4 dm-service-time is a path selector module for device-mapper targets,
5 which selects a path with the shortest estimated service time for
8 The service time for each path is estimated by dividing the total size
9 of in-flight I/Os on a path with the performance value of the path.
11 in a path-group, and it can be specified as a table argument.
13 The path selector name is 'service-time'.
15 Table parameters for each path: [<repeat_count> [<relative_throughput>]]
17 path before switching to the next path.
20 <relative_throughput>: The relative throughput value of the path
21 among all paths in the path-group.
24 If '0' is given, the path isn't selected while
27 Status for each path: <status> <fail-count> <in-flight-size> \
29 <status>: 'A' if the path is active, 'F' if the path is failed.
30 <fail-count>: The number of path failures.
31 <in-flight-size>: The size of in-flight I/Os on the path.
32 <relative_throughput>: The relative throughput value of the path
33 among all paths in the path-group.
41 Basically, dm-service-time selects a path having minimum service time
61 If calculated service time is equal, the path having maximum
