Hi,
I have a failover cluster for mail server with: Ubuntu12.04 + DRBD (for block replication) + Ext4 filesystem
- Dovecot-2.0.19-2 with Mdbox
It works fine with ~50k accounts. My cluster design: http://adminlinux.com.br/cluster_design.txt
I plan to test Dovecot Replication with dsync to build an active/active cluster with load balancing. Can anyone direct me to some literature? A tutorial for example.
I'm installing a cluster (for tests) with Ubuntu 14.04 + Ext4 filesystem (without Drbd) + Dovecot-2.2.9-1ubuntu2.1. My conf is in: http://adminlinux.com.br/replication-doveconf.txt
I'm following this doc http://wiki2.dovecot.org/Replication but I'm getting some errors:
- Aug 14 15:39:34 ceph1 dovecot: imap(account=domaintest.com): Error: open(/var/run/dovecot/replication-notify-fifo) failed: Permission denied
What is the correct perms for /var/run/dovecot/replication-notify-fifo ? Currently: # ll /var/run/dovecot/replication-notify-fifo prw------- 1 root root 0 Aug 14 15:57 /var/run/dovecot/replication-notify-fifo|
- Aug 14 16:02:34 ceph1 dovecot: dsync-server(account=domaintest.com): Error: Couldn't create lock */var/lib/imap/account=domaintest.com http://domaintest.com/*.dovecot-sync.lock: No such file or directory Aug 14 16:02:34 ceph1 dovecot: dsync-local(account=domaintest.com): Error: Couldn't create lock */var/lib/imap/account=domaintest.com http://domaintest.com/*.dovecot-sync.lock: No such file or directory
In my production cluster, it is automatically created by dovecot when the user performs the first login: */var/lib/imap/*<account> for INDEX */var/spool/imap/*<account> for Mdbox
Thanks!
