New options to prioritize specific drives about greyhole HOT 2 CLOSED

### Directory selection groups ###
# The groups you define here will be available to use in the 
# dir_selection_algorithm option(s) below.
# The group names (SATA, IDE, USB and Remote in the example below) can be 
# anything you'd like.
# Use one line per group, with the following syntax:
#   group name: one or more (comma-separated) storage pool directories
# If you ommit any storage pool directory from your groups, this directory 
# will NOT be used by Greyhole!

#   dir_selection_groups = SATA: /mnt/hdd0/gh
#                          IDE: /mnt/hdd1/gh, /mnt/hdd2/gh
#                          USB: /mnt/hdd3/gh
#                          Remote: /mnt/remote1/gh, /mnt/remote2/gh

# You can also define dir_selection_groups for specific shares:
#
#   dir_selection_groups[Photos] = SATA: /mnt/hdd0/gh
#                                  IDE: /mnt/hdd1/gh, /mnt/hdd2/gh
#                                  USB: /mnt/hdd3/gh

#### Storage Selection Algorithm ####
# available algorithms: random, most_available_space
#   most_available_space: use the directories with the most available space 
#     first, so that available space on all drives should become and stay 
#     balanced.
#   random: use a random directory with available space

    dir_selection_algorithm = most_available_space

# If you defined dir_selection_groups above, you'll want to use them here.
# Use the 'forced' keyword, then list the groups you want to use, in order, and 
# prefix each group name with the number of directories you want to use from 
# that group before using the next group.
# Use the 'all' keyword to indicate you want Greyhole to use all directories 
# from a specific group, before starting to use directories from the next group.
#
#   dir_selection_algorithm = forced (all SATA, 1xIDE, 1xUSB, 1xRemote) most_available_space

# You can also define dir_selection_algorithm for specific shares:
#
#   dir_selection_algorithm[Videos] = random
#   dir_selection_algorithm[Photos] = forced (1xSATA, 1xIDE, all USB) random
