/dev/sdb2: Directory inode 64, block #0, offset 0: directory has no checksum.
I think I should tell you how I solved this: It was a good advice to use debugfs, with it I could dump the directory block before and after running e2fsck and then I found out that it was rec_len in the last directory entry in a block that we did not initialize correctly, before it should extend to the end of the block but with cecksums we should subtract sizeof(struct ext4_dir_entry_tail) from it, thats why e2fsck did not look at the checksum even if it was there.
Thank you for youre help. Bo Branten
