Raspberry Pi meldet „Workqueue: events_freezable mmc_rescan“ (Virtual Memory/Swap-Problem)

Seit einiger Zeit ging mein Raspberry Pi 3 zwischen 4 und 5 Uhr morgens „offline“. Meine monit-Installationen meldeten mir dann jeweils, dass der SSH-Server auf dem RPi nicht mehr zu erreichen war (gestern bspw. traf die Meldung um 4:24 Uhr ein).

/var/log/syslog enthielt nachfolgende Meldungen. Die Nennung von mmc_get_card liess mich aufhorchen, weshalb ich eine neue Micro SD-Karte bestellte und die alte Karte auf die neue klonte. Leider liess sich damit das Problem nicht beheben.

Die Lösung fand ich via Pi freezing up 4 times a day – Workqueue: events_freezable mmc_rescan #1522 und via SWAP on Raspberry Pi / SD = AUTOCRASH und via Workqueue: events_freezable mmc_rescan crash with Raspbian kernel 4.14.79-v7+ hier: Linux Kernel panic issue: How to fix hung_task_timeout_secs and blocked for more than 120 seconds problem:

In /etc/sysctl.conf fügte ich folgende Zeilen ein:

...
vm.dirty_background_ratio = 5
vm.dirty_ratio = 10
...

Bis dahin waren folgende Werte aktiv:

# sysctl -a | grep -i dirty
vm.dirty_background_bytes = 0
vm.dirty_background_ratio = 10
vm.dirty_bytes = 0
vm.dirty_expire_centisecs = 3000
vm.dirty_ratio = 20
vm.dirty_writeback_centisecs = 500
vm.dirtytime_expire_seconds = 43200

Danach ein Reboot. Heute trat das Problem nicht auf, aber ich beobachte die Situation weiter.

setlocale: LC_ALL: cannot change locale

Seit ich mein MacBook Air mit M1-Chip und macOS Big Sur verwende, erhalte ich beim Login auf meinen Raspberry Pi 3 über SSH folgende Warnung zu Gesicht:

ssh dashboard
Linux DASHBOARD 5.10.17-v7+ #1403 SMP Mon Feb 22 11:29:51 GMT 2021 armv7l
Last login: Sat May  8 05:00:24 2021
-bash: warning: setlocale: LC_ALL: cannot change locale (en_US.UTF-8)

Ursache des Problems: en_US.UTF-8 ist in /etc/locale.gen kommentiert:

$ cat /etc/locale.gen | grep -v "^#"

en_GB.UTF-8 UTF-8

Somit die Datei öffnen, die Zeile mit en_US.UTF-8 suchen, ent-kommentieren, speichern und dann folgenden Befehl ausführen:

# locale-gen

Via: warning: setlocale: LC_ALL: cannot change locale

Beim nächsten Login erscheint die Fehlermeldung nicht mehr.

fr24feed 1.0.26-4 hat Probleme mit IPs, IPv6 und dem Web-Server

Kürzlich wurde auf meinem Pi24-Horchposten die neueste Version von fr24feed installiert: 1.0.26-4, Built on Sep 14 2020 08:32:40 (HEAD-bd20105.git/Linux/static_armel).

Umgehend reagierten meine monit Netzwerksensoren:

Connection failed Service pi24.domain.tld 

	Date:        Mon, 14 Sep 2020 19:03:03
	Action:      alert
	Host:        HOST
	Description: failed protocol test [HTTP] at [10.1.2.3]:8754 [TCP/IP] -- HTTP error: Regular expression doesn't match: No match

Your faithful employee,
Monit

Als ich auf das Web-Interface zugreifen wollte erschien auch tatsächlich folgende Fehlermeldung:

For security reasons the web interface is only availble from private class networks or after you have manually specified the bind-interface setting in /etc/fr24feed.ini

Please set it to bind-interface="0.0.0.0" to accept traffic from all interfaces or to the IP address of your preferred network interface!

For further assistance please contact support@fr24.com

Komisch! Nun gut, ich fügte also bind-interface="0.0.0.0" ans Ende der Datei /etc/fr24feed.ini und bootete den Pi24 neu. Das schaffte keine Abhilfe.

Selbst wenn ich auf dem Pi24 selber ein wget localhost:8754 respektive wget 127.0.0.1:8754 machte, erschien die Fehlermeldung.

Ich tüftelte noch eine Weile lang herum, und entdeckte dabei folgendes: Die neuste Version von fr24feed bindet sich aus irgendeinem Grund nur an IPv6:

$ netstat -tulpn
...
Proto Recv-Q Send-Q Local Address           Foreign Address         State       PID/Program name    
tcp6       0      :::8754                   :::*                    LISTEN      -                   
...

Ein Eintrag für denselben Port beginnend mit tcp fehlte.

