Couldn't create lock .dovecot-sync.lock

[listas at adminlinux.com.br]

Hi,

In a cluster with two servers and replication via dovecot-dsync, this 
error is logged:
server1 dovecot: dsync-server(<user>): Error: Couldn't create lock 
/var/lib/imap/user/6a/<user>/.dovecot-sync.lock: No such file or directory

This is because "/var/lib/imap/user/6a/<user>/" doesn't exist in 
server1. In another cluster node, the directory exists and everything 
seems to work fine.

In my view, this indicates that the first sync is failing. In the first 
user access Dovecot creates home_dir for him. But the sync is not 
happening at this time to create the home_dir on the other node.

My confs with doveconf -n:

Thanks in advance!
