Inkinga yokulahleka kwedatha ye-SSD uma usebenzisa i-Linux kernel 5.1, LVM ne-dm-crypt

Ekukhululweni kokugcinwa kwe-kernel Linux 5.1.5 kulungisiwe inkinga ikusistimu engaphansi ye-DM (Device Mapper), yona kungase kubangele ekonakaleni kwedatha kumadrayivu e-SSD. Inkinga yaqala ukuvela ngemuva shintsha, engezwe ku-kernel ngoJanuwari walo nyaka, ithinta kuphela igatsha le-5.1 futhi iningi lamacala livela ezinhlelweni ezinamadrayivu e-Samsung SSD, asebenzisa ukubethela kwedatha kusetshenziswa i-dm-crypt/LUKS phezu kwedivayisi-mapper/LVM.

Imbangela yenkinga kuyinto Ukumaka okunamandla kakhulu kwamabhulokhi akhululiwe nge-FSTRIM (imikhakha eminingi kakhulu imakwe ngesikhathi, ngaphandle kokucabangela umkhawulo omkhulu we-max_io_len_target_boundary). Ekusabalazweni okunikeza i-5.1 kernel, iphutha selivele lilungisiwe Fedora, kodwa kusalokhu kungalungiswanga I-ArchLinux (ukulungisa kuyatholakala, kodwa okwamanje kusegatsheni “lokuhlola”). Indlela yokusebenza yokuvimba inkinga ukukhubaza insiza ye-fstrim.service/timer, ukuqamba kabusha ifayela le-fstrim elisebenzisekayo, ungafaki ifulegi elithi "lahla" ezinkethweni zokukhweza ku-fstab, futhi ukhubaze imodi "yokuvumela-lahla" ku-LUKS nge-dmsetup. .
