Here is my plan to create a fault tolerant Joomla website using DRBD & NFS. And two WAN links a bonded T1 and DSL.
I Have three KVM machines all using DRBD storage using the Proxmox DRBD wiki.

1. Web server1
2. Web server2
3. MySQL server
Both Web server1 & Web server2 are using the same /home folder exported via NFS from an OpenFiler physical box.
Both web servers are using the same MySQL database running off the KVM MySQL server.
I am using a fail over service which will monitor my WAN links. Web server1 will always be the primary KVM serving content unless my bonded T1 goes down then web traffic will be diverted to web server2.
My intention of using an NFS mounted /home folder is to make any changes done to content on web server1 be also available to web server2.
Is this a sound plan or am I making this too complicated? Any thoughts or suggestions please share. Thank you!
