Simple multi-server setup

[barryk]

Hi,
I'm currently evaluating the network edition of zimbra. It is for a small office and will have about 15 mailboxes with moderate volume. I do not feel comfortable running on only one server, I would like some redundancy. All the multiple server documentation and forum posts that deal with this topic are too complex for my needs. Ideally I would like to run a main server and a second server to be the backup ldap, mx and have the ability to take over the mail store from a backup of the main system.

I set up the main system with no difficulties. When I go to add the second I have problems. Openldap does not start on a reboot on the second system, I have to remove the alock file. I also loose the statistics in the admin gui. Are there any pointers to this type of set up? Is it a worth while configuration?

Thanks!
Barry

I have had that happen as well, where ldap wont stay running unless I remove alock first.

For 15 users you may want to look at 2 different ways of doing it:

1. Look at an hosting partner (can provide much better infrastructure for a few dollars a month per mailbox
2. Run you server in a RAID 1, so you have mirrored discs.

If you want true redundancy you will want a cluster (not multi-server). Look at the RHCS option.

I am running raid1. I have two servers to use for mail. I don't really need a full cluster and want to provide a little redundancy. The second machine will simply be a backup MX server and have the ability to take the backups from the first machine and "take over" if the first one dies. The "take over" can be manual to meet my needs.
