Hi, 
  
  Thank you for patch.
 I have try to mount as you propose, but receive following errors:
/sbin/mount.nilfs2 -r -o cp=30778 /dev/cciss/c0d1p1 /mnt/

NILFS: latest checkpoint=30778
NILFS: The specified checkpoint is not a snapshot (checkpoint number=30778).
NILFS: corrupt root inode.


If I try to mount older snapshot 
/sbin/mount.nilfs2 -r -o cp=27252 /dev/cciss/c0d1p1 /mnt/

then 

NILFS: latest checkpoint=30778
NILFS: corrupt root inode.

If try to convert 30778 to snapshot I get
chcp: /dev/cciss/c0d1p1: cannot open NILFS
 
Thank you.

Yuri.
