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,

> 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 ;)
