--- Comment #47 from Theodore Tso (tytso@....edu) ---
Bart, in #34, was the only thing which e2fsck reported this:

/dev/sda2: Inode 12190197 extent tree (at level 2) could be narrower.  IGNORED.

That's not a file system problem; it's a potential optimization which e2fsck
detected, which would eliminate a random 4k read when running random read
workload against that inode.  If you don't want to see this, you can use
e2fsck's  "-E fixes_only" option.
