Do you have the same ammount of clients connected to each brick ? I guess something like this can show it: gluster volume status VOL clients gluster volume status VOL client-list Best Regards, Strahil Nikolov В вторник, 20 октомври 2020 г., 15:41:45 Гринуич+3, Martín Lorenzo <mlorenzo@xxxxxxxxx> написа: 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.

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.
