Hi Gordan,
About the costs, I am talking about Brazil, a ready made SAN, redundant,
with all we need, will be around 100K GBP.
That's fairly ridiculous. You should be able to build your own for a tiny
fraction of that. To give you an idea, here in UK I've put one together
recently for 14x less than that (24TB of storage). So let's call it 7x
less for 2x 24TB in RAID 61 arrangement. 15K UKP for the lot. Obviously,
there is parts only, but it doesn't take long to get it all up and
running.
I need replication because the same user can one time be redirected to one
server and the other time, he/she can be redirected to the second server.
So, the servers have to be syncronized.
About the solution using DRBD, does it work with a partition or have to be
a whole disk?
I think it doesn't even have to be a partition. It can be a file. You can
always use loopback to mount an image as a drive.
Do you know about any example/case of someone who used DRBD/GFS for a setup
like our one, with loadbalancing and courier serving multiple users/domains?
Look at Linux clustering. That's where you'll find info on DRDB/GFS type
things. I have a SAN/GFS based system doing this sort of thing with
Postfix/Dovecot, but there is no reason it would work just the same with
Courier, and there's also no reason why DRDB wouldn't work as well as any
SAN.
