Actually the filesystem is also shared via FUSE mounts on Linux clients.

My understanding so far was that posix and strict locking set to yes 
would cause an unnecessary performance impact, whereas other options 
were tried in the context of this troubleshooting. Will revert them to 
their default.

And to close on this thread, I'd suggest to document the vfs objects 
parameter in the CTDB documentation, as it's a pretty unintuitive one to 
find out when configuring a samba cluster.

Thanks a lot,
Cheers,
