      configurations, then drbd9 really isnt for you<br>
      <br>
      That's why I still wonder why Proxmox removed 8.4.<br>
      I think a lot of low-mid sized setups are two nodes only, at least
      in development labs.<br>
      <br>
      Re-upgrading to 9.x is not an option now: I got back to 8.4 (as
      described before) with nodes in production state, near-to-no
      documentation supporting me and no certainty of the result.<br>
      DRBD 8.4 works perfectly for my needings, I won't relive that
      feeling in a short time ;)<br>
      Maybe I'll try DRBD 9.1 when available...<br>

          I'm not rushing to the defense of various parties, but I've
          been actively engaged in testing 9.0.x since its initial
          release and yes, its been a bear to make it become stable.
          However the rewards out weigh the troubles, a fully engaged
          mesh is very powerful approach and auto-promote makes it so
          much easier than traditional ocf. If you're doing 2 node ha 
          configurations, then drbd9 really isnt for you, its power is
          in multi-node,  and its higher throughput with the new
          networking stacks and auto-promote. <br>
          If you do want to realize the benefits and continue down the
          path, I'd recommend going to top-of-tree and building 9.0.1++,
          I have seen a quite a few fixes that the readme glosses over,
          and that may help you progress.<br>

                    It means I was not the alone...<br class="">
                    <br class="">
                    I've had the same issue a few months ago, I've
                    reported it here (and on Proxmox forums) but the
                    issue is still there.<br class="">
                    <br class="">
                    Linbit: nobody took care of it (however it's a
                    kernel crash, should be critical enough...)<br
                      class="">
                    Proxmox: a kernel with an updated DRBD module (still
                    DRBD 9.0) was released but the issue persisted.
                    Still wondering how a "non-production ready" feature
                    could end up in a "production ready" bundle like
                    Proxmox 4 without a choice to get DRBD 8.4 back.<br
                      class="">
                    <br class="">
                    I've sorted it out by downgrading DRBD module to 8.4
                    and building the kernel module + DRBD tools on my
                    own.<br class="">
                    This is the post on Proxmox forum with a backlink to
                    my blog post where I detailed the actions to
                    downgrade the module.<br class="">
                    I've also set up a script to run after each Proxmox
                    kernel upgrade, just in case.<br class="">
                    <br class="">
                    PS: still waiting for a feedback from Linbit/Proxmox
                    guys ;)<br class="">
