[Samba] gracefully killing samba sessions on ctdb node restart?

[Georg Muelleder]

Hi guys,

We are currently running a clustered samba setup with 3 nodes very 
successfully.

The only thing that bothers me is that whenever we change permissions on 
a shared directory, we have to restart ctdb on the nodes where affected 
users are still connected to push the changed permissions to the hosts 
by basically killing their connections and thus forcing them to reconnect.

However, this does not always work out as intended, because ctdb somehow 
does not kill its respective samba processes.

I think there is a feature in SMB2(.1? I'm not sure anymore) and up 
which does exactly what we try to accomplish in the fist place (push 
updated permissions to the clients), but for some reason i don't 
remember atm, we can't upgrade to SMB2.1 or higher.

Is there a best practice to handle such situations with "old" SMB?


regards,

Georg
