    Examples

    The following example displays information about all replication rings in a two-node cluster:

    cluster1::*> cluster ring show
    Node      UnitName Epoch    DB Epoch DB Trnxs Master    Online
    --------- -------- -------- -------- -------- --------- ---------

    node1     vifmgr   1        1        350      node0     secondary
    node1     bcomd    1        1        56       node0     secondary
    node1     crs      1        1        88       node0     secondary
