[PVE-User] [DRBD-user] Stability issue Proxmox4/DRBD9

[Jean-Laurent Ivars]

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,

> 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.
