  • Closed as program error.

Error description

  • When a cluster disk is parted into 2 or more partitions, only
    the first partition drive letter is correctly obtained and
    random values return for the successive partitions.
    
    The returned random values may cause FastBack client to
    erroneously report owning of a cluster disk for the passive
    node. Snapshots would fail with time out error for volumes on
    this cluster disk, and log could be found in FastBack Server:
     AGI_SendMonitorCtrlInternal: command sent to 2 agent(s)
