Description Klaus Wenninger 2016-04-05 23:03:09 UTC
Description of problem:

SBD is not a super active upstream project but recently there had been
a couple of interesting changes that interfere with a lot of files
like stuff for pacemaker-remote and clarification of licensing in
most of the files.
So it is much cleaner and easier to support to base on the 
upstream version and patch what we want differently (like e.g. not
supporting block-devices for now) instead of doing it the other
way round.

Comment 3 michal novacek 2016-09-27 12:59:34 UTC
In our internal testing the following scenarios do work:

  * sbd as the only mean of fencing
    (internally: pacemaker,recovery,recovery-all,sbd,sbd-only,kill_sysrq_panic)
  * sbd as the secondary fencing, where the primary fencing works
    (internally: pacemaker,recovery,recovery-all,sbd,sbd-with-other-fencing,kill_sysrq_panic)
  * sbd as the secondary fencing, where the primary fencing never works (/bin/false)
    (internally: pacemaker,recovery,recovery-all,sbd,sbd-with-fake-fencing,kill_sysrq_panic)

It means that the following expected recovery behaviour of the cluster occurs
in the follwing scenarios:
    * killing node where the resource is active
    * causing one node to fall off the network
    * causing switch failure (nodes do not see each other)
    * killing random (one or more) node:
        * less than quorum
        * more than quorum
    * killing pacemaker on one or more nodes

Marking verified.
