The final arguement in Step 2 is 1024 (ie 1024 blocks) while your file from Step 1 is only 512 blocks (count=512). Changing the last arguement of mke2fs to 512 worked for me.
(In reply to comment #0) > Step 2: mke2fs -q -F -o Linux -b 1024 -g 256 /tmp/virtual 1024 From mke2fs man page: -g blocks-per-group ... There is generally no reason the user to ever set this parameter, as the default is optimal for the filesystem....
