--- Comment #1 from Qinghua Jin (qhjin_dev@....com) ---
It seems that the tmp38.img is corrupt. Could you please send a correct one?

$ e2fsck tmp38.img 
e2fsck 1.45.7 (28-Jan-2021)
ext2fs_open2: The ext2 superblock is corrupt
e2fsck: Superblock invalid, trying backup blocks...
tmp38.img contains a file system with errors, check forced.
Resize inode not valid.  Recreate<y>? yes
Pass 1: Checking inodes, blocks, and sizes
Root inode has dtime set (probably due to old mke2fs).  Fix<y>? yes
Inode 13 has an invalid extent
        (logical block 0, invalid physical block 8332801, len 1)
Clear<y>? yes
Inode 13 has an invalid extent
        (logical block 0, invalid physical block 64344, len 1)
Clear<y>? yes


Thanks,
Qinghua Jin
