Hi, So it seems that my setup was not working because SELinux was not disabled. Once I disabled it, my web server displays the correct index.html. In my master node's /var/www/html, I see the correct index.html, but in the slave's /var/www/html I still see the old index.html. Once I do a failover and the slave becomes the master, I see the correct index.html in the new master's /var/www/html, and the website works as expected with no downtime.
Is this the correct behavior? I was under the impression that both nodes will reflect the same contents, and whatever is changed on the master will be replicated in near real time in the slave. Also, I wish now with to put a mySQL database in the DRBD block device. What would the procedure be to do so? I suppose it would be similar to the Apache example, except /var/www/html would be replaced by wherever the DB is installed?
