Jaegeuk Kim 2c1ebe237a 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.
