Comment 5 for bug 864344

Well in the 1st run it does warn you that something odd happened:

WARNING: PROGRAMMING BUG IN E2FSCK!
 OR SOME BONEHEAD (YOU) IS CHECKING A MOUNTED (LIVE) FILESYSTEM.
inode_link_info[23300069] is 2, inode.i_links_count is 1. They should be the same!
Inode 23300069 ref count is 1, should be 1. Fix? yes

so I think after that warning all bets are off - and I can see from your df -h that your /dev/sdg1 isn't mounted,
so it does look like an e2fsck bug it got to that point.

Can I ask what did you do to your fs to get it into this state where the fsck started off with those
errors and can you describe the hardware.
