One of our Exadata Database server system got hung at below error while booting.
dracut: Mounted root filesystem /dev/mapper/VGExaDb-LVDbSys1
dracut: Loading SELinux policy
dracut: SELinux: Could not open policy file <= /etc/selinux/targeted/policy/policy.26: No such file or directory
No such file or directory
dracut: Switching root
When I check, found the configuration files are missed under / filesystem.
For correction the problem please take the system to rescue mode as below link.
Copy back the content to /etc/ folder, In this case, [otherwise, need to compare the / filesystem folders with identical/similar system ]
cp -rp /root/etc/* /etc/
Exit from rescue mode and boot the system normal. Please also check metalink Doc ID 2572422.1
