In that case, the filesystem will see the error and execute whatever the default behavior on error is, which is different from filesystem to filesystem, but in the past has commonly been to force the filesystem immediately into a read-only mode so no further damage can happen and attempts at repair can be made in rescue mode. -- To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
