I continue to see people run DRDB clusters as VM guests. I personally don't get this. The only reason to do this is as a proof of concept and not for production. I run a DRDB cluster as a source of data storage system for a virtualization environment. It is based on physical machines for maximum performance. Depending on the I/O requirements of the DRBD system and it's applications running underneath it could make it very difficult for the virtualization hosts to supply the necessary I/O capability to support the required load.

Subject: [DRBD-user] DRBD on virtual machine

​​Hi list:

I need your help ... I have to migrate two physical servers with DRBD+Pacemaker+Corosync to virtual machines. On the new set of virtual machines I will can manage more hardware resources but, do you have any reason advise against using DRBD on virtual machines?

I hope your answers.

Thanks in advance.
