Hallo liebe Ubuntu Gemeinde.
Ich benötige dringende Hilfe zur Datenrettung von meinem Server.
Seit über 10 Jahren hat er mir treu gedient seit Fridl99 mir damals geholfen hat.
Ich habe regelmäsig alle updates ohne Probleme gemacht und nach dem letzten Update bootet er nicht mehr.
Ich kenn jetzt nur noch mit einem Live USB Stick booten.
Alle Versuche das OS neu zu installieren sind fehlgeschlagen mit der Meldung schwerwiegender Fehler!?
Es sind 4 Festplatten verbaut.
sda1,2,3 und sdb1,2,3 (1=boot; 2=swap; 3=LVM)
sdc1 uns sdd1 (alle LVM)

Kann mir bitte jemand helfen wie ich Festplatten gemountet bekomme um meine Daten zu retten?
Vielen Dank im Vorraus
