From what I understand, the o2hbmonitor utility monitors if the cluster is up by scanning files in the /sys/kernel/debug directory, which the kernel creates when you use the debugfs facility. If the debugfs files do not exist or configured thresholds exceed than o2hbmonitor prints a message. The files are all virtual and do not occupy any space similar to procfs and systemfs.
