(Note the date.) Do you see it in your repository? Or are you using an unusual inode size? (e.g., not 256 bytes, or 16 inodes per block). - Ted commit 06c35f935a7adadceb9ee326b3231f952f6ad203 Merge: 480a3b1 96cc54a Author: Colin Cross <ccross@xxxxxxxxxxx> Date: Sat Apr 30 19:08:09 2011 -0700 Merge "Make inodes per group a multiple of inodes per block" diff --cc ext4_utils/make_ext4fs.c index c9fd992,e37d617..22c9424 --- a/ext4_utils/make_ext4fs.c +++ b/ext4_utils/make_ext4fs.c @@@ -214,26 -215,10 +214,27 @@@ static u32 compute_inodes_per_group( { u32 blocks = DIV_ROUND_UP(info.len, info.block_size); u32 block_groups = DIV_ROUND_UP(blocks, info.blocks_per_group); - return DIV_ROUND_UP(info.inodes, block_groups); + u32 inodes = DIV_ROUND_UP(info.inodes, block_groups); + return ALIGN(inodes, (info.block_size / info.inode_size)); } +static u32 compute_bg_desc_reserve_blocks() +{ + u32 blocks = DIV_ROUND_UP(info.len, info.block_size); + u32 block_groups = DIV_ROUND_UP(blocks, info.blocks_per_group); + u32 bg_desc_blocks = DIV_ROUND_UP(block_groups * sizeof(struct ext2_group_desc), + info.block_size); + + u32 bg_desc_reserve_blocks = + DIV_ROUND_UP(block_groups * 1024 * sizeof(struct ext2_group_desc), + info.block_size) - bg_desc_blocks; + + if (bg_desc_reserve_blocks > info.block_size / sizeof(u32)) + bg_desc_reserve_blocks = info.block_size / sizeof(u32); + + return bg_desc_reserve_blocks; +} + void reset_ext4fs_info() { // Reset all the global data structures used by make_ext4fs so it // can be called again.
