I suspect it has something to do with that warning on client log, which happens
once:

[2013-12-25 06:04:00.111064] W [client-rpc-fops.c:1744:client3_3_xattrop_cbk]
0-gfs351-client-0: remote operation failed: Undefined error: 0. Path:
/manu/usr/src/games/backgammon/common_source/obj/one.o
(cf1bdf4f-b71c-4fda-963d-b7e4547e1b7c)

Althought the index does not exist, the file does:
silo:/export/wd2a//manu/usr/src/games/backgammon/common_source/obj/one.o
hangar:/export/wd1a//manu/usr/src/games/backgammon/common_source/obj/one.o

Both have same extended attributes:

trusted.afr.gfs351-client-0     
   000   00 00 00 00 00 00 00 00 00 00 00 00                ............    
trusted.afr.gfs351-client-1   
   000   00 00 00 00 00 00 00 00 00 00 00 00                ............

For parent directory, trusted.gfid is the same on all bricks.
trusted.glusterfs.dht it:
silo:/export/wd2a//manu/usr/src/games/backgammon/common_source/obj   
   000   00 00 00 01 00 00 00 00 00 00 00 00 7f ff ff fe    ...............
