    Default HA: merging two mailstores in one server on failure?

    Hi.

    I'm building a Zimbra multi-server installation with 2 stores (using a SAN), 2 ldaps, 2 mta and 2 proxies. Each store has its owns sets of accounts (namespace splitted between servers). The HA of ldap, mta and proxies is easy and it's solved but store HA is a little complex.

    Is there a way to merge all the accounts in one server on a node failure and restore them to the original place on failback? I know that I could have a third server as standby/backup of any mailstore but I don't want to have an idle server.

    My snap reaction is that you have to handle HA on a server by server basis, and yes, you'll need at least one idle spare server (assuming you're doing something like container based HA; if you're doing heartbeat failover, one spare per server).

    HA ain't cheap; that's one reason why "real" HA is so rare.

    Last time I looked into this, back in '92 with Motorola 88K based commercial HA servers, it was the difference between $6k and something like $44k.

    ok, but what about merging all accounts in one server. It's impossible? I need to modify all account objects if I want something like that?

    I'm sure you could merge all your accounts into one server... but not at failure time, I wouldn't think.
