(Nu am lucrat cu acel tip de NAS.)
Compara primele blocuri din sdb si sdc ca sa vezi daca sint la fel.
Eu suspectez ca ai 'linear' intre sda+sdb si tot linear intre sdd+sdc. Si,
apoi, RAID 1 peste.
Ordinea pare ciudata, dar...
Nu stii cit spatiu era disponibil inainte de buseala?
Daca ma uit la size-ul raportat de LVM, pare ca e peste 500G+500G.
Ciudat.
