it looks like you have a patch for this problem in a queue somewhere (email found on ocfs2-dev: https://oss.oracle.com/pipermail/ocfs2-devel/2012-August/008677.html ) but its not in 3.6, any reason for the delay? I've been running that patch on 3.5 for a while now likely since around the time i found that email and its been working well
