Help understanding doveadm-sync stateful
by Bruno MATEU 01 Feb '25

01 Feb '25

Hello, With the removal of the replication plugin in next releases, i'm trying to setup automatic synchronization using doveadm sync between my master and my replica. I managed to make the full sync work from my replica using the following comamnd `sync -A -N -R -f tcp:master-fqdn:12345` However i'd like to do stateful synchronization to avoid doing the full replication each time, and i haven't managed to do that. I tried the following: `doveadm sync -A -N -R -s "$(</var/lib/dovecot/… [View More]

Different Replicator Crash??
by Kent Borg 31 Jan '25

31 Jan '25

I added the suggested "count--" and recompiled, and it now appears to work, the replication goes both ways, eyeballing the e-mail on the two servers they look the same. Good. But part of the time I am still getting what looks very much like the same crash, is there another "count--" I need to add to that file? > Jan 28 10:53:08 la dovecot[96175]: replicator: Panic: data stack: Out > of memory when allocating 268435496 bytes > Jan 28 10:53:08 la dovecot[96175]: replicator: Error: … [View More]

Replication Question: Who Initiates?
by Kent Borg 31 Jan '25

31 Jan '25

As I understand it, if I am doing replication between a pair of servers, I run the replicator on just one and it makes all the two way changes necessary to make the two machines match. But this only happens when some change happens on that machine that runs the replicator. First, is this correct? If so, is there a way to have that other machine give the first machine poke, to get it to run a replication? Thanks, -kb

My new custom-built .deb packages seem to work, or at least work better! When new e-mails come in, it quickly attempts a sync, but says it fails: > Jan 29 10:31:49 la dovecot[1199]: doveadm: Error: > doveadm(kentborg)<2465><gL2eARV0mmehCQAAA3PmQQ>: Warning: Failed to do > incremental sync for mai\ > lbox INBOX, retry with a full sync (Modseq 34839 no longer in > transaction log (highest=37557, last_common_uid=12476, nextuid=12614)) Is this a leftover problem … [View More]
