sudo dmesg -T | grep -i ext4

@thomas-braun

Nach 5 minuten immer noch kweine antwort

[Thomas Braun]

@iklaus

Laufen lassen...
Und bitte keine Screenshots aus Konsolistan.

[iKlaus]

@thomas-braun dauert das immer soooooo lange steht immer noch und kein Ergebnis

[Thomas Braun]

@iklaus

Normalerweise nicht.
Deutet aber auch auf ein Hardware/Kernel-nahes Problem hin.

[iKlaus]

@thomas-braun das heisst kaputto :( ?

[Thomas Braun]

@iklaus

sudo dmesg

spuckt was aus?
Kann lang sein, vermutlich reichen aber die letzen 20-30 Zeilen.

[Thomas Braun]

@iklaus

Hier dauert das übrigens nur Sekundenbruchtteile:

Kurz darauf ist die SD-Karte abgeraucht.
Höchste Eisenbahn da was frisches zu installieren, Backup mit intakten Daten einspielen.

[iKlaus]

@thomas-braun ok das heisst neu machen alles !

Das kann ich aber erst nächstes Wochenende machen bin Fernfahrer darf um 4 Uhr los fahren und bin dann erst Wochenende wieder da !

Bräuchte dann noch mal hilfe wegen backup

Danke dir erst einmal !

Werde den Rechner aus machen geht so oder so nichts in mom!

Habe ja noch einen mini PC hier stehen !

[crunchip]

@thomas-braun sagte in ioBroker nichts geht mehr:

sudo apt install redis

verstehe ich aber nicht warum er redis installieren soll, wenn doch jsonl verwendet wird.
es steht zwar

@iklaus sagte in ioBroker nichts geht mehr:

Error: States DB is not allowed to start in the current Multihost environment
at Redis.<anonymous> (/opt/iobroker/node_modules/@iobroker/db-states-redis/lib/states/statesInRedisClient.js:579:23)
at processTicksAndRejections (node:internal/process/task_queues:96:5)

aber der js-controller verwendet doch die die interne redis Datenbank, zu sehen an den Ports,
das hat doch nichts mit redis in dem Sinn zu tun, redis installiert man doch nur wenn man redis anstatt jsonl verwendet

@iklaus sagte in ioBroker nichts geht mehr:

redis läuft auf Port 6379, zu sehen, jetzt nach der Installation
