[Gluster-users] Hundreds of duplicate files
No, the files can be read on a newly mounted client! I went ahead and deleted
all of the link files associated with these duplicates, and then remounted the
volume. The problem is fixed!
Thanks again for the help, Joe and Vijay.

Is this behavior seen with a freshly mounted client too?

Hi all,
I'm have this problem after upgrading from 3.5.3 to 3.6.2.
At the moment I am still waiting for a heal to finish (on a 31TB volume
with 42 bricks, replicated over three nodes).
Tom,
how did you remove the duplicates?
with 42 bricks I will not be able to do this manually..
Did a:
find $brick_root -type f -size 0 -perm 1000 -exec /bin/rm {} \;
work for you?
Should this type of thing ideally not be checked and mended by a heal?
Does anyone have an idea yet how this happens in the first place? Can it
be connected to upgrading?
Cheers,
Olav
