Hello,
So basically this sieve replication support is still in some broken
alfa stage and one should not build production system on top of it.
I have found this older thread:
http://www.dovecot.org/list/dovecot/2013-February/088640.html
We came up with a few options for syncing:
1) rsync/unison ~/sieve every x seconds
2) move sieve dirs to separatate partition and sync with
gluster or drbd
3) patch roundcube managesieve sieve plugin to upload to both
managesieve servers (only roundcube can access managesieve in our
setup)
4) store sieve scripts in mysql and patch roundcube managesieve plugin
to directly access the db instead of using managesieve (we tried this,
but apparently sieve scripts read from db via dovecot dict can't have
more than one line? show stopper due to roundcube sieve plugin
needing
comments to parse the scripts)
The database solution would be perfect since the nodes are using a db
master-master cluster but at the time of that post this was not working.
My original 2.2.10 dovecot is around that time so I would have to
upgrade for that again and at the end it would might not work because as
he said roundcube using multi-line sieve scripts.
The problem with rsync is that rsync from where? If I rsync from
machine A -> B and let's say the user already have sieves on both nodes
and changes his holiday sieve on node B then the file will be
overwritten. I will give unison a try otherwise I have to put the sieves
on a shared filesystem like OCFS2 which imo is not reliable for
production either. When nodes lose connectivity that can end in kernel
crash, autoreboot on 1 node or both.

I do have those files in those directories:

I do see traffic arriving at MW when listening on the defined port
for
synchronisation (tcpdump), but the new default file at KB doesn't
become
synchronized:
MW> la /var/mail/.homedirs/mike/.dovecot.sieve
/var/mail/.homedirs/mike/.sieves/default.sieve
lrwx------ 1 vmail dovecot uarch 21 Jul 21 19:38
/var/mail/.homedirs/mike/.dovecot.sieve -> .sieves/default.sieve
-rw------- 1 vmail dovecot uarch 5898 Jul 21 19:38
/var/mail/.homedirs/mike/.sieves/default.sieve
If I do remove that file at MW and repeat "doveadm sieve put" at KB,
I
do see synchronization succeed:
MW> rm /var/mail/.homedirs/mike/.sieves/default.sieve
MW> la /var/mail/.homedirs/mike/.dovecot.sieve
/var/mail/.homedirs/mike/.sieves/default.sieve
ls: /var/mail/.homedirs/mike/.sieves/default.sieve: No such file or
directory
lrwx------ 1 vmail dovecot uarch 21 Jul 21 19:38
/var/mail/.homedirs/mike/.dovecot.sieve -> .sieves/default.sieve
KB> doveadm sieve put -u mike -a default < default
KB> la /var/mail/.homedirs/mike/.dovecot.sieve
/var/mail/.homedirs/mike/.sieves/default.sieve
lrwx------ 1 vmail dovecot uarch 21 Jul 21 19:40
/var/mail/.homedirs/mike/.dovecot.sieve -> .sieves/default.sieve
-rw------- 1 vmail dovecot uarch 5909 Jul 21 19:40
/var/mail/.homedirs/mike/.sieves/default.sieve
MW> la /var/mail/.homedirs/mike/.dovecot.sieve

-rw------- 1 vmail dovecot uarch 5909 Jan 1 1970
/var/mail/.homedirs/mike/.sieves/default.sieve
The date of the file puzzles me, though.
JFTR: This is a recent FreeBSD and ZFS.
JFTR: The logfiles do show the very same messages as Claud has shown
in
his last mail.
