[Gluster-users] Hundreds of duplicate files

[tbenzvi at 3vgeomatics.com]

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..
 
Tom

 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
