[Gluster-users] Hundreds of duplicate files

[tbenzvi at 3vgeomatics.com]

Ok, I am really tearing my hair out here. I tried doing this manually for several other files just to be sure. And in these cases it removed the duplicate file from the directory listing, but the file can still not be read.. Reading directly from the brick works fine.

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 {} \;

 Moving the file with linkto attribute worked! Just one copy of the file is retained in the listing and can be read without problems.
I will write a script to remove these rogue link files from the bricks - any risks associated with this?
 
Thanks everyone for your help, of course if anyone could explain how this happened I would love to hear it..

 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
