline.so.5.1
ERROR: Required package rpm is is not valid : S.?..... /usr/bin/rpm2cpio
ERROR: Required package ruby is is not valid : S.?..... /usr/bin/ruby
ERROR: Required package tcl is is not valid : S.?..... /usr/bin/tclsh8.4
ERROR: Required package tcsh is is not valid : S.?..... /bin/tcsh
ERROR: Required package tk is is not valid : S.?..... /usr/bin/wish8.4
ERROR: Required package zsh is is not valid : S.?..... /bin/zsh
ERROR: Required package ipmiflash is is not valid : S.?..... /usr/bin/ipmiflash
ERROR: Required package ipmitool is is not valid : S.?..... /usr/bin/ipmitool
ERROR: Required package R-core is is not valid : S.?..... /usr/bin/Rscript

Note:- RPM errors may vary from node to node.

Cause

The validation string "S.?.....", indicates that the size has changed (or could not be figured out) and the MD5 sum could not be calculated. This suggests that the file was temporarily inaccessible.

All affected files are binary executables or shared libraries. A background prelink process runs once per day iterating through all binaries. The errors seem to occur if prelinking happens during startup.

Solution

If the bdachecksw/bdacheckcluster returns NO errors after the boot is completed then the warnings reported in /root/BDA_REBOOT_FAILED file can be ignored.

Otherwise, execute /opt/oracle/bda/lib/bdastartup.sh script as root user to clear /root/BDA_REBOOT_FAILED file and generate /root/BDA_REBOOT_SUCCEEDED file.

Once the /root/BDA_REBOOT_SUCCEEDED file is generated then bdacheckcluster will NOT report any reboot failure error.
