Cyrus replication
saved my ass the other day when my 'master' replica server failed. Now the
'replica' server has become the new master, and I've set up a new replica. I've
pretty much copied the master configuration on the ex-replica and all wen well
with this hitch.
The old master used
UUIDs ( sync_machineid:1) but using the same configuration on the ex-replica
gave this in syslog:
Jul 27
00:00:00 exreplica master[23136]: Machine mismatch: 1 !=
2
Jul 27
00:00:00 exreplica master[23136]: Couldn't initialise UUID
subsystem
cyrus virtually hung
up, to make it restart I had to disable UUIDs and delete deliver.db, which was
corrupted. Then I tried using a sync_machineid:2 in imapd.conf with the
corresponding provide_uuid in cyrus conf, and everything went
ok.
But I've never set a
"2" machineid on the replica-now-working-as-master, such a setup is not
mentioned in the documentation I've read. So it probably has to be had set
automatically, but... where ??
