After investigation we found that the problem located in updated e2fsprogs.

From https://www.linuxfromscratch.org/lfs/view/stable/chapter08/e2fsprogs.html :

8.74.2.
          Configuring E2fsprogs
        
        
          /etc/mke2fs.conf contains the default
          value of various command line options of mke2fs. You may edit the file to
          make the default values suitable for your need. For example, some
          utilities (not in LFS or BLFS) cannot recognize a ext4 file system with metadata_csum_seed feature enabled. If you need such an utility, you may
          remove the feature from the default ext4 feature list with the command:
        
        sed 's/metadata_csum_seed,//' -i /etc/mke2fs.conf
        
          Read the man page mke2fs.conf(5) for
          details.
