Hello, from your message it is unclear whether you are doing inplace upgrade, or upgrade over replication. It is unclear also from which version you are upgrading.
I cannot help you why this happens, but providing the form of upgrade might give hints others to assist you. Greetings Dilyan -----Original Message----- From: lode.mert...@axsguard.com Reply-To: Devel <devel@cyrus.topicbox.com> To: Devel <devel@cyrus.topicbox.com> Subject: reconstruct uniqueid clash Date: 05/30/2024 02:49:20 PM I asked the same question on the info list, but nobody seems to know the answer. So hopefully a developer can give me some insights. When upgrading to version 3.8.1 we ran a reconstruct on all our mailboxes. This resulted in a few mailboxes with errors on standard out: Wrong uniqueid! user.xxxx.yyyy (should be user.xxxx.yyyy.zzzz) And in syslog: SYSLOG err reconstruct[24248] uniqueid clash with user.xxxx.yyyy - changed user.xxxx.yyyy.zzzz (1a0fb7b061375d7a => 1a0fb7b061375d7a) We tried reconstruct with multiple flags: reconstruct -I -x -M -u xxxx reconstruct -G -I -rf -u xxxx But reconstruct doesn't seem able to fix the issue. Is there a way to fix this issue? Because this stops us from running "relocate_by_id" Creating a new mailbox and then copying over all mails and running reconstruct seems to resolve the issue, but doing this on terabytes of data will likely result in multiple days of downtime. ------------------------------------------ Cyrus: Devel Permalink: https://cyrus.topicbox.com/groups/devel/Tc0ed6ec2ac8bfb94-M284095864e8eb3e353942884 Delivery options: https://cyrus.topicbox.com/groups/devel/subscription
