I've just re-read your response on this issue.

To be clear, it's not NFS related, it's LVM2 related. The DRBD device
(/dev/drbd0) is an LVM Physical Volume (PV) and there are two logical
volumes on it that are mounted on the system. drbd-mc recognises the
logical volumes and displays them in the Disks layout, but believes they
are not mounted; although they are.

(Same remains for / (/dev/sda2))
