Clustered Samba: Witness Protection Programming


This talk will cover two new clustering features under development for Samba: Persistent Handles and the Witness service. Alongside a scale-out filesystem such as CephFS, both features can be combined to provide transparent client failover and automatic load balancing.

The presentation will finish with a recap of ongoing and outstanding clustered Samba tasks, focusing in particular on CephFS integration.

This talk is intended for developers and users familiar with Samba.
