39. trunk_init_check_occupying
# if check trunk space occupying when loading trunk free spaces # the occupied spaces will be ignored # default value is false # since V3.09 # NOTICE: set this parameter to true will slow the loading of trunk spaces # when startup. you should set this parameter to true when neccessary. #trunk file初始化时, 是否检查可用空间是否被占用 trunk_init_check_occupying = false |
