License tweak: LGPL v2.1 vs LGPL v2 The important part is b) Use a suitable shared library mechanism for linking with the Library. A suitable mechanism is one that (1) uses at run time a copy of the library already present on the user's computer system, rather than copying library functions into the executable, and (2) will operate properly with a modified version of the library, if the user installs one, as long as the modified version is interface-compatible with the version that the work was made with.

f2fs-tools: add fsck.f2fs and dump.f2fs fsck.f2fs checks file system consistency, but does not repair a broken file system yet. dump.f2fs shows the information of a specific inode and makes dump file of SSA and SIT. f2fs checks file system consistency as follows: o When data about used area and its metadata are identical, f2fs is considered consistent. To verify such consistency, we use three bitmaps: nat_area_bitmap, sit_area_bitmap, and main_area_bitmap. First, each bit in nat_area_bitmap corresponds to a nid in NAT. Second, each bit in sit_area_bitmap corresponds to a valid block in a segment. This bitmap is same to the total valid_map of f2fs_sit_entries in SIT. Last, each bit in main_area_bitmap corresponds to a block in main area except meta area. After a consistency check of each block, we set or clear the corresponding bit of each bitmap. From the root node, we start consistency check. The verified information varies according to block type. 1. NODE - Read information of node block from NAT - Check if block address is allocated using node info. - Check if the type of f2fs_summary related to nid in SSA is NODE. - Update the corresponding bit in nat_area_bitmap. - Update the corresponding bit in sit_area_bitmap. - Set the corresponding bit in main_area_bitmap to 1. - Then, read node block. According to its attribute, explore inode/direct node/indirect node/double indirect node recursively. - If it is an inode block, we also check its xattr and hard link. 2. DATA - Check if the type of f2fs_summary related to nid in SSA is DATA. - Set the corresponding bits of sit_area_bitmap and main_area_bitmap to visited - If it is a dentry block, traverse each dentries that may be regular file or directory. At this time, it will check inode block again. Finally, we verify whether - every nat_area_bitmap is visited - any unreachable hard link exists - values of sit_area_bitmap and main_area_bitmap are identical - total_valid_block_count/node_count/inode_count are correct Usage: o fsck.f2fs # fsck.f2fs /dev/sdx options: -d debug level [default:0] o dump.f2fs # dump.f2fs -i [ino] /dev/sdx # dump.f2fs -s 0~-1 /dev/sdx (SIT dump) # dump.f2fs -a 0~-1 /dev/sdx (SSA dump) options: -d debug level [default:0] -i inode no (hex) -s [SIT dump segno from #1~#2 (decimal), for all 0~-1] -a [SSA dump segno from #1~#2 (decimal), for all 0~-1] Note: To use dump.f2fs, please run make install or ln -s fsck.f2fs dump.f2fs Signed-off-by: Changman Lee <cm224.lee@samsung.com> Signed-off-by: Byoung Geun Kim <bgbg.kim@samsung.com> Signed-off-by: Jaegeuk Kim <jaegeuk.kim@samsung.com> | 12 年前 | |

defrag.f2fs: introduce defragmentation tool This tool tries to move the valid blocks ranging from blkaddr to blkaddr + len to targeted blkaddr with a direction like expand or shrink. The option includes: -d debug level [default:0] -s start block address [default: main_blkaddr] -l length [default:512 (2MB)] -t target block address [default: main_blkaddr + 2MB] -i set direction as shrink [default: expand] For example, # defrag.f2fs -s 0x100 -l 0x10 -t 0x4000 /dev/sdb1 This will move data blocks between 0x100 and 0x110 to the right side of 0x4000 space.

F2FS 格式化工具
若要使用 f2fs 文件系统，需通过本工具对存储分区进行格式化。否则，将无法挂载 f2fs 文件系统。
编译前准备
您需要安装以下软件包：
- libuuid-devel 或 uuid-dev
- autoconf
- libtool
- libselinux1-dev
初始编译设置
在进行初始编译前，需运行 autoconf/automake 工具：
./autogen.sh
编译方法
./configure make make install
交叉编译方法（例如，针对 ARM 架构）
-
在 mkfs/Makefile.am 中添加以下行：
mkfs_f2fs_LDFLAGS = -all-static -
在 fsck/Makefile.am 中添加以下行：
fsck_f2fs_LDFLAGS = -all-static -
然后执行：
LDFLAGS=--static ./configure
--host=arm-none-linux-gnueabi --target=arm-none-linux-gnueabi
make
默认运行方式
mkfs.f2fs -l [LABEL] $DEV
有关更多 mkfs 选项，请参阅手册页。
