Hi,
I have a discrete cyrus setup with two frontends, several backends and a single
murder.
On the murder server I would like to dump out the mailboxes.db into a plain
file, for doing sed/grep modifications then push it back. I'm facing with an
inconsistence where the dump made on murder does not contains the backend's
hostname.
on murder :
ctl_mboxlist -d |grep 'my own mailbox'
illusion.hu!user.imre 1 common i...@illusion.hu lrswipkxtecda
It tells me that is a remote (1) mailbox on partition common. But on which
backend host?
on backend:
ctl_mboxlist -d
illusion.hu!user.imre 0 common i...@illusion.hu lrswipkxtecda
looks good, it's a local mailbox on common partition
on frontend:
ctl_mboxlist -d
illusion.hu!user.imre 1 cyrus-common!common i...@illusion.hu lrswipkxtecda
looks good, it's remote (1) on host 'cyrus-common' on partition 'common'
On murder the mailboxes.db does contain the missing information. I converted to
db file to flat, got this:
illusion.hu!user.imre 1 cyrus-common!common
i...@illusion.hu<FF><89>lrswipkxtecda<FF><89>
On murder I'm using 2.5.10-3ubuntu1.1 version (ubuntu Bionic build)
I digged into the code, imap/ctl_mboxlist.c +183:
case DUMP:
if (!d->partition || !strcmpsafe(d->partition, mbentry->partition)) {
printf("%s\t%d ", mbentry->name, mbentry->mbtype);
if (mbentry->server) printf("%s!", mbentry->server);
printf("%s %s\n", mbentry->partition, mbentry->acl);
if (d->purge) {
mboxlist_delete(mbentry->name);
}
}
how can the mbentry->server be empty in my case?
The site is operational, it works fine in live, but after a dump/undump in
murder all my clients started to complain about dissappeared mailboxes. That
made evidence that the frontend configurated properly, using the murder's
database as a master.
This problem is serious for us:
- one of our backend has destroyed, we need to purge the unused mailboxes from
database
- we want to change the hostname of a backend and want to avoid mailbox
deletion after 'mupdate -m'
- our mailboxes.db backup on murder is useless.
Please give me advices how to handle this case. If any detailed information is
needed I'm happy to send.
