Dost\u0119pna jest wersja po\u015brednia projektu OpenZFS 2.2.1, rozwijaj\u0105cego implementacj\u0119 systemu plik\u00f3w ZFS dla Linux i FreeBSD. Wydanie to wyr\u00f3\u017cnia si\u0119 dodaniem wsparcia dla j\u0105dra Linux 6.6 oraz pr\u00f3b\u0105 naprawy problemu prowadz\u0105cego do uszkodzenia danych (zerowania cz\u0119\u015bci blok\u00f3w) w plikach po ich skopiowaniu. <\/p>\n
Pocz\u0105tkowo zak\u0142adano, \u017ce problem wyst\u0119puje tylko w ga\u0142\u0119zi 2.2.x i jest spowodowany b\u0142\u0119dem w w\u0142\u0105czonym mechanizmie klonowania blok\u00f3w w OpenZFS 2.2.0, kt\u00f3ry pozwala na utworzenie kopii pliku lub jego cz\u0119\u015bci bez duplikowania danych, wykorzystuj\u0105c w drugiej kopii odno\u015bniki do ju\u017c istniej\u0105cych blok\u00f3w danych pliku \u017ar\u00f3d\u0142owego bez ich faktycznego kopiowania. W wersji OpenZFS 2.2.1, aby zablokowa\u0107 problem, mechanizm klonowania blok\u00f3w zosta\u0142 domy\u015blnie wy\u0142\u0105czony, a dla przywr\u00f3cenia wsparcia tego trybu dodano opcj\u0119 zfs_bclone_enabled. <\/p>\n
P\u00f3\u017aniej deweloperzy potwierdzili odtworzenie problemu tak\u017ce w konfiguracjach z ga\u0142\u0119zi\u0105 OpenZFS 2.1.x. Nie potwierdzi\u0142y si\u0119 r\u00f3wnie\u017c przypuszczenia, \u017ce problem wyst\u0119puje w systemach z starszymi wydaniami pakietu coreutils \u2014 b\u0142\u0105d uda\u0142o si\u0119 odtworzy\u0107 w FreeBSD oraz w dystrybucjach Linuksa z najnowszym wydaniem coreutils 9.4. <\/p>\n
Uszkodzenie plik\u00f3w wyst\u0119puje w stosunkowo rzadkich okoliczno\u015bciach, na przyk\u0142ad, wykonanie w Gentoo polecenia \"emerge -1 dev-lang\/go\" prowadzi do zainstalowania narz\u0119dzi dla j\u0119zyka Go z uszkodzeniem plik\u00f3w w katalogu \/usr\/lib\/go\/pkg\/tool\/linux_amd64\/compile. Uwa\u017ca si\u0119, \u017ce b\u0142\u0105d zacz\u0105\u0142 si\u0119 ujawnia\u0107 po ustawieniu domy\u015blnego parametru \"zfs_dmu_offset_next_sync=1\" w wersji openzfs 2.1.4. \u0179r\u00f3d\u0142o b\u0142\u0119du nie zosta\u0142o jeszcze zidentyfikowane. Jako zalecane obej\u015bcie problemu zaproponowano ustawienie parametru \"\/sys\/module\/zfs\/parameters\/zfs_dmu_offset_next_sync\" na 0. \u0414\u043e\u0441\u0442\u0443\u043f\u0435\u043d
