NAME<\/a> defrag.f2fs \u2212 relocate blocks in a given area to the specified region<\/p>\n defrag.f2fs<\/b> [ \u2212s<\/b> start block address<\/i> ] [ \u2212l<\/b> number of blocks<\/i> ] [ \u2212t<\/b> target block address<\/i> ] [ \u2212i<\/b> direction<\/i> ] [ \u2212d<\/b> debugging-level<\/i> ] device<\/i><\/p>\n defrag.f2fs<\/b><\/i> is used to move specified number of blocks starting from a given block address to the target block address with a direction. device<\/i> is the special file corresponding to the device (e.g. \/dev\/sdXX<\/i>).<\/p>\n For example, # defrag.f2fs -s 0x4000 -l 0x100 -t 0x10000 -i \/dev\/sdb1<\/p>\n This moves blocks between 0x4000 and 0x4100 to the left-hand area of 0x10000.<\/p>\n The exit code returned by defrag.f2fs<\/b> is 0 on success and -1 on failure.<\/p>\n \u2212s<\/b> start block address<\/i><\/p>\n Specify the starting block address.<\/p>\n \u2212l<\/b> number of blocks<\/i><\/p>\n Specifiy the number of blocks to move.<\/p>\n \u2212t<\/b> target block address<\/i><\/p>\n Specify the destination block address.<\/p>\n \u2212i<\/b> direction<\/i><\/p>\n Set the direction to left. If it is not set, the direction becomes right by default.<\/p>\n \u2212d<\/b> debug-level<\/i><\/p>\n Specify the level of debugging options. The default number is 0, which shows basic debugging messages.<\/p>\n This version of defrag.f2fs<\/b> has been written by Jaegeuk Kim
