Weird, now I find them, while I could not inthe first place. Did I miss
them, or was it re-created afterward? (can it have the sam ehash?) Anyway:

Brick1 and brick 2 both have:
.glusterfs/50/24//5024cce3-a713-4bc4-acbc-129a4f2f0a66
Same trusted.gfid, 
brick1;trusted.afr.gfs351-client-0
   000   00 00 00 00 00 00 00 00 00 00 00 00                ............ 
brick1;trusted.afr.gfs351-client-1
   000   00 00 00 01 00 00 00 00 00 00 00 00                ............ 
brick2;trusted.afr.gfs351-client-0
   000   00 00 00 02 00 00 00 00 00 00 00 00   
brick2;trusted.afr.gfs351-client-1
   000   00 00 00 00 00 00 00 00 00 00 00 00                ............   

Brick 2 also have this, without any xattr and with size set to 0:
.glusterfs/indices/xattrop/5024cce3-a713-4bc4-acbc-129a4f2f0a66

Using inode number, I can find the culprit:
manu/usr/src/sys/arch/i386/compile/obj/GENERIC/midway.o

md5 show the file are the same, hence this is really a false positive.
