Okwu ọnwụ SSD mgbe ị na-eji Linux kernel 5.1, LVM na dm-crypt

Na ntọhapụ mmezi nke kernel Linux 5.1.5 edoziri nsogbu dị na DM (Device Mapper) subsystem, nke nwere ike ịkpata maka mmebi data na draịva SSD. Nsogbu malitere ịpụta mgbe emechara gbanwee, agbakwunyere na kernel na Jenụwarị nke afọ a, na-emetụta naanị ngalaba 5.1 na n'ọtụtụ ikpe na-egosi na sistemụ nwere Samsung SSD draịva na-eji data izo ya ezo site na iji dm-crypt / LUKS n'elu ngwaọrụ-mapper / LVM.

Ihe kpatara nsogbu ahụ Ọ bụ Akara oke ike nke blocks tọhapụrụ site na FSTRIM (ọtụtụ ngalaba ka edobere akara n'otu oge, na-eburughị n'uche oke oke max_io_len_target_boundary).
