<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>

Hi Claudio,

<div class="">I wonder the same as you and I’m a little bit

<div class="">I am wondering about downgrading my whole
Proxmox installation to have a stable system rather than

Do you think the version 4 features worth the risk and I
should go your way ?</div>

<div class="">Welcome aboard, and thanks for bringing
back an issue that nobody took care of since now.<br
class="">
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="">
