Hi Eli, remounting the volume fixes it. So, regarding cache invalidation, which volume options should I modify in order to minimize it? I cannot use gluster vfs on samba since it is broken on 4.10.5 https://lists.samba.org/archive/samba/2019-June/223683.html Also, is it correlated to system load?. I'm planning to upgrade CPU/RAM on a pair of nodes to see what happens...
