That's why I still wonder why Proxmox removed 8.4.
I think a lot of low-mid sized setups are two nodes only, at least in
development labs.
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.
DRBD 8.4 works perfectly for my needings, I won't relive that feeling in
a short time ;)
Maybe I'll try DRBD 9.1 when available...

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.
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.

Hi Claudio,
I wonder the same as you and I’m a little bit afraid about the
production ready thing…
I am wondering about downgrading my whole Proxmox installation to
have a stable system rather than using something that can brake any
day with a simple update… Do you think the version 4 features worth
the risk and I should go your way ?
Thank you for your answer again
Best regards,

Welcome aboard, and thanks for bringing back an issue that nobody
took care of since now.
It means I was not the alone...
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.
Linbit: nobody took care of it (however it's a kernel crash, should
be critical enough...)
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.
I've sorted it out by downgrading DRBD module to 8.4 and building
the kernel module + DRBD tools on my own.
This is the post on Proxmox forum with a backlink to my blog post
where I detailed the actions to downgrade the module.
I've also set up a script to run after each Proxmox kernel upgrade,
just in case.
PS: still waiting for a feedback from Linbit/Proxmox guys ;)
