[DRBD-user] How to detach the DRBD Block Device.

[Robert Altnoeder]

>From your current state (StandAlone, Attached, Primary), these are your
options:

1) Connect the resource and then detach the local volume:
    drbdadm connect <res>
    drbdadm detach <res>
    You cannot detach and disconnect at the same time if the resource is
in the Primary role

2) Unmount the resource, change role to Secondary, then detach
    umount <mountpoint>
    drbdadm secondary <res>
    drbdadm detach <res>
    In the Secondary role, you can disconnect and detach, because the
resource's data ist not in use.
    That would leave the resource in 'Unconfigured' state.
