Kutayika kwa data ya SSD mukamagwiritsa ntchito Linux kernel 5.1, LVM ndi dm-crypt

Pokonza kumasulidwa kwa kernel Linux 5.1.5 okhazikika vuto lili mu DM (Device Mapper) subsystem, yomwe zitha kuyambitsa ku kuwonongeka kwa data pama drive a SSD. Vuto linayamba kuoneka pambuyo pake kusintha, yowonjezeredwa ku kernel mu Januwale chaka chino, imakhudza nthambi ya 5.1 yokha ndipo nthawi zambiri imawonekera pamakina omwe ali ndi ma drive a Samsung SSD, omwe amagwiritsa ntchito kubisa deta pogwiritsa ntchito dm-crypt/LUKS pa chipangizo-mapper/LVM.

Chifukwa cha vuto ndi Kulemba mwaukali kwa midadada yomasulidwa kudzera pa FSTRIM (magawo ambiri adasindikizidwa nthawi imodzi, osaganizira malire a max_io_len_target_boundary). Mwa magawo omwe amapereka 5.1 kernel, cholakwikacho chakhazikitsidwa kale Fedora, koma akadali osakonzedwa mkati Archlinux (kukonza kulipo, koma kuli munthambi "yoyesa"). Njira yoletsera vutoli ndikuletsa ntchito ya fstrim.service/timer, kutchulanso fayilo yomwe ingathe kuchitika kwakanthawi, osapatula mbendera ya "kutaya" pazosankha zamtundu wa fstab, ndikuletsa "kulola-kutaya" mu LUKS kudzera pa dmsetup. .
