## defaults for module resource
##
## this module administrates the test resources

## the names of the resources used in the current test. Must be a subset of
## lv_config_lv_name_list (default-lv_config.conf)
## These resource are created on all hosts in main_host_list using the first
## host as primary and the followings as secondaries
resource_name_list=(lv-1-2)

## mount points of the data devices
## resource_set_globals_depending_on_resource_name_list fills the list
declare -g -A resource_mount_point_list

## resource indexed list of resource directories in main_mars_directory
## resource_set_globals_depending_on_resource_name_list fills the list
declare -g -A resource_dir_list

## resource indexed list of filesystem types of the data devices
## resource_set_globals_depending_on_resource_name_list fills the list
declare -g -A resource_fs_type_list

## resource indexed list of resource specific messages to be grepped for in
## abnormal situations
## resource_set_globals_depending_on_resource_name_list fills the list
declare -g -A resource_mars_dir_full_err_pattern_list

## because some global variable depend from other global variables
##  (e.g. resource_mount_point_list from resource_name_list) it's
## necessary to give *.conf  files the possibility if they change a global
## variable to reset all dependend global variables.
## This can be done by a call to this function.
