ich hoffe, dass ich hier richtig bin
Habe ein "kleines" Problem mit meinem root Server: SW Raid 1 über 2 SSDs: der Gute bootet nicht mehr, komme bei der Überprüfung / Fehlerbehebung von grub nicht weiter.. RAID schaut m.E. sauber aus..
Google hat mich nicht wirklich weiter gebracht.. möchte ungern den jetzigen Zustand verschlimmbessern.
Ein paar Infos vorab, rausgezogen über rescuesystem vom Hoster..
