.glusterfs directory in the brick root contains metadata about the data
stored in bricks. While the directory was moved, could it be possible that
metadata in .glusterfs was not cleaned up?

output of `heal <volname> info`  is derived by looking up metadata in
.glusterfs and that metadata would need to be cleaned up, if stale, for the
heal commands to function properly. You could move/unlink contents that
correspond to stale data in .glusterfs/indices/xattrop directory under the
brick root to have a clean state.