Das CHANGELOG zeigt auf, dass die Kollegen aktuell an den Netzwerkfunktionalitäten von fr24feed rumbasteln und dabei bereits mehrere Male nachbessern mussten. Offenbar ist auch die neuste Version noch nicht ganz koscher.

Ein Blick in das Log von fr24feed zeigte folgende Einträge:

Komisch! Dem Problem konnte ich nicht auf den Grund gehen, wieso fr24feed die IP des Raspberry Pis nicht herausfinden konnte. strace könnte hier wohl weiterhelfen, doch das ging mir dann doch etwas zu weit. Schlussendlich hatte ich genug und entschied ich mich für ein Downgrade auf eine „last known good“ Version:

$ wget "https://repo.feed.flightradar24.com/rpi_binaries/fr24feed_1.0.25-3_armhf.deb" --no-check-certificate
# dpkg -i fr24feed_1.0.25-3_armhf.deb

Damit die neueste Version am nächsten Tag nicht erneut installiert wird, habe ich auch noch /etc/cron.d/fr24feed_updater angepasst:

47 9 1 * * root /usr/lib/fr24/fr24feed_updater.sh >> /var/log/fr24feed_update.log 2>&1

Hoffen wir, dass es bis zum 1. Oktober eine neue Version gibt, die mein Problem behebt.

Raspberry Pi zeigt ständig „Can’t update Chromium“ Overlay an

Mein Dashboard zu Hause läuft auf einem Raspberry Pi 3 mit Debian Buster 10.2. Der RPi lädt beim morgendlichen Neustart um Punkt 05:00 Uhr den Chromium-Browser, welcher die Web-Site mit dem Dashboard aufruft.

Seit ein paar Tagen zeigt Chromium oben rechts ein Layover mit folgender Meldung an:

Can’t update Chromium

Chromium couldn’t update to the latest version, so you’re missing out on new features and security fixes.

(da ich selber kein Photo des Dashboards angefertigt habe, verlinke ich hier auf einen Screenshot eines anderen Benutzers aus dem Internet)

Da Debian kein Update von Chromium anbietet, hilft ein apt-get upgrade chromium hier leider nicht weiter.

Das Symptom behebt man, indem man Chromium mit einem zusätzlichen Kommandozeilenargument startet — nachfolgend ein Auszug aus /home/pi/.config/lxsession/LXDE-pi/autostart:

...
@chromium-browser --no-default-browser-check --check-for-update-interval=604800 --disable-pinch --incognito --kiosk

Den Tipp mit --check-for-update-interval=604800 (Eintrag in der Liste der Kommandozeilenargumente) habe ich auf Stack Overflow in der Frage Disable “chrome is out of date” notification gefunden.

Da man als verantwortungsvoller SysAdmin entweder Debian unattended-upgrades respektive cron-apt (Vergleich) eingerichtet hat, oder sich zumindest automatisiert über Paket-Aktualisierungen informieren lässt, ist diese Symptombekämpfung vertretbar.

Die Entwickler von Chromium könnten sich meiner bescheidenen Meinung nach überlegen, ob es nicht besser wäre, nur dann eine Meldung anzuzeigen, wenn auch tatsächlich ein Update verfügbar ist. Denn die Meldung erscheint rein basierend auf dem Alter der Applikation, nicht basierend darauf, ob eine neue Version verfügbar ist:

there’s background process that checks the build date against the current time, and will start to complain if it’s more than 12 weeks ago.

smokeping auf einem Raspberry Pi installieren

Gestern habe ich einen verstaubten Raspberry Pi 1 aus meinem Endlager für obsolete IT-Hardware gerettet und ihn als arpwatch-Überwachungsstation aufgesetzt. Auf dem Gerät läuft folgendes Debian:

Linux raspberrypi 4.1.13+ #826 PREEMPT Fri Nov 13 20:13:22 GMT 2015 armv6l GNU/Linux

Etwas später stiess ich in Vorbereitung auf meinen Wechsel von upc cablecom zu Fiber7 auf den Artikel Fiber7 performance, in welchem Michael Stapelberg aufzeigt, wie sich die Latenz seiner Internetverbindung nach dem Wechsel von Swisscom auf Fiber7 verbessert hat.

Gedacht — getan: So etwas benötige ich natürlich auch, um meinen bevorstehenden Providerwechsel mit harten Fakten zu untermauern — wobei, ehrlich gesagt, ist mir die Latenz nicht so wichtig (bin kein Gamer), sondern viel mehr der vierfache Durchsatz und die symmetrische Down- und Upload-Geschwindigkeit zum selben Preis wie beim Kabelriesen.

