For pacemaker, this is a duplicate of: https://bugs.launchpad.net/bugs/1439649
So, instead of marking it as duplicate, since it had charm work, I'm removing pacemaker from the bug and leaving this comment: https://bugs.launchpad.net/ubuntu/+source/pacemaker/+bug/1439649/comments/20 """ >From Corosync 2.4.1 Release Notes: This release contains fix for one regression and few more smaller fixes. """ During 2.3.6 development the bug which is causing pacemaker to not work after corosync configuration file is reloaded happened. Solution is ether to use this fixed version (recommended) or as a quick workaround (for users who wants to stay on 2.3.6 or 2.4.0) is to create file pacemaker (file name can be arbitrary) in /etc/corosync/uidgid.d directory with following content (you can also put same stanza into /etc/corosync/corosync.conf): uidgid { gid: haclient } """ Anyone relying in Trusty or Xenial corosync: corosync | 2.3.3-1ubuntu1 | trusty corosync | 2.3.3-1ubuntu4 | trusty-updates corosync | 2.3.5-3ubuntu1 | xenial corosync | 2.3.5-3ubuntu2.3 | xenial-security corosync | 2.3.5-3ubuntu2.3 | xenial-updates should apply the mitigation above, like discovered previously by commenters of this bug. Note: Trusty is already EOS so I'm marking it as "won't fix". Xenial should include the mitigation in a SRU.
