QNAP_config_disks — Tries to keep HDD silent using internal firmware
| QNAP_config_disks [-y|--sleep ] [-t|--timeout seconds] [not normally used can set a very low timeout to test] [-m|--mode fast|medium|powersave|test] [-p|--permanent ] [-v|--verbose] ...list of drives
| QNAP_config_disks [-h|--help][-V|--version]
This is an alternative to using QNAP_manage_disks(8). This would normally be the first mechanism to try.
Uses hdparm(8) to set the power saving features of the disks. If -p is used the settings are stored in /etc/hdparm.conf. NB the scripts which use /etc/hdparm.conf only recognise format like /dev/sd? and /dev/hd?.
Read the comments in the script, the behaviour of different disks can be very different. Some spindown almost as soon as it's possible, some hardy at all. Some disks spin up in response to checking something innocuous like their temperature.
-m, --mode
: One of fast, medium, powersave or test (default is medium)
Sets the style of powersaving for the disk depeding on whether saving power or fast access is the primary objective. Beware that some disks would stop/start every few seconds with the "wrong" settings which would quickly wear out the drive. If you cannot get a suitable setting with this command, try QNAP_manage_disks(8) instead.
testing is intended to be used as its name implies, the disk will spin down very quickly, if this is set as the permanent mode then this behaviour may damage the drive (due to frequent spin up/down).
-h, --help
: Prints brief usage information.
-v, --verbose
: Make output more verbose.
-t, --timeout seconds : Force a particular timeout. Useful in testing, dangerous to use with -p (as is testing mode)
-p, --permanent : Save settings so it persists across boot (be aware disk names are not fixed betwen boots)
-s, --sleep : Immediatly spin the disk down (useful in testing how active a disk is)
Getting the disk to spindonw is a primary goal of QNAPHomebrew. This is the "easy" way to do it, however it does seem to work for many brands of drive.
If you cannot do it using this mechanism try QNAP_manage_disks(8).
- /etc/hdparm.conf : Stores the persistant settings for disks.