Nichtsdestotrotz installierte ich mir also das Softwarepaket smokeping und seine Dependencies, wie das berühmte rrdtool aus dem Hause Oetiker:

# apt-get update
...
# apt-get upgrade
...
# apt-get install smokeping

Es wurde zwar alles nett installiert, doch konnte ich danach noch nicht auf die Web-Oberfläche unter http://localhost/smokeping/smokeping.cgi zugreifen. Unter einem x86-64 Debian war das nach der Installation automatisch möglich.

Zuerst wohl mal den Apache starten, dachte ich mir:

# /etc/init.d/apache2 start

Der Web-Server kam hoch, zeigte unter http://localhost/ die obligate Startseite an, doch unter dem Smokeping-Link kam ich statt der Smokeping-Oberfläche nur einen HTTP 403er zu Gesicht (mangels Screenshot und Text-Kopie mittels Auszug aus dem Apache error.log unter /var/log/apache2/):

...
[Wed Jan 20 22:52:59.338858 2016] [authz_core:error] [pid 2706:tid 3036673072] [client 10.0.1.101:56967] AH01630: client denied by server configuration: /usr/lib/cgi-bin/smokeping.cgi
...

Oookey … da ich smokeping auch noch auf einem „richtigen“ Linux-Server im Elternhaus laufen hatte, kopierte ich kurzerhand dessen VirtualHost-Konfiguration auf den Raspberry Pi (natürlich als Symlink auf conf-available):

# cat /etc/apache2/conf-enabled/smokeping.conf 
ScriptAlias /smokeping/smokeping.cgi /usr/lib/cgi-bin/smokeping.cgi
Alias /smokeping /usr/share/smokeping/www

<Directory "/usr/share/smokeping/www">
    Options FollowSymLinks
</Directory>

<Directory "/usr/lib/cgi-bin/">
    Options FollowSymLinks
    Require all granted
</Directory>

Noch ein …

# apache2ctl graceful

… und der 403er war weg. Das smokeping-GUI wurde aber weiterhin nicht angezeigt, sondern nur der Inhalt des CGI-Scripts im Klartext:

#!/bin/sh

exec /usr/share/smokeping/smokeping.cgi /etc/smokeping/config

Was zur Hölle … ? Doch auch diesem Fehlverhalten schaffte ich nach 15 Minuten googlen, Artikel lesen und pröbeln den Garaus: Ein simples

# a2enmod cgi

Via: Perl Apache : Perl script displayed as plain text

reichte aus, und plötzlich führte Apache das CGI-Script aus. Halleluja!

Raspberry Pi 2 einrichten (6/n): Automatisch in einen Web-Browser starten

Da ich meinen Raspberry Pi 2 dazu verwende, ein Dashboard anzuzeigen, soll der Taschencomputer nach einem Kaltstart automatisch aufstarten, sich mit dem Standardbenutzer in die graphische Oberfläche einloggen und danach ein Web-Browser-Fenster mit einer bestimmten URL öffnen. Dabei soll nur der Web-Site-Inhalt angezeigt werden, nicht aber die Fensteroberfläche des Window-Managers.

Automatischer Login

Auf der Kommandozeile öffnet man raspi-config und aktiviert dort die Option Enable Boot to Desktop/Scratch. Wichtig ist, dass man die Option mit den Cursortasten auswählt und danach mittels Tabulator auf „OK“ springt und dieses auch betätigt.

Quelle: RASPI-CONFIG

Automatischer Start des Web-Browsers mit einer bestimmten URL

Damit nun die gewünschte Web-Site angezeigt wird, muss man dem Betriebssystem nun noch sagen, dass bei jedem Login in die grafische Oberfläche ein entsprechender Befehl ausgeführt werden soll:

~/.config/lxsession/LXDE-pi/autostart

@xset s off
@xset -dpms
@xset s noblank

@unclutter -idle 1
# PROD
#@chromium-browser --incognito --kiosk http://dashboard.local/

# DEBUG
@chromium-browser --remote-debugging-port=4444 --show-fps-counter --incognito --kiosk http://dashboard.local/

Quelle: How to auto start chromium after boot on the Raspberry 2 (2015-01-31 debian wheezy)?

Ferner: How To Autostart Apps In Rasbian LXDE Desktop

Auch: Raspberry Pi Dashboard Kiosk

Wichtig: In vielen Anleitungen liest man, dass man die Datei /etc/xdg/lxsession/LXDE-pi/autostart (Raspberry Pi 2) respektive die Datei /etc/xdg/lxsession/LXDE/autostart (Raspberry Pi 1) mit den obigen Befehlen ergänzen soll. In meinem Fall hat das zu einer einstündigen Debugging-Session geführt, die erst mit folgendem Hinweis gelöst werden konnte:

Note: If both files are present, lxsession only executes the local file as of v0.4.9

Aus irgendeinem Grund war bei meiner Installation die Datei ~/.config/lxsession/LXDE-pi/autostart vorhanden, weshalb die Einträge in den generischen autostart-Dateien nie berücksichtigt wurden.

