We are going to grow one of our DRBD resources by ~150GB. We use "meta-disk internal" so the MD shares the same disk as the drive itself. When we use the "drbdadm resize" tool to resize a disk, does the metadata also get re-calculated and grown to the required size(32Mb per 1Tb)? Or is there something I need to do in order to increase the metadata to the recommended amount?

I would imagine that using drbdadm resize would recalculate and create a larger space for MD, but I thought I would ask. I am having trouble finding my answer in the docs.
