Hi
ich schon wieder und befürchte gleiches Problem.

Haben den Raspberry inkl. IOBroker vor 14 Tagen nochmal komplett neu installiert und seitdem lief er stabil.

Heute Nachmittag den IObroker gestopt, aktualisiert und wieder gestartet.
Gerade bekam ich die Info dass er sich wieder aufgehangen hat. Diesmal, dank Eurer Warnungen, habe ich nicht den Stecker am RPI gezogen sondern warte auf Euer Feedback. Der IObroker ist nicht erreichbar, die SSH Verbindung via Putty wird abgebrochen. Einzig der Ping Befehl zum RPI ist noch erfolgreich.

Was mache ich nun richtig um den IObroker zu retten?

Vielen Dank vorab!

Sollte die SSD nicht das Problem sein

Die SSD selber sowieso nicht!

Das Dateisystem auf der SSD ist hin

Auf Verdacht Hardware tauschen, da würde ich der Sache noch eine Chance bis zur nächsten Detonation geben wollen.

dann solltest du aber unbedingt die Platte neu formatieren.
Denn die letzten Einschläge haben bereits einige Versorgungsleitungen zerstört, von denen du nur keine Kenntnis hast, welche das sind und welche Folgen das haben wird.

und ich wieder so einen Zustand "erleide"

diese Meldung kommt nicht mehr wieder (zumindest nicht bei den schon bestehenden Fehlern).
aber dein System ist trotzdem defekt.

du weisst nur nicht wu, und wann diese Zeitbombe zuschlägt

Ok, das hätte dann aber auch zur Folge, dass Dein ursprüngliches Problem (Speicher läuft voll) immer noch besteht. Nur hast dann mal ein System bei dem den Fehler suchen kannst und da tippe ich auf ne Schleife in einem Script.

müßte bei einem Reboot jetzt diese Meldung dann im Log weg sein?

da habe ich keine Ahnung von - ist Gebiet von @Thomas-Braun

@pete0815 sagte in IOBroker "stürtzt ab" warum?:

Ob mir das jetzt soviel hilft ist die Frage

wenn es Dateileichen gibt/gab, kann es sein, dass wichtige Dateien (Verweise dahin) für das System nicht mehr existieren.
Einfach damit zufrieden zu sein den Verweis zu einer fehlenden Datei zu löschen nennt man Vogel-Strauß-Politik.

Nur weil man den Hinweis löscht, kommt die Datei nicht wieder

Wenn ich es richtig verstehe, stehen dort ja diese orphan inodes als deleted und recovery complete drin. Sollte die SSD nicht das Problem sein, müßte bei einem Reboot jetzt diese Meldung dann im Log weg sein? Ob mir das jetzt soviel hilft ist die Frage, aber ich vermute dadurch schon mal keine neuen Fehler von gestern bis heute nachvollziehen zu können.

@homoran sagte: tac => letzter Eintrag oben

Danke, wieder was gelernt

Das muss ich mir einrahmen!!

Danke, wieder was gelernt

Der Befehl lautet cat (nicht tac).

die schreibweise ändert die Sortierungsrichtung
cat => ältester Eintrag oben
tac => letzter Eintrag oben

Der Befehl lautet cat (nicht tac).

Die Meldung bleibt leer bei mir in der Konsole

ich sagte ja, dass das jetzt nur den aktuellen status bringt. Nicht das was vor dem "reboot" war

tac /var/log/kern.log | grep -i under

Die Meldung bleibt leer bei mir in der Konsole. Öffne ich die log Datei manuell. steht Folgendes drin:

Eine Suche nach voltage oder under war erfolglos.

was ergibt : tac /var/log/kern.log | grep -i under ?
ist jetzt nach Neustart natürlich nicht unbedingt aussagekräftig

@pete0815 sagte in IOBroker "stürtzt ab" warum?:

Am Port vom PI

dann hast du wahrscheinlich ein Spannungsversorguungsproblem.
das RPi-Netzteil ist nicht gedacht zusätzliche Geräte zu versorgen.

Such mal nach under-voltage in den logs

EDIT:

@pete0815 sagte in IOBroker "stürtzt ab" warum?:

daneben funkt eint zigbee stick auf 2,4GHz.

auch an USB und darüber mit Strom versorgt?

Der hängt am USB2 Anschluß auch über den PI versorgt. Das waren dann aber aller Verbraucher am PI.

aus den system logs wie @Thomas-Braun sagt werde ich nicht schlau. Die sind "übervoll" mit den influxdB einträgen und regelmäßig tauchen die 3 Meldungen auf. CPU Freq kommt wohl vom RPI2 Adapter wo dies nicht auf einem RPI4 funktioniert. Wifi und BT ist bei mir deaktiviert daher wohl die Meldungen. Andere Meldungen sehe ich gar nicht. Eine Suche nach voltage oder under war erfolglos.
