# Bees works on a filesystem as a whole. The
# filesystem's unique UUID is used as
# identifier
# Use `btrfs filesystem show` to display known
# btrfs filesystems.

# The size of bees hash table in bytes.
# Must be a multiple of 128KiB. See the chart
# below for recommended sizes.
hashsize="$((128*1024*1024))" # 128MiB

# Set bees loglevel.
# 1 is lowest, 8 is most verbose.
# WARNING: a high loglevel increases logfile size greatly.

# Location of the bees status file
#statusfile="/run/bees/${fsuuid}.status"

# Custom logfile location

## OpenRC resource control
# ionice values are  0 none, 1 real-time,
# 2 best effort and 3 idle.
SSD_IONICELEVEL=3

# nice can be -20 to 19, where 19 is lowest priority.

# Out Of Memory score adjustment. A high value increases
# the likelihood that the process will be terminated
# during OOM condition. Allowed values -1000 to 1000.
SSD_OOM_SCORE_ADJ=0

## Hash table sizing
# The relative size of the hash table
# compared to the data set determines
# the achievable dedup block size. 
# A good starting point is 128K.
#
# A = unique data size
# B = hash table size
# C = average dedupe extent size
#   A  |   B   |   C

#  1TB |   4GB |    4K
#  1TB |   1GB |   16K
#  1TB | 256MB |   64K
#  1TB | 128MB |  128K <- recommended
#  1TB |  16MB | 1024K
# 64TB |   1GB | 1024K
