Hi,
Did you get to the bottom of this?
We are having exactly the same problem with our lustre-1.6.6 (rhel4) file

still are seeing the same errors
"ASSERTION(old_inode->i_state & I_FREEING)" is the infamous bug17485. You will
need to run lfsck to fix it.

Hello Wojciech,
bug 17485 has patch, that has landed in 1.8 to prevent that duplicate
references to OST objects come up after MDS fail over. But if you create
duplicate entries yourself, it won't help of course. Bug 20412 has such a
valid use case for duplicate MDT files and also lots of patche
