[Mailman-Developers] Mailman on a cluster

[Ian Eiloart]

Hi,

I'm looking at running Mailman on a cluster of servers, sharing a single 
disk with Apple XSan.

I presume that everything done through the web interface must be resilient 
to multiple simultaneous attempts to modify - say - a list membership. So, 
I expect that I can put the list databases on a shared file system.

But, what about the queue runners. Is it safe to share the queues between 
servers? If its safe to run multiple queue runners on one queue on one 
machine, then I should be OK - but I'm not sure that Mailman does that. If 
not, then I'm probably safer leaving the queues on unshared file systems, 
and accepting that a some queued items won't get processed while a cluster 
member is unavailable.
