# SLOW NAS CONFIGURATIONS - By Rapitharian
##########################################################
#This Feature was added to the program to provide a fix for slow NAS devices similar to the Drobo and Synology devices. SMB and Home NAS devices.
#This Feature enables the device to perform tasks (Deletes/data save for large files) and has the script wait for the NAS to catchup.
#This code has been in production on the authors systems for the last 2 years.
# Enable use of the NFS IO HACK for all NAS commands 1=yes, 0=no
# 0 uses the script in it's original state.
ENABLE_NFS_IO_HACK=0
# Set this value to determine how many times the script tries to work arround I/O errors each time the NAS slows down.
# The script will skip past this loop if the NAS is responsive.
NFS_IO_HACK_LOOP_MAX=10
# This value determines the number of seconds to sleep, when the NFS device is unresponsive.
NFS_IO_HACK_SLEEP_TIMER=60
# ONLY USE THIS WITH EXTREMELY SLOW NAS DEVICES!
# This is a Brute-force/Mandatory delay added on top of any delay imposed by the NFS_IO_Hack.
# Set a delay timer to allow the NFS server to catch up to GhettoVCB's stream, when the NAS isn't responding timely.
# This acts like a cooldown period for the NAS.
# The value is measured in seconds. This causes the script to pause between each VM.
