Ich war so doof und habe die Backup Datei auf dem LVM gespeichert, unter dem unter anderem das betreffende Raid liegt.
( https://forum.ubuntuusers.de/topic/daten-von-einer-lvm-partition-wiederherstellen/ )
Nun komme ich nicht mehr ran und suche mit photorec diese doofe Datei.
Kann mir jemand mal den inhalt so einer Datei schicken, damit ich weiß nach was ich mit find suchen muss?

wenn du danach ein grow gemacht hast, ist das mdadm Backup ohnehin ziemlich nutzlos das ist jetzt dein zweiter? Thread zu deinem Problem ohne Inhaltsangabe was bekommst du denn für mdadm --examine /dev/sd*? und cat /proc/mdstat? |

Allem Anschein nach ist dein Reshape da direkt gegen eine Wand gefahren. dmesg vom Zusammenbauen? Was passiert nach --stop, --assemble, ggf. --grow --continue? |

Hattest du denn ursprünglich ein Backup-File angegeben? ...falls ja, hast du das noch? Ansonsten evtl. auch noch --assemble --update=revert-reshape oder gar --update=revert-reshape-nobackup |

Darum geht es ja, die habe ich (pure Dummheit) auf dem LVM gespeichert worunter unter anderem die beiden Raids liegen. No file found, filesystem may be damaged.
Evtl kann man das "reparieren" und ihn denken lassen, dass es ein ext4 ist? |

Ahhh, mea culpa, kleines Mißverständnis. Ich dachte du hättest ein Backup von den Metadaten gemacht.
Rohdaten... mit photorec wirst da nicht glücklich. Mit Testdisk kommst bei RAID 5 auch nicht weiter, das RAID muss laufen. Wenn du Testdisk versuchen läßt da irgendwas zu reparieren machst du es dir erst recht kaputt.
Die Reshape Pos'n ist auf 0 (bzw. auf hinterster Radkante weil das beim Shrink rückwärts läuft). Also eigentlich™ sollte da nix passieren weil der Reshape noch gar nicht wirklich begonnen hat. Du kannst mit Overlay experimentieren: https://raid.wiki.kernel.org/index.php/Recovering_a_failed_software_RAID#Making_the_harddisks_read-only_using_an_overlay_file Aber dann musst du beim assemble die Devices selber angeben da rein nach UUID kein Unterschied zwischen echtem Device und Overlay besteht. |

Kurzes Feedback:
Das Revert hat geklappt und die allerwichtigsten Daten scheinen wieder da zu sein. (Deren Sicherungskonzept werde ich demnächst auch nochmal überarbeiten...) mount: /media/daten-raid/Backup: special device /dev/Raid/Backup does not exist. mount: /media/daten-raid/Spiele: special device /dev/Raid/Spiele does not exist.
Aber es kann sein, dass die beim Reshape kaputt gegangen war, weil ich da scheinbar was falsch gemacht habe. |
