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>

<div class="">I am wondering about downgrading my whole Proxmox

<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="">
