Date: Fri, 5 Aug 2011 12:27:51 +0800 From: Robin Dong <hao.bigrat@...il.com> To: linux-ext4@...r.kernel.org Cc: Robin Dong <sanbai@...bao.com> Subject: [PATCH 2/2 bigalloc] e2fsprogs: use s_log_block_size to decide s_first_data_block in ext2fs_initialize From: Robin Dong <sanbai@...bao.com> After mke2fs with 1024 block size: #misc/mke2fs -m 0 -O ^resize_inode,extent,meta_bg,bigalloc -b 1024 /dev/sda kernel reports: [74687.352702] EXT4-fs (loop0): ext4_check_descriptors: Inode bitmap for group 0 not in group (block 524288)! [74687.355534] EXT4-fs (loop0): group descriptors corrupted! when mount /dev/sda. The reason is mke2fs set s_first_data_block to 0 by mistake just because s_log_cluster_size is 4 when s_log_block_size==0. This patch is based on "next" branch of e2fsprogs.
