Hi
I'm trying to build a cluster of two servers with dsync replication
(based on http://wiki2.dovecot.org/Replication). My test setup works
fine for very simple tests, I can log in to both servers, copy a
message to one of the servers and it successfully apperars in the other
account. But, if I try to copy a large amount of messages at once to
one of the accounts, my maillogs get flodded with errors(see below) and
the mailboxes seem to get out of sync and messages are duplicated over
and over again (I originally copied 100 messages and ended up with
thousands in both mailboxes until I killed dovecot)
I'd appreciate if someone could have a look at my config and tell me
what I did wrong.
dovecot.conf of both servers, they are identical except for the target
ip in mail_replica:
dovecot -n
# 2.2.beta1 (070ca24e5846+): /etc/dovecot/dovecot.conf
# OS: Linux 2.6.32-279.19.1.el6.x86_64 x86_64 CentOS release 6.3
(Final) disable_plaintext_auth = no
mail_plugins = " notify replication"
namespace {
inbox = yes
location =
prefix =
separator = /
type = private
}
passdb {
args = /etc/dovecot/dovecot-sql.conf
driver = sql
}
plugin {
mail_replica = remote:vmail at 192.168.23.62
}
protocols = pop3 imap
service aggregator {
fifo_listener replication-notify-fifo {
user = vmail
}
unix_listener replication-notify {
user = vmail
}
}
service auth {
unix_listener auth-master {
group = vmail
mode = 0660
user = vmail
}
user = root
}
service replicator {
process_min_avail = 1
}
ssl = no
userdb {
args = /etc/dovecot/dovecot-sql.conf
driver = sql
}
Log on server1 after I copied 100 messages to an account on that server:
