在f2fs.h中的数据结构如下所示 /** For superblock*/structf2fs_super_block{__le32magic;/* Magic Number */__le16major_ver;/* Major Version */__le16minor_ver;/* Minor Version */__le32log_sectorsize;/* log2 sector size in bytes */__le32log_sectors_per_block;/* log2 # of sectors...
通过深入研究mkfs.f2fs源码，我们得以深入了解F2FS文件系统的底层结构和初始化过程。首先，从早期commit和mkfs工具入手，虽然早期代码可能不够稳定，但便于理解论文中提及的关键特性。我们关注的重点在于格式化后F2FS磁盘的布局，通过调试mkfs.f2fs获取详细数据结构。磁盘布局由六个区域组成，具体结构可以通过调试程...
mkfs.f2fsis used to create a f2fs file system (usually in a disk partition).deviceis the special file corresponding to the device (e.g./dev/sdXX).sectorsis optionally given for specifing the filesystem size. The exit code returned bymkfs.f2fsis 0 on success and 1 on failure. ...
When trying to format a partition larger than 2GB I get an error "mkdosfs: lseek: Value too large for defined data type" With other busybox binaries it works fine. I presume that this is relevant: http://blog.scottt.tw/2009/07/mkdosfs-on...
