Hallo liebe Community!
Ich habe ein Softwareraid mit mdadm erstellt und nun ca 1 Jahr laufen gehabt.(Ich glaube nie neugestartet) Es handelt sich um ein Raid10 und die Platten sind identisch (WD RED 3TB). Nach einem Kernelupdate heute morgen kann ich mein Raid nicht mehr starten. Das Raid war zum reboot intakt und nahezu Täglich wurden Daten geschrieben. Smartdaten sind bei allen Disks IO.
Hier die wichtigen Ausgaben.
Versuch des Zusammenbaus:
mdadm --assemble --verbose /dev/md0 /dev/sda1 /dev/sdb1 /dev/sdc1 /dev/sdd1 /dev/sdf1 /dev/sdg1 mdadm: looking for devices for /dev/md0 mdadm: /dev/sda1 is identified as a member of /dev/md0, slot 0. mdadm: /dev/sdb1 is identified as a member of /dev/md0, slot 1. mdadm: /dev/sdc1 is identified as a member of /dev/md0, slot 5. mdadm: /dev/sdd1 is identified as a member of /dev/md0, slot 2. mdadm: /dev/sdf1 is identified as a member of /dev/md0, slot 4. mdadm: /dev/sdg1 is identified as a member of /dev/md0, slot 3. mdadm: added /dev/sdb1 to /dev/md0 as 1 mdadm: added /dev/sdd1 to /dev/md0 as 2 mdadm: added /dev/sdg1 to /dev/md0 as 3 mdadm: failed to add /dev/sdf1 to /dev/md0: Invalid argument mdadm: failed to add /dev/sdc1 to /dev/md0: Invalid argument mdadm: added /dev/sda1 to /dev/md0 as 0 mdadm: /dev/md0 assembled from 4 drives - need all 6 to start it (use --run to insist).

Bevor ich jetzt mit tollen Tips wie "Überschreib mal den Superblock von Disk XY" loslege wollte ich mal hier fragen ob jemand eine Lösung bzw. das Problem kennt. Ich hatte mich für ein Raid10 entschieden um Datenverlust zu vermeiden. Aktuell stellt sich die Situation wohl so dar als wären meine Daten ohne Raid besser aufgehomen gewesen 😀 Tips verry Welcome
Danke und Gruß
