Esta versi\u00f3n es notable por la inclusi\u00f3n del soporte para el n\u00facleo Linux 6.6 y un intento de solucionar un problema que causa la corrupci\u00f3n de datos (reseteo de partes de bloques) en archivos despu\u00e9s de ser copiados.       <\/p>\n<p>Inicialmente se pens\u00f3 que el problema solo se manifestaba en la rama 2.2.x y era causado por un error en el mecanismo de clonaci\u00f3n de bloques incluido en OpenZFS 2.2.0, que permite crear una copia de un archivo o de parte de \u00e9l sin duplicar datos, utilizando en la segunda copia referencias a bloques de datos existentes del archivo original sin copiarlos realmente. En la versi\u00f3n OpenZFS 2.2.1, para bloquear el problema, el mecanismo de clonaci\u00f3n de bloques fue desactivado por defecto, y se agreg\u00f3 una configuraci\u00f3n zfs_bclone_enabled para restaurar el soporte de este modo.     <\/p>\n<p>M\u00e1s tarde, los desarrolladores informaron sobre la reproducci\u00f3n del problema tambi\u00e9n en configuraciones con la rama OpenZFS 2.1.x. No se confirmaron las suposiciones de que el problema se manifiesta en sistemas con versiones antiguas del paquete coreutils; se pudo reproducir el error en FreeBSD y en distribuciones de Linux con versiones recientes de coreutils 9.4.     <\/p>\n<p>La corrupci\u00f3n de archivos se manifiesta en situaciones bastante raras; por ejemplo, ejecutar en Gentoo el comando \u00abemerge -1 dev-lang\/go\u00bb conduce a la instalaci\u00f3n de herramientas para el lenguaje Go con archivos da\u00f1ados en el directorio \/usr\/lib\/go\/pkg\/tool\/linux_amd64\/compile. Se supone que el error comenz\u00f3 a manifestarse despu\u00e9s de establecer como predeterminado el par\u00e1metro \u00abzfs_dmu_offset_next_sync=1\u00bb en la versi\u00f3n openzfs 2.1.4. La fuente del error a\u00fan no se ha identificado. Como soluci\u00f3n recomendada para bloquear el error, se sugiere establecer en 0 el par\u00e1metro \u00ab\/sys\/module\/zfs\/parameters\/zfs_dmu_offset_next_sync\u00bb.<br \/>\n<br \/>Fuente: <a