Quelle: LXDE

Mauszeiger ausblenden

Damit der Mauszeiger ausgeblendet wird, muss noch folgendes Paket installiert werden:

# apt-get install unclutter

Das Programm wird anschliessend beim Ausführen der Autostart-Datei ausgeführt.

Quelle: Step 16: Hiding the mouse pointer

Alternative: Window Manager umgehen und direkt in ein Browser-GUI starten

Dank an Simon Jenny für den Hinweis — leider bleibt der Bildschirm schwarz, diese Lösung funktioniert also derzeit nicht.

~/.xinitrc

xset -dpms &
xset s off &
unclutter -idle 1 &

exec chromium-browser \
--window-position=0,0 \
--window-size=1080,1920 \
--incognito \
--kiosk \
http://dashboard.local/

Folgende zusätzliche Parameter könnten ebenfalls hinzugefügt werden:

...
--no-first-run \
--disable \
--disable-translate \
--disable-infobars \
--disable-suggestions-service \
--disable-save-password-bubble \
--disk-cache-dir=/tmp/chromium/cache/ \
--user-data-dir=/tmp/chromium/user_data/ \
--show-fps-counter \
--remote-debugging-port=4444 \
...

/etc/rc.local

...
/usr/bin/xinit /home/pi/.xinitrc &
exit 0

Raspberry Pi 2 einrichten (4/n): Chromium installieren

Nachdem der Raspberry Pi 2 auf Raspbian Jessy läuft, können wir die neueste verfügbare Version des Chromium-Browsers herunterladen und installieren. Wir bedienen uns dazu der Repositories von Ubuntu und laden uns (Stand 22. Juni 2015) folgende zwei .deb-Pakete herunter:

Die Links zu den vorkompilierten Binaries finden sich auf den beiden Paket-Seiten rechts im Abschnitt „Downloadable Files“.

WICHTIG: Unter Raspberry Pi 1 läuft nur die unter Wheezy verfügbare Version 22 von Chromium. Neuere Versionen funktionieren unter diesem System nicht, weil die ARMv6-CPU des Raspberry Pi 1 keine hardwarebasierte Fliesskommaeinheit mitbringt. Das armhf-Paket von Ubuntu setzt diese CPU-Einheit aber leider voraus. Wer Chromium trotzdem auf dem nachfolgenden Weg installiert, erhält spätestens beim Start von Chromium folgende Fehlermeldung:

$ chromium-browser --version
Illegal instruction

Raspberry Pi 2 basiert glücklicherweise auf der ARMv7-Plattform und hat diese Einheit mit an Bord.

Sobald die Dateien im lokalen Dateisystem vorliegen, installiert man sie folgendermassen:

# dpkg -i chromium-browser_43.0.2357.81-0ubuntu0.15.04.1.1170_armhf.deb chromium-codecs-ffmpeg-extra_43.0.2357.81-0ubuntu0.15.04.1.1170_armhf.deb

Quelle: Installing Google Chromium on ARM devices with Flash plugin – solution

Ob die Installation erfolgreich war, zeigt folgender Befehl auf der Kommandozeile:

$ chromium-browser --version
Chromium 43.0.2357.81 Built on Ubuntu 15.04, running on Raspbian 8.0

Raspberry Pi 2 einrichten (7/n): Zeitzone und Uhrzeit einstellen

Mittels folgendem Befehl sollte man die Uhrzeit richtig stellen:

# dpkg-reconfigure tzdata

Ausserdem empfiehlt es sich, die Uhrzeit stündlich neu zu stellen:

# apt-get install ntpdate

/etc/crontab

...
* * * * *	root	ntpdate -s ch.pool.ntp.org

Raspberry Pi 2 einrichten (3/n): Von Raspbian Wheezy auf Jessie aktualisieren

Nachdem man SSH-Verbindungen herstellen kann, aktualisiert man zuerst einmal das System. Hierzu loggt man sich per SSH mit dem Benutzer pi ein und wechselt danach zum root-Benutzer:

$ sudo su -

Als nächstes aktualisiert man wie von Debian gewohnt die

# apt-get update

und installiert alle neuen Pakete:

# apt-get upgrade

Ist Wheezy auf dem neuesten Stand, wechseln wir das Repository in folgender Datei zu Jessie:

/etc/apt/sources.list

deb http://mirrordirector.raspbian.org/raspbian/ jessie main contrib non-free rpi

Nun führen wir erneut ein

# apt-get update

durch, um die Jessy-Paketliste herunterzuladen.

Jetzt startet die grosse Upgrade-Aktion:

# apt-get dist-upgrade

Nach einigen Stunden und allfälligen Dialogen sollte nach einem Reboot Raspbian Jessy auf dem System laufen.
