Below is the backtrace that gives me EINVAL. Here is the relevant log
part:

[2012-08-18 11:07:10.731719] I [dht-layout.c:593:dht_layout_normalize] 
  1-vndfs-dht: found anomalies in /. holes=1 overlaps=0
[2012-08-18 11:07:10.738617] W [fuse-bridge.c:3597:fuse_migrate_fd] 
  0-glusterfs-fuse: name-less lookup of gfid   
  (b455c82f-1d34-4d48-a540-2c9ec9d51596) failed (Invalid argument)

The mess originates from dht_layout_normalize()/dht_layout_anomalies()
Is there some documentation explaining what it does, so that I can
figure how it goes wrong?
