Parcage intempestif des têtes de lecture du disque dur sur batterie

Ungars · Le 06/12/2009, à 21:33

Bonsoir.
Sur mon portable, lorsque je le mets sur batterie, la tête de lecture de mon disque dur se parc et se reparc plusieurs fois par minute (uniquement sur batterie) .

Je suis allé faire un tour sur la documentation, et j' ai testé différentes methodes, qui fonctionnait sous Gutsy, mais maintenant, sur le Heron, au mieux cela fonctionne quelques minutes, et je dois relancer les commandes proposées régulièrement. Ces dernières doivent être lancées en mode batterie, sinon elles sont inéfficaces. Sous Gutsy, mais également sur d' autres distributions, j' avais essayé entre autre de mettre au boot :

sudo hdparm -B 254 /dev

Cela fonctionnait sans problème, sur secteur ou batterie, mais pas avec la version 8.04

J' ai essayé avec le même résultat les commandes proposées, à savoir :

cmd='hdparm -B 254 /dev/sda';sudo $cmd && echo -e '#!/bin/sh\n'"$cmd" > /tmp/hdfix && sudo install /tmp/hdfix /etc/pm/power.d/00-hdparm.sh && sudo install /tmp/hdfix /etc/pm/sleep.d/00-hdparm.sh

Et :

sudo hdparm -B 254 /dev/sda && echo -e '#!/bin/sh\nhdparm -B 254 /dev/sda' > /tmp/99-hdd-spin-fix.sh && for i in start suspend resume; do sudo install /tmp/99-hdd-spin-fix.sh /etc/acpi/$i.d; done

Donc comme je le disais, la commande fonctionne que quelques minutes, et à condition de la lancer en mode batterie, après quelques minutes le parcage revient, et bien évidemment au reboot il faut recommencer.

J' essaye donc une troisième methode, la création d' un fichier nommé 99-hdd-spin-fix.sh dans lequel je mets :

 #!/bin/sh
hdparm -B 254 /dev/hda

Et que je copie dans :

sudo install 99-hdd-spin-fix.sh /etc/acpi/start.d/
sudo install 99-hdd-spin-fix.sh /etc/acpi/suspend.d/
sudo install 99-hdd-spin-fix.sh /etc/acpi/resume.d/

Et là apparament cela fonctionne, j' ai fait plusieurs essais, plus de parcage. Mais... Le problème, c' est mon disque dur qui n' arrête pas d' ecrire, une demie seconde toutes les trois secondes environ. Je ne pense pas que ça doit etre bien bon.

Donc j' aurais voulu avoir vos avis.

Merci à tous pour votre aide, bonne soirée !

Salut,

une idée comme une autre: en lisant la doc ça parle de S.M.A.R.T., tu as vérifié dans le bios que la fonction est bien active ?
Sinon concernant l'écriture, il s'agit peut-être des logs vois si tu peux les réduire avec le paquet laptop-mode-tools et le script qu'il inclus lm-syslog-setup (toujours d'après la doc).
A part ça, je laisse ma place à quelqu'un qui maitrise ce sujet.

ps: tu as essayé avec un autre kernel ? (vu là)

Ungars · Le 07/12/2009, à 22:22

Salut, merci pour le tuyau. Je vais voir pour ce que tu m' as dis ces prochains jours, pour le kernel, apparament les versions ultérieures à la mienne ont les mêmes problèmes que toi.
C' est peut etre l' histoire des logs qui me pose problème, tu as peut etre raison. Je vois ça dans la semaine et te tiens au courant.

Salut à tous.

Je reprends le problème... J' ai suivi pas à pas la doc présente sur le site concernant le laptomode tool. J' ai modifié les 2 fichiers :

/etc/default/acpi-support

# Switch to laptop-mode on battery power - off by default as it causes odd
# hangs on some machines
ENABLE_LAPTOP_MODE=true

Et :

/etc/laptop-mode/laptop-mode.conf

#
ENABLE_LAPTOP_MODE_ON_BATTERY=1


#
# Enable laptop mode when on AC power.
#

# When to enable data loss sensitive features
# -------------------------------------------
#
# When data loss sensitive features are disabled, laptop mode tools acts as if
# laptop mode were disabled, for those features only.
#
# Data loss sensitive features include:
# - laptop_mode (i.e., delayed writes)
# - hard drive write cache
#
# All of the options that follow can be set to 0 in order to prevent laptop
# mode tools from using them to stop data loss sensitive features. Use this
# when you have a battery that reports the wrong information, that confuses
# laptop mode tools.
#
# Disabling data loss sensitive features is ACPI-ONLY.
###############################################################################


