I also can confirm that this is: 3.13.0-123-generic: /sys/kernel/config/cluster/ocfs2/heartbeat/dead_threshold 4.4.0-81-generic: /sys/kernel/config/cluster/ocfs2/heartbeat/threshold
So where does the change come from and what needs to adapt (kernel or ocfs tools). It was reported that upstream in the kernel this still would be dead_threshold. I compared: Trusty: git://kernel.ubuntu.com/ubuntu/ubuntu-xenial.git Xenial: git://kernel.ubuntu.com/ubuntu/ubuntu-xenial.git Upstream: git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git I found that on that level Upstream agrees to have dead_threshold just as trusty does. So why is Xenial off of that - I found an upstream commit [1] that broke it upstream. That broken state is in since 4.4 and fixed about now in 4.12 with commit [2]. There also is stable kernel activity on this at [3] for 4.11, [4] for 4.9 and [5] for 4.4 Given that pre-analysis I think it is the kernel team that has/want to look to include updates. I hope my analysis helps to do so, and I have reassigned by adapting the bug tasks accordingly.
