Umba wokulahleka kwedatha ye-SSD xa usebenzisa i-Linux kernel 5.1, i-LVM kunye ne-dm-crypt

Kukhupho lokugcinwa kwekernel Linux 5.1.5 ilungisiwe ingxaki ikwi-DM (Device Mapper) indlela esezantsi, leyo inokubangela kurhwaphilizo lwedatha kwi-SSD drives. Ingxaki yaqala ukuvela emva utshintsho, eyongezwe kwi-kernel ngoJanuwari walo nyaka, ichaphazela kuphela isebe le-5.1 kwaye kuninzi lwamatyala avela kwiinkqubo ezine-Samsung SSD drives ezisebenzisa ukubethelwa kwedatha usebenzisa i-dm-crypt/LUKS phezu kwesixhobo-mapper/LVM.

Unobangela wengxaki kuyinto Ukumakishwa okundlongondlongo kakhulu kweebhloko ezikhululekileyo nge-FSTRIM (amacandelo amaninzi kakhulu aphawulwe ngexesha, ngaphandle kokuthathela ingqalelo max_io_len_target_boundary limit). Kwizabelo ezinikezela nge-5.1 kernel, impazamo sele ilungisiwe Fedora, kodwa ihleli ingalungiswanga Archlinux (ulungiso luyafumaneka, kodwa ngoku lukwisebe “lovavanyo”). Umsebenzi wokuthintela ingxaki kukuvala inkonzo ye-fstrim.service/timer, unike igama kwakhona okwexeshana ifayile ephunyezwayo ye-fstrim, ungabandakanyi iflegi "yokulahla" kwiinketho zokunyuka kwi-fstab, kwaye ukhubaze indlela "yokuvumela-ukulahla" kwi-LUKS nge-dmsetup. .
