Setup DRBD before you make use of your storage. 2. Add DRBD to an existing system. I personally prefer to set up DRBD beforehand so as to not have to tamper with the device by adding metadata to it. Simply less to go wrong. According to the userguide, you can add metadata to a disk provided that there is sufficient space for the metadata. For more information, see the user guide: http://www.drbd.org/users-guide/ch-internals.html#s-metadata So, yes its possible to both run a single DRBD node, and add DRBD to an existing system to make it resilient.
