DRBD (Distributed Replicated Block Device) is a distributed storage system for the Linux platform. It is a way of sharing block devices over the network for building high availability clusters. You may share your question and experience in this post as comments. Thank you.

I want to export a block device (sda1) from one host (h1) to another, where on target host (h2), I will use the exported block device (h1da1) as a mirror of a local block device (h2da5). Simultaneously, I want to export another block device (h2da1) for 2nd host to be exported to the 1st host and mirrored with local device (h1da5) in the 1st. How do I do that? Assumed both running identical release and distro of Linux.
Supplementing with DRBD configuration file would be appreciated. Thanks in advance.
