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 ? # duptype id depth size device inode priority name DUPTYPE_FIRST_OCCURRENCE 1030757 3 842 2065 330967752 3 /var/spool/cyrus/mail/c/user/user1/15384.
