Hi, I have the following problem, I have a distributed replicated cluster set up with samba and CTDB, over fuse mount points<br>
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<br>
<br>
#### faulty mount point####<br>

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

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. <br>
<br>
I have an older cluster with similar issues, different gluster version, but a very similar topology (4 bricks, initially two bricks then expanded)<br>
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.<br>
<br>
I'm trying to reproduce it over a small virtualized cluster, so far no results.<br>
<br>
Here are the cluster details<br>
four nodes, replica 2, plus one arbiter hosting 2 bricks<br>
