leidiges Thema "Volume abgestürzt" alle 6 Stunden

[funzel1607]

Moin,

ich habe eine DS918+, welche vor 2 Jahren schon mal das Problem mit 3TB WD Red hatte, dass das Volume immer wieder mal sporadisch abgestürzt ist.
Habe es damals zum Anlass genommen einfach auf 4TB zu wechseln. Nun habe ich das Problem erneut, dass immer wieder das Volume abstürzt.
Nach einem Reboot läuft alles wieder. Was mit dabei die vergangenen Tage aufgefallen ist, ist dass das Volume immer um die selben Zeiten abstürzt!

Ich erhalte die Mail dann immer um 00:13, 06:13, 12:13 oder 18:13 Uhr. Als wenn ein Task den Fehler triggern würde...
Ich habe schon alle Tasks, auch wenn zu dem Zeitpunkt augenscheinlich keiner laufen sollte, mal deaktiviert. Dennoch zerreißt es mir das Volume immer auf die Minute genau...

SMART habe ich schon alle vier Platten extended getestet, RAM und RAM-Slot schon getauscht (4GB original und 8GB Hylix) und via Synology Assistent getestet, alles ok.

Jemand noch eine Idee, welcher Task alle 6h läuft, der das triggern könnte? Habe schon nahezu alle Pakete gestoppt. Auch externes USB Backup abgestöpselt.
Versuche gerade ein letztes sauberes Backup via HyperBackup auf meine zweite Syno-Schachtel zu bringen, was aktuell immer abstürzt, da es >6h dauert...

PS: Wenn das Volume abstürzt erhalte ich plötzlich immer Mails der Surveillance Station, wenn eine Bewegung erkannt wird, was nicht so geconft ist und sonst auch nicht passiert

Danke für eure Ideen!

Ich habe mir nun live die /var/log/messages angeschaut und folgendes passiert exakt alle 6h

Was kann ich daraus ableiten?

Danke im Voraus!

Ich habe mittlerweile herausgefunden, dass es durch Backupjobs zu diesen Zeiten getriggert wird, die per NFS auf die Platten schreiben.
Warum es dabei das Volume zerreißt, weiß ich jedoch noch nicht.

Ich lasse nun die Datenträgerbereinigung laufen (RAID5 - Btrfs) und schaue mal, was er mir dann sagt.

Vielleicht ein sterbendes Netzteil?

Ich habe ein Full-Backup gemacht und bin auf Rat des Supports von Btfrs wieder auf ext4 gewechselt.
Seitdem ist Ruhe
