It look like apache is unable to stat its document root.
Could you please show output of two commands:

getenforce
ls -dZ /var/www/html

on both nodes when fs is mounted on one of them?
If you see 'Enforcing', and the last part of the selinux context of a
mounted fs root is not httpd_sys_content_t, then run
'restorecon -R /var/www/html' on that node.
