Hi Tomasz, Could you please checkout the 'pu' branch in e2fsprogs? You need to use pu branch of e2fsprogs because the patches of metadata checksum for e2fsprogs are in this branch. BTW, until 3.5 kernel, it seems that metadata checksum still has a bug. Here is a patch to fix this bug [1]. 1. http://www.spinics.net/lists/linux-ext4/msg32685.html Regards, Zheng -- To unsubscribe from this list: send the line "unsubscribe linux-ext4" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
