Hardware :: Automatically Powers Down The HDD After A While Of Inactivity To Save Electricity Or Disk Spinning?

May 29, 2011

I am curious about a particular matter. Recently I have purchased a small plug computer that I will use as a torrent server and networked file storage. The thing is I will attach an external HDD to this linux box. Now I am curious about something. The HDD is powered on while the box works, but once the work is done the disk seems to keep running and does not spin down automatically - even though there is no I/O happening.

My question is whether I should add a script that automatically powers down the HDD after a while of inactivity to save electricity or is it better to keep the disk spinning? How does spinning down a HDD affect its health?

Ubuntu :: Hard Disk Keeps Spinning?

Jun 19, 2011

I am a regular ubuntu user from 7.10 till now. Now I am using 11.04. This problem never happened with previous releases. When I open more than 4 windows in firefox or whenever I open "Ubuntu Software Center" the hard disk keeps spinning, mouse and keyboard are frozen. I tried to reboot from tty1. It takes around 3 minutes to get the command prompt after pressing Ctrl + Alt + F1. I reinstalled 11.04 several times. This problem is not solved. I have applied all the updates. What program is exactly causing this problem?

Ubuntu :: Allow Auto-log Off Feature Either An Extended Inactivity Time Or To Disable Inactivity-logouts

Oct 18, 2010

I would like to allow the auto-log off feature either an extended inactivity time or to disable inactivity-logouts.

I use my PC strictly at home, and have no security issues. I've set my username to no-password so that I just click [twice] to log back on. But I must do that to see the screen display - say to see what's playing on Pandora.

Can I set the auto-logout-time somewhere or disable the function?

Debian Configuration :: Hard Disk Won't Stop Spinning Up / Down

Feb 11, 2015

I've bought a new notebook. The hard drive won't stop spinning down and then spinning up again during load. I don't want HD power saving, so I disabled it within

1. /etc/hdparm.conf
Code: Select all# -B apm setting
apm = 255
# -B apm setting when on battery
apm_battery = 255

It didn't work. I can still hear the HD spin up. It's annoying in a video game because things just suddenly stop for a second.

2. /etc/udev/rules.d/50-hdparm.rules

Code: Select allACTION=="add", SUBSYSTEM=="block", KERNEL=="sda", RUN+="/usr/bin/hdparm -B 255 -S 0 /dev/sda"

This was also every tip I could find during RTFM.

Other specs:

Acer Aspire E5-521G-88A8 Notebook
AMD A8-6410 APU
AMD Radeon R5 2 GB VRAM
hdparm model number: ST1000LM024 HN-M101MBB

Debian Jessie

Ubuntu :: Unable To Mount XFS After Electricity Failure

Dec 16, 2010

I'm using Ubuntu 10.10 x86_64, with 2T HDD x5 grouped as RAID5 using RAID controller (dell perc 6/i), result in a 8TB disk, and I put it to a single partition in XFS. Just now one light bulb went wrong and caused whole house power fail, sadly during that time I'm copying some data to that partition. After I clear the power issue and turn on the computer, the partition still can mount, so I continue copying, and that gives me some IO error. I assume it is some kind of problem that need a file system check, so I unmount it, and run xfs_repair.

However xfs_repair shows the partition has not been unmount so I restarted the computer. After restarting, during the loading screen the system prompt me that it cannot find the file system, and I pressed 'S' to skip (btw 'M' for manually maintenance, but I didn't try) Then there comes the problem: the partition cannot be mounted anymore. I tried using palimpsest (the disk utility) to check, the partition shows normally (i.e., there's a 8T disk with a single partition in XFS), but when I try to mount it, the first time I click 'mount' results in nothing, repeat click will get an error 'The device is busy: A job is pending on /dev/sdb1'.

Checking the process running I found this:
process 'mount', status 'uninterruptible', command line 'mount /dev/sdb1', waiting channel 'call_rwsem_down_write_failed'.
Also other operations with that partition does not work, such as xfs_repair or mount, will just halt (and the waiting channel is 'get_sb_bdev')

Software :: Command To Automatically Save Screenshot After Pressing Hotkey?

Aug 11, 2010

I've been pulling my teeth out trying to find out a way to automatically save a screenshot to a folder by pressing a hotkey, and append a counter or timestamp to the end of the filename. I found this which works well

import -window root ~/screenshot.png

but I need a way to add a counter so that it doesnt constantly override the same file when I press the hotkey, but will save a new screenshot in the same folder.

I've been looking at bash commands and scripts for the past 3 hours but haven't found it yet, and it seems like it should be an easy task to perform.

