Drbdmanage provides various commands to check the state of your cluster.
These commands start with a list- prefix and provide various filtering and
sorting options. The --groupby option can be used to group and sort the
output in multiple dimensions. Additional output can be turned on by using the
--show option. In the following we show some typical examples:
# drbdmanage list-nodes # drbdmanage list-volumes --groupby Size # drbdmanage list-volumes --groupby Size --groupby Minor # drbdmanage list-volumes --groupby Size --show Port
