Thanks for the informative read Florian. <br><br>Martin, I agree with you that a hardware based shared storage solution is ideal but our budget doesn't allow for it so I have to make this work with DRBD.<br><br>This might sound naive but is fencing even required in my scenario? <br>
Two apache Web servers with IP fail over handled by the hosting provider. Dual Primary DRBD device with OCFS2 shared storage. There is no load balancing so only one node will be actively writing and reading at any given time. Apache and DRBD will be active at all times on both servers and if the primary node fails, IP will manually be re-assigned to the secondary which will have all data available via DRBD/OCFS2. In my mind there is no requirement for fencing or even pacemaker based DRBD and Apache management. <br>
Is this a valid scenario? Or am I setting myself up for a fall?<br><br>Thanks<br><br>Lawrence<br><br><br><br><br><br><br><br><br><div class="gmail_quote">On 1 February 2012 18:32, Florian Haas <span dir="ltr"><<a href="mailto:florian@hastexo.com">florian@hastexo.com</a>></span> wrote:<br>
