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/sync-state)" tcp:master-fqdn:12345 > /var/lib/dovecot/sync-state. However this output a doveadm(username): Error: Saved sync state is invalid, falling back to full sync: Invalid base64 data for every user.
After looking at the state in /var/lib/dovecot/sync-state, i noticed that there is one line for every user with an associated state, plus one line with only a state. For some reason, the state is the same for every user, except one where the state is much longer.
Do i need to run the command for each user, and give as an argument the corresponding state ? Is it enough to run the doveadm sync command with -A argument if i give the state in the last line outputted by doveadm sync ? Is this the right way to do it ?
Best regards,
