That didn't fix it unfortunately. In fact, I've done a full rebalance after initially discovering the problem and after updating Gluster, but nothing was changed..
I don't know too much about how Gluster works internally; is it possible to compute the hash for each duplicate filename - figure out on which brick it belong is and find where it actually resides, then recreate the link file or update the linkto attribute? Assuming broken link files are the problem..

I'm wondering if this is from a corrupted failed rebalance. In a directory that has duplicates, do "setfattr -n trusted.distribute.fix.layout -v 1 ."
If that fixes it, do a rebalance...fix-layout

Should be safe.
Here's what I've done in the past to clean up rogue dht link files (not that yours looked rogue though):
find $brick_root -type f -size 0 -perm 1000 -exec /bin/rm {} \;

Is rebalance running on this volume right now? If not, can you please
move out the file copy with "trusted.glusterfs.dht.linkto" attribute out
of the brick directory
(/data/glusterfs/safari/brick00/brick/complete/vancouver/refdem/tif2flt.pro)
to an alternate location & check the behavior?
Thanks,
Vijay