Ubuntu :: Network Card Powers Off And Doesn't Come Back Unless Rebooted

Dec 3, 2010

On one of my linux machines (Ubuntu 10.04, 64bit) misbehaves. Whether I restart the "networking" service or go through ifdown/ifup sequence the link disappears. I can see the router light goes off as if the cable is disconnected. The network card light goes dark as well. Everything looks like the device gets powered off and I can't get it back on.

Reboot fixes the problem though it doesn't quite makes sense that one needs to reboot in order to simply update IP configuration (e.g. change /etc/network/interfaces config from DHCP to static IP).

It is an hp compaq d220 MT.It looks good and feels good, well at least for a while since it keeps crashing. The screen starts to flicker, goes black, and the only way to get it up and running again is to press the on/off button until the system powers off and restart.

Ubuntu :: Keep The CPU Fan Spinning At 100% Constantly ?

I think I have found the problem to my Ubuntu laptop locking up, and it is most likely overheating. Is there any way to keep the CPU fan spinning at 100% constantly? I tried setting it up in the BIOS but it is an old laptop and I can't control it from there.

General :: How To Get CPU Fan To Stop Spinning When Idle

Aug 11, 2011

I have a PC which I built ~3 years ago which had been running smoothly and silently until recently. Now, the CPU fan likes to spin up to 1200-1500 RPM even when it's idle, which is rather annoying. I have not made any recent changes (software-wise or hardware-wise) to it.

The specs:
Motherboard: Gigabyte MA78GM-S2HP
CPU: AMD Athlon(tm) Dual Core Processor 4850e
Case: Antec Minuet 350 MicroATX
OS: Ubuntu 10.04, Linux 2.6.38-10-generic

I installed the lm-sensors and hddtemp packages (via apt-get) and configured them. Here's a typical output at steady-state, where the computer's been idle for a while and the fans have been spinning for the same while:

$ sensors
Adapter: PCI adapter
Core0 Temp: +29.0°C
Core0 Temp: +32.0°C
Core1 Temp: +27.0°C
Core1 Temp: +22.0°C
Adapter: ISA adapter .....
$ sudo hddtemp /dev/sda
/dev/sda: WDC WD5000AACS-00ZUB0: 35°C

These all seem fairly normal to me, so I'm perplexed as to why the fan continues to run at such a high RPM. What does the ALARM that's reported for in6 mean? Is it important? I've been playing around with the fancontrol daemon, trying to see if I could get better results than with the default fan management. Using the pwmconfig utility, I generated the following /etc/fancontrol file:

# Configuration file generated by pwmconfig, changes will be lost
DEVPATH=hwmon0=devices/pci0000:00/0000:00:18.3 hwmon1=devices/platform/it87.552
DEVNAME=hwmon0=k8temp hwmon1=it8718
FCTEMPS= hwmon1/device/pwm1=hwmon0/device/temp1_input
FCFANS= hwmon1/device/pwm1=hwmon1/device/fan1_input
MINTEMP= hwmon1/device/pwm1=35
MAXTEMP= hwmon1/device/pwm1=60
MINSTART= hwmon1/device/pwm1=180
MINSTOP= hwmon1/device/pwm1=100

This only sort of works—as soon as I enable the fancontrol daemon, the fan shuts off at first (good), but the temperatures of the 7 different sensors slowly rise, even when everything is idle. Eventually, when the Core0 Temp sensors goes past 35°, the fan comes back on, and then it alternates from being on and off at around 500-700 RPM, as the temperature goes back and forth across the boundary. It's certainly much more pleasant than 1200-1500 RPM, but it's still far from desirable.

Here's an example of the sensors output in that situation:
$ sensors
Adapter: PCI adapter
Core0 Temp: +36.0°C
Core0 Temp: +38.0°C
Core1 Temp: +34.0°C
Core1 Temp: +30.0°C
Adapter: ISA adapter .....
cpu0_vid: +1.100 V

I opened up the case, and the CPU heat sink felt warm but not excessively hot. I tried taking off the heat sink, cleaning off the thermal paste, putting on new thermal paste, and putting the heat sink back on, but that didn't seem to have much of an effect, if any. The two other heat sinks—one on the built-in AMD 780G graphics chipset and the other on the AMD SB700 southbridge—felt noticeably hotter than the CPU heat sink. So, my question is this: What should I do to get this computer back to the state where the fan is off when it's idle? Can I solve this with a smarter fancontrol configuration?

I cleaned out the heat sink and fan as best I could with compressed air (there wasn't a whole lot of dust, but I got rid of what I could), but still no dice. Rebooting into the BIOS configuration gives me the same results—the fan still runs at 1100-1200 RPM, and the system and CPU temperatures are reported as 40-44°C. Should I add another fan? The integrated GPU and the SB heatsinks felt significantly warmer to the tough than the CPU heatsink. The BIOS reports a system fan speed and NB fan speed of 0 rpm (since I don't have more than one fan).
