Yes, I read the entire document multiple times. I even found some

of aggrinode self)

Thanks, but looking into the iag:

http://magnifier.sourceforge.net/tmp/jfs_inode_alloc_map_start.png

Or more precisely into the iag->inoext:

http://magnifier.sourceforge.net/tmp/jfs_inode_alloc_map_inoext.png

The inoext has [0], [1] and [2] filled but [8] is filled with zeroes
.. any ideas?

thanks,
