Cluster/Clone spamassassin node
Good morning, I am preparing env with more then 10 node of spamassassin machine. I am wonder what kind of software do you use to clone OS and Spamassassin application to the other machine. I am gonne use Debian, I find FAI but it won't migrate SA database. So it isn't the best choise. What it your experience?

So it isn't the best choise. We use cfengine to install, configure software and also to check for compliance. As for databases I recommend using a SQL backend and have the SQL servers in some sort of HA master-slave setup. p...@rick -- state of mind Digitale Kommunikation http://www.state-of-mind.de Franziskanerstraße 15 Telefon +49 89 3090 4664 81669 München Telefax +49 89 3090 4666 Amtsgericht MünchenPartnerschaftsregister PR 563

But there's an enormous number of alternatives starting from rsync to cluster filesystem solutions as others already have pointed out. Another concept may be to have the clients load their config from a database. You can't load everything this way, but it may suffice. It depends on your setup. You may want to let us in on the details and we may be of better help. p...@rick -- state of mind Digitale Kommunikation http://www.state-of-mind.de Franziskanerstraße 15 Telefon +49 89 3090 4664 81669 München Telefax +49 89 3090 4666 Amtsgericht MünchenPartnerschaftsregister PR 563

> You may want to let us in on the details and we may be of better help. Okay, so: I'm preparing ~10 machine of Debian Lenny with spamassassin on the board. Configuration (hardware&software) of each of those nodes will be almost the same (excluding ip address, hostname etc.). What kind of software I should use to manage those nodes? I can always use rsync and write lots of excludes (/dev, proc etc.) to make copy of one OS with application to another (and some postcopy script to HUP the app). I have done some research and I find that systemimager should be the one. But nowadays it isn't supported by Debian and the last modification comes from 2007. It looks like someone abandoned the ship. So what now? Cfengine, puppet, fai do some other stuff. None of them isn't design to mirror not only conf files but also content of the whole operating system and application with its configs (!logs). Maybe I am wrong? Maybe cfengine/puppet can do the work?

It looks like someone abandoned the ship. ever thought about using virtual hosts? They could be cloned easily and using dhcp, the setup of each machine could be identical. For bayesDB see hint in previous mail about SQL-slaves. -- Regards Frank

I would say that the problems lies in those machines' performance, which can't be solved by virtual hosting - you would have the same problem with configuration of IP addresses etc. Or is there any way of making those easier with virtual hosting? -- Matus UHLAR - fantomas, uh...@fantomas.sk ; http://www.fantomas.sk/ Warning: I wish NOT to receive e-mail advertising to this address.

Re: Cluster/Clone spamassassin node
I use dd to duplicate hard drives when needed. dd if=/dev/sdb of=/dev/sdc bs=1M for example. It's probably in every distribution. I use rsync to sync up system wide files such as authentication, etc... and on a per user basis it copies users' .procmailrc and .spamassassin/* files from a central server. I use perdition to load balance the mail checking, and load balancing of SA/AMAVIS/CLAMAV and checking is managed by having certain letters of the alphabet (for first letter of username) going to certain mail servers. I've considered using mysql to make the SA settings available to each server, but I'd still need rsync to copy passwd/shadow files, .procmail files, and so on. Virtualization was presented, but I think for absolute speed, you'll want to run the OS natively. I use virtualization for lots of things, but really heavy duty email isn't one.

I've found that to quite manageable for a low number of nodes. /Per Jessen, Zürich
