I have built 8.4 drbd module for kernel 4.2.8-1-pve, together with the latest drbd-utils (with support for 84 version), then downgraded resources to 8.4. I've run the same IO-intensive tests as before (on 9.0) for more than 24 hours: no issues. 9.0 crashed after no more than 3/4 minutes. My two-nodes Proxmox is actually running since 3 days without any issue. Should be great, for whom like me with a simple two-nodes setup, to have a kernel with drbd 8.4 instead of 9.0; is it possible? Otherwise I'll create a script to automate buiilding process each time I'll update the kernel in the future. PS: since there's near-to-no ducumentation available on DRBD downgrading, I'll will write a post with detailed instruction (I took detailed notes while building and reconfiguring my nodes).
