[Gluster-users] Duplicate files after 8.2 -> 8.3 upgrade

[Eli V]

Googling around I see this has been happening for years, with
apparently no one ever understanding why. The files are now on 2
bricks of each of the 3 replica nodes in my cluster, and the gfids all
appear identical, per below. I guess I'll plan on deleting a copy
directly under one of the bricks after the heal finishes. I'll be
happy to provide more info or logs if someone is interested in looking
further.

pdsh -w glust0[5-7] getfattr -m . -d -e hex /bricks/b*/br/<filepath> |
