Den mellemliggende udgave af OpenZFS 2.2.1, der udvikler implementeringen af filsystemet ZFS til Linux og FreeBSD, er tilg\u00e6ngelig. Udgivelsen er bem\u00e6rkelsesv\u00e6rdig ved tilf\u00f8jelsen af st\u00f8tte til Linux-kernen 6.6 og et fors\u00f8g p\u00e5 at l\u00f8se et problem, der f\u00f8rer til datakorruption (nulstilling af dele af blokke) i filer efter de er kopieret. <\/p>\n
Det blev oprindeligt antaget, at problemet kun optr\u00e5dte i 2.2.x-grenen og blev for\u00e5rsaget af en fejl i den blokkloningsmekanisme, der er inkluderet i OpenZFS 2.2.0, som g\u00f8r det muligt at oprette en kopi af en fil eller en del af den uden at duplikere data, ved at bruge henvisninger til allerede eksisterende data blokke i den originale fil uden faktisk at kopiere dem. I versionen OpenZFS 2.2.1 blev blokkloningsmekanismen som standard deaktiveret for at blokere problemet, og for at genoprette underst\u00f8ttelsen af denne tilstand blev indstillingen zfs_bclone_enabled tilf\u00f8jet. <\/p>\n
Senere meddelte udviklerne, at de havde genskabt problemet i konfigurationer med OpenZFS 2.1.x-grenen. Antagelserne om, at problemet kun optr\u00e6der p\u00e5 systemer med gamle versioner af coreutils-pakken, blev ikke bekr\u00e6ftet \u2013 fejlen kunne genskabes i FreeBSD og i Linux-distributioner med den seneste version af coreutils 9.4. <\/p>\n
Filkorruption optr\u00e6der under ret sj\u00e6ldne omst\u00e6ndigheder, for eksempel n\u00e5r man k\u00f8rer kommandoen \u00abemerge -1 dev-lang\/go\u00bb i Gentoo, som medf\u00f8rer installation af v\u00e6rkt\u00f8jer til Go-sproget med korruptede filer i kataloget \/usr\/lib\/go\/pkg\/tool\/linux_amd64\/compile. Det antages, at fejlen begyndte at optr\u00e6de, efter at parameteren \u00abzfs_dmu_offset_next_sync=1\u00bb blev indstillet som standard i version openzfs 2.1.4. Kilden til fejlen er endnu ikke identificeret. Som en anbefalet workaround til at blokere fejlen foresl\u00e5s det at s\u00e6tte parameteren \u00ab\/sys\/module\/zfs\/parameters\/zfs_dmu_offset_next_sync\u00bb til 0.
