Sorry for the multiples emails...
The option "provide_uuid=1" I found in my last message seems to be unrecognized by cyrus now (It's probably on by default). It's probably only useful for new messages anyway.
So I'm back to square one and my google-fu failed me. If someone know how to solve that problem any help would be greatly appreciated.
Cheers,
Adrien

Hello,
I set up replication between two cyrus servers (master runs 2.5.10 and
slave 3.0.8) with plans to decommission the old server once everything is
working. I noticed that the mail spool takes 950GB instead of ~300GB on the
old server. I suspected the hardlinks for message deduplication weren't
recreated so I ran rdfind on the mail spool and the tool found many
identical files. Is there a cyrus tool to recreate the hardlinks ? I looked
at the admin tools but I didn't find anything. Rdfind should work but it
also matched metadata such as cyrus.annotations for example. So I need to
go through the 600 mB dry-run log file to exclude unwanted files.
99% of the log file look like that : Are those safe to hardlink ?
