Kent Overstreet, desarrollador del sistema de archivos Bcachefs, ha propuesto parches que permiten al n\u00facleo de Linux trabajar con el sistema de archivos Bcachefs incluso despu\u00e9s de da\u00f1ar una parte significativa de los metadatos, reconstruyendo los \u00e1rboles B da\u00f1ados seg\u00fan los metadatos de las estructuras de inode y dirent. Los cambios han sido aceptados por Linus Torvalds y est\u00e1n incluidos en la actualizaci\u00f3n de prueba del n\u00facleo 6.9-rc3 de hoy. <\/p>\n

Los cambios permiten el montaje de sistemas de archivos da\u00f1ados y proporcionan acceso a todos o casi todos los datos en el sistema de archivos afectados por un error reciente que llevaba a la destrucci\u00f3n del sistema de archivos. El error se manifestaba cuando, tras una actualizaci\u00f3n de herramientas, se intentaba pero no se lograba completar la actualizaci\u00f3n de las estructuras del sistema de archivos, despu\u00e9s de lo cual el n\u00facleo con la antigua implementaci\u00f3n de Bcachefs intentaba degradar la versi\u00f3n de las estructuras, ignorando la actualizaci\u00f3n incompleta. Esta situaci\u00f3n llevaba a entrar en el 'modo de cerebro dividido', donde ninguna de las operaciones puede completarse y las estructuras b-tree del sistema de archivos ya no son consistentes con el contenido real. <\/p>\n

El parche mencionado permite continuar la operaci\u00f3n incluso en tales casos. Entre las limitaciones de la tecnolog\u00eda se menciona que, en presencia de instant\u00e1neas, el \u00e1rbol B de las instant\u00e1neas debe estar presente y ser funcional.
