Please note that you open the section with the disk keyword.c-delay-target delay_target,
c-fill-target fill_target,
c-max-rate max_rate,resync-rate rate
Defines the bandwidth available for resynchronization. bsr allows general application I / O even during resynchronization. If resynchronization takes up too much bandwidth, application I / O can be very slow and this parameter can be avoided. This option only works if the dynamic resync controller is disabled.
c-plan-ahead plan_time
Dynamically control the speed of resynchronization. This mechanism can be used by setting the c-plan-ahead parameter to a positive value. The maximum bandwidth is limited by the c-max-rate parameter. The c-plan-ahead parameter defines how quickly bsr adapts to changes in the resynchronization rate. It should be set to at least 5 times the network round-trip time (RTT). When c-fill-target is defined, it tries to fill the buffer with a defined amount of data along the data path, and has a defined delay if c-delay-target is defined. The common value range for c-fill-target for "normal" data paths is 4K to 100K. If you use drx, we recommend using c-delay-target instead of c-fill-target. The c-delay-target parameter is used when the c-fill-target parameter is undefined or set to 0. The c-delay-target parameter should be set to at least 5 times the network round trip time. The c-max-rate option should be set to either the available bandwidth or the available disk bandwidth between the bsr host and the system hosting drx. The default values for these parameters are: c-plan-ahead = 20 (in 0.1 second increments), c-fill-target = 0 (in sector increments), c-delay-target = 1 (in 0.1 second increments) and c-max-rate = 102400 (KiB / s unit).

Nodes that are primary and source of synchronization must schedule application I / O requests and synchronization requests. The c-min-rate parameter limits the amount of bandwidth available for resynchronization I / O. The rest of the bandwidth is used for replication of application I / O. If the c-min-rate value is 0, it means there is no limit to the resynchronization I / O bandwidth. This can significantly slow down application I / O. Use the value of 1 (1 KiB / s) for the lowest resynchronization rate. The default value of c-min-rate is 250 in KiB / s.
resyncc-max-rate max_rate
Defines Sets the maximum bandwidth available used for resynchronization . bsr allows general application I/O even during resynchronization. If resynchronization takes up too much bandwidth, application I / O can be very slow and this parameter can be avoided. This option only works if the dynamic resync controller is disabled. bsr trades off replication bandwidth to maintain synchronization bandwidth from c-min-rate to c-max-rate.
