Hello, I am posting here as a recommendation from an ocfs2-users response for my original post: http://oss.oracle.com/pipermail/ocfs2-users/2011-April/005046.html
Excerpt: I am running a two-node web cluster on OCFS2 via DRBD Primary/Primary (v8.3.8) and Pacemaker. Everything seems to be working great, except during testing of hard-boot scenarios. Whenever I hard-boot one of the nodes, the other node is successfully fenced and marked ³Outdated² * <resource minor="0" cs="WFConnection" ro1="Primary" ro2="Unknown"ds1="UpToDate" ds2="Outdated" /> However, this locks up I/O on the still active node and prevents any operations within the cluster :( I have even forced DRBD into StandAlone mode while in this state, but that does not resolve the I/O lock either. ...does anyone know if this is possible using OCFS2 (maintaining an active cluster in Primary/Primary when the other node has a failure? E.g. Be it forced, controlled, etc) Is ³qdisk² a requirement for this to work with Pacemaker? NOTE: On a reply to my original post (URL above) I also provided an example CIB that I have been using during testing.
