Hallo geehrte Forums-Community,
dies ist mein erster Forenpost hier, bitte um Gnade.
Ausgangssituation: Wir besitzen ein DS218+ mit 10 GB RAM und zwei 8TB WD Red das mit einem SHR (gespiegelt RAID1) konfiguriert ist. SMART Werte der HDDs sagen, dass diese im Schnellcheck ok sind. DSM ist ein 7.1.x
Letzte Woche ist es beim kopieren von Backups auf das NAS per NFS Protokoll zum Crash des BTRFS Filesystems gekommen und nun ist dieses nur noch READ-ONLY verfügbar, was natürlich nicht wirklich hilfreich ist im täglichen Betrieb. (Die Daten habe ich soweit es geht via SSH auf eine ext. angeschlossene 8TB USB Festplatte gesichert, bevor ich Reparaturversuche gestartet habe.)
Mittlerweile habe ich im DSM das Filesystem wieder schreibend eingebunden und versucht einen Data Scrubbing Job laufen zu lassen, um das Problem zu beheben. Dieser Job bricht leider wieder mit dem BTRFS Critical fehler ab und versetzt das Filesystem wieder in den Read Only Mode.
Im Netz habe ich noch den Befehl btrfs check --repair gefunden, habe mich aber noch nicht dazu durchgerungen diesen auszuführen, da
Ich habe auch schon ein Support Ticket bei Synology eröffnet und versucht dieses per Hotline zu eskalieren, leider habe ich nach über einer Woche immer noch kein Feedback erhalten, was sehr frustrierend ist.
Die Google-Suche war leider auch nicht sehr aufschlussreich für mich.
Vielen Dank im Voraus für eure Hilfe!
Anbei folgt der Auszug des Errors aus der DMESG des Synology Betriebssystems:

The very last resort tool is btrfs check --repair. It's reported to fix some issues some of the time, but with a good chance it will make others worse! You have been warned! Please see the btrfs check --repair wiki page.

- Was kann ich machen um das Filesystem zu reparieren, oder wie finde ich heraus welche Dateien nun corrupt sind im File System Tree? Eventuell kann man diesen leaf in dem Filesystem löschen und mit dem Filesystem weiter arbeiten?
- Hat hierzu schon einmal jemand Erfahrungen gesammelt und möchte diese an mich weitergeben?
- Könnte jemand das DMESG interpretieren und mir versuchen zu erklären, was schief gegangen ist?
- Kennt jemand einen Synology Partner der uns mit der Behebung dieses Problems professionell und gegen Bezahlung helfen könnte?
Vielen Dank im Voraus für eure Hilfe!
