Friends,I've got a Cyrus installation, at a client with roughly a dozen locations around the UA, which started life about 20 years ago and was split into a murder -- 2 frontends, 1 backend, 1 mupdate master -- several years back. At the time of the split, there were plans to geographically distribute portions of the mailstore, via the murder. However, before that project got very far, the client decided to make the leap to higher bandwidth Internet feeds, and then to an MPLS network, so the impetus for the murder has really gone away.
At this point, with an upgrade from 2.5.11 to 3.0.X imminent, it makes sense to un-murder (resurrect?) the systems. Is this possible? I'm assuming it would simply involve dumping the mailboxes.db, stripping out the murder-specific bits, and then reloading it. Is that correct? Or, given that there's only a single backend, is this even necessary; can I just use the mailboxes.db from the single backend?
Here's what a typical user's mailboxes.db entries look like on the murder's mupdate master:
user.onlight 1 mailbox.example.com!default onlight lrswipkxtecda cyradmin lrswipkxtecda cyradmin lrswipkxtecda user.onlight.Drafts 1 mailbox.example.com!default onlight lrswipkxtecda cyradmin lrswipkxtecda user.onlight.Junk 1 mailbox.example.com!default onlight lrswipkxtecda cyradmin lrswipkxtecda anyone p cyradmin lrswipkxtecda user.onlight.Sent 1 mailbox.example.com!default onlight lrswipkxtecda cyradmin lrswipkxtecda user.onlight.Trash 1 mailbox.example.com!default onlight lrswipkxtecda cyradmin lrswipkxtecda Here is the same excerpt from the backend's mailboxes.db: user.onlight 0 default onlight lrswipkxtecda cyradmin lrswipkxtecda cyradmin lrswipkxtecda user.onlight.Drafts 0 default onlight lrswipkxtecda cyradmin lrswipkxtecda user.onlight.Junk 0 default onlight lrswipkxtecda cyradmin lrswipkxtecda anyone p cyradmin lrswipkxtecda user.onlight.Sent 0 default onlight lrswipkxtecda cyradmin lrswipkxtecda user.onlight.Trash 0 default onlight lrswipkxtecda cyradmin lrswipkxtecdaAnd here's a similarly typical user's mailboxes.db entries from a non-murder setup of the same vintage:
user.onlight 0 default onlight lrswipcda cyradmin lrswipcda anyone p user.onlight.Drafts 0 default onlight lrswipcda cyradmin lrswipcda anyone p user.onlight.Sent 0 default onlight lrswipcda cyradmin lrswipcda anyone p user.onlight.Spam 0 default onlight lrswipcda cyradmin lrswipcda anyone p user.onlight.Trash 0 default onlight lrswipcda cyradmin lrswipcda anyone pSo, ignoring the obvious differences in some of the ACLs, it looks to me like the backend's mailboxes.db is just fine, and is all I would need. Is this correct?
In other words, all I really need to do is update the backend's cyrus.conf to reënable the various normal services, turn off the mupdatepush service, and Bob's your uncle, right?