#
# Disable all data loss sensitive features when the battery level (in % of the
# battery capacity) reaches this value.

###############################################################################
# Controlled hard drives and partitions
# -------------------------------------
#
# For spinning down your hard drives, laptop mode will remount file systems and
# adjust hard drive spindown timeouts. These parameters specify which
# devices and partitions are affected by laptop mode.
###############################################################################


#
# The drives that laptop mode controls.
# Separate them by a space, e.g. HD="/dev/hda /dev/hdb". The default is a
# wildcard, which will get you all your IDE and SCSI/SATA drives.
#
HD="/dev/[hs]d[abcdefgh]"


#
# The partitions (or mount points) that laptop mode controls.
# Separate the values by spaces. Use "auto" to indicate all partitions on drives
# listed in HD. You can add things to "auto", e.g. "auto /dev/hdc3". You can
# also specify mount points, e.g. "/mnt/data".
#
PARTITIONS="auto /dev/mapper/*"


#
# If this is enabled, laptop mode tools will assume that SCSI drives are
# really SATA drives that only _look_ like SCSI drives, and will use hdparm
# to control them. Set this to 0 if you have /dev/sd devices and you want
# laptop mode tools to use the "sdparm" command to control them.

###############################################################################
# Syslog configuration control
# ----------------------------
# 
# Syslog daemons have a tendency to sync their log files when entries are
# written to them. This causes disks to spin up, which is not very nice when
# you're trying to save power. The syslog.conf can be tweaked to *not* sync
# a given file, by prepending the log file name with a dash, like this:
#
# 	mail.*		-/var/log/mail/mail.log
#
# Using the following options, you can let laptop mode switch between
# different syslog configurations depending on whether you are working on
# battery or on AC power. To set this up, start by configuring these options
# for your syslog daemon, and then run lm-syslog-setup to create the various
# files. Then edit the laptop mode-specific syslog configuration files to
# remove the syncs only when laptop mode is active.
###############################################################################


#
# Should laptop mode tools control which syslog.conf should be used?
#

#
# Laptop mode tools controls syslog.conf by replacing /etc/syslog.conf (or
# whatever you specify in SYSLOG_CONF) by a link to the files configured here.
# NOTE: these files are NOT created by default, and if they do not
# exist this feature will not work. You can run the script

# X display settings
# ------------------
#
# Using these settings, you can let laptop mode tools control the X display
# standby timeouts.
#
# This requires that you have installed the "xset" utility. It is part of the
# X.org server distribution and included in the package xorg-server-utils.
#
# The X settings are not automatically applied on login, and this is
# impossible fix for the user, since laptop mode tools must operate as root.

# LCD brightness settings
# -----------------------
#
# Using these settings, you can make laptop mode tools automatically adjust
# your LCD's brightness settings. The settings are extremely simple -- they
# only allow for the execution of a command, nothing more. The reason for this
# is that LCD brightness settings are very different between laptop vendors.
#
# Suggestions for commands:
#
#  * If your system has the file "/proc/acpi/video/VID/LCD/brightness" (VID may
#    be VID1 or similar), use this file as BRIGHTNESS_OUTPUT, and use
#    the command "echo <value>". The possible values can be listed using the
#    command:
#
#       cat /proc/acpi/video/VID/LCD/brightness
#
#  * If you have a file /sys/class/backlight/.../brightness, then you can use
#    that file as BRIGHTNESS_OUTPUT, and the command "echo <value>".
#
#    As far as I understand it the values are between 0 and
#    the value contained in the file /sys/class/backlight/.../max_brightness.
#
#  * For Toshiba laptops, use the command "toshset" with the -lcd or -inten
#    command. Read the toshset(1) manual page for more information on the
#    parameters for this command. If you use this command, set
#    BRIGHTNESS_OUTPUT to "/dev/null".

Tu as essayé de limiter les accès au HDD du système de log voire la dernière optimisation indiqué sur la fin de la doc? mais honnêtement moi je ne sais plus (ou alors upgrader vers intrepid->jaunty->karmic voir si ça se calme et attendre le lynx si tu veux une LTS)
Sinon tu as quoi en résultats de

sudo smartctl -a `mount | grep '/ ' | cut -d' ' -f1 | sed -e 's#[0-9]##'` | egrep 'Cycle|Power'
