Existe algum espaço livre nesta partição sda3?

Question

O espaço total de sda3 é 80,2 GiB (29,8 + 0,218 + 3,7 + 30 + 6,3 = 70,018) Eu não entendo onde está o resto 80.2 -70.018 = 10.182 GB

Answer 1

O seu PV tem 17926 extensões físicas grandes (com 4MiB PEs, que é 70,02 GiB), o que significa que não ocupa toda a extensão da partição.

Possivelmente, a partição foi ampliada depois que o PV foi criado. Você deve poder usar pvresize para aumentar o tamanho da partição.

BTW, vgs , lvs e pvs são bons comandos para mostrar rapidamente a alocação em VG / LV / PVs.

Veja também pvs --units B -o all | less -S para informações precisas e completas sobre PVs.
