At present we run only minor important virtual machines on these

Thanks for the advice!
Our installations are based on an article at the Proxmox-site
(wiki-article + forum-thread) that suggested to install drbd-utils,
version 8.3.10 because Proxmox' kernel is using this one. At present

fixes and enhancements that 8.3.11 brings.
