Det finns en f\u00f6rhandsversion av projektet OpenZFS 2.2.1, vilket utvecklar filsystemet ZFS f\u00f6r Linux och FreeBSD. Utg\u00e5van k\u00e4nnetecknas av till\u00e4gget av st\u00f6d f\u00f6r Linux-k\u00e4rnan 6.6 och ett f\u00f6rs\u00f6k att \u00e5tg\u00e4rda ett problem som leder till dataskador (nollst\u00e4llning av delar av block) i filer efter att de kopierats. <\/p>\n
Ursprungligen ans\u00e5gs problemet endast f\u00f6rekomma i version 2.2.x och orsakades av ett fel i OpenZFS 2.2.0:s blockkloningmekanism, som till\u00e5ter att skapa en kopia av en fil eller dess delar utan att duplicera data, genom att anv\u00e4nda referenser till redan existerande datablok fr\u00e5n den ursprungliga filen utan faktisk kopiering. I version OpenZFS 2.2.1 har blockkloningmekanismen st\u00e4ngts av som standard f\u00f6r att blockera problemet, och en inst\u00e4llning f\u00f6r att \u00e5terinf\u00f6ra st\u00f6d f\u00f6r detta l\u00e4ge har lagts till: zfs_bclone_enabled. <\/p>\n
Senare meddelade utvecklarna att de kunde \u00e5terge problemet \u00e4ven i konfigurationer med OpenZFS 2.1.x-grenen. Antagandena om att problemet skulle upptr\u00e4da p\u00e5 system med gamla versioner av coreutils-paketet har inte bekr\u00e4ftats \u2014 felet kunde \u00e5terges p\u00e5 FreeBSD och i Linux-distributioner med den senaste versionen av coreutils 9.4. <\/p>\n
Filskador upptr\u00e4der vid en tillr\u00e4ckligt s\u00e4llsynt samverkan av omst\u00e4ndigheter, exempelvis ger utf\u00f6rande av kommandot \u00abemerge -1 dev-lang\/go\u00bb i Gentoo upphov till installation av verktyg f\u00f6r spr\u00e5ket Go med skadade filer i katalogen \/usr\/lib\/go\/pkg\/tool\/linux_amd64\/compile. Det antas att felet b\u00f6rjade upptr\u00e4da efter att standardinst\u00e4llningen f\u00f6r parametern \u00abzfs_dmu_offset_next_sync=1\u00bb inf\u00f6rdes i version openzfs 2.1.4. K\u00e4llan till felet har \u00e4nnu inte identifierats. Som en rekommenderad l\u00f6sning f\u00f6r att blockera felet f\u00f6resl\u00e5s att s\u00e4tta parametern \u00ab\/sys\/module\/zfs\/parameters\/zfs_dmu_offset_next_sync\u00bb till 0.
