[dm-devel] [PATCH 4/4] multipath-tools: change default path_grouping_policy from failover to multibus
Xose Vazquez Perez

Thu Aug 18 17:58:16 UTC 2016
Default value is: failover
1 .pgpolicy = FAILOVER,
2 .pgpolicy = GROUP_BY_SERIAL,
25 .pgpolicy = MULTIBUS,
47 .pgpolicy = GROUP_BY_PRIO,
failover is only used by 1 device: IBM/3303 NVDISK
I hope it's reasonable. If someone disagrees, drop it.
