[Gluster-users] missing files on FUSE mount

Hi, I have the following problem, I have a distributed replicated cluster
set up with samba and CTDB, over fuse mount points
I am having inconsistencies across the FUSE mounts, users report that files
are disappearing after being copied/moved. I take a look at the mount
points on each node, and they don't display the same data
#### faulty mount point####

- So far the only way to solve this is to create a directory in the
healthy mount point, on the same path:
[root at gluster7 ARRIBA GENTE martes 20 de octubre]# mkdir hola
- When you refresh the other mountpoint, and the issue is resolved:
[root at gluster6 ARRIBA GENTE martes 20 de octubre]# ll

Interestingly, the error occurs on the mount point where the files were
copied. They don't show up as pending heal entries. I have around 15 people
using them over samba, I think I'm having this issue reported every two
days.
I have an older cluster with similar issues, different gluster version, but
a very similar topology (4 bricks, initially two bricks then expanded)
Please note , the bricks aren't the same size (but their replicas are), so
my other suspicion is that rebalancing has something to do with it.
I'm trying to reproduce it over a small virtualized cluster, so far no
results.
Here are the cluster details
four nodes, replica 2, plus one arbiter hosting 2 bricks
I have 2 bricks with ~20 TB capacity and the other pair is ~48TB
