I'm running Cyrus IMAP 2.3.7 in a CentOS 5.3 box. We have about 400 users, most of them POP3 users but some are IMAP users with their mail stored at the mailserver.
I recently had a out of space problem, so I removed so many unnecesary files (logs, backups, among others) and then restarted mail services (MailScanner, MySQL, ClamAV, Cyrus IMAP, etc)... but I had this problem with Cyrus IMAP:
# /etc/init.d/cyrus restart
Apagando cyrus-imapd: [ OK ]
Exportando la base de datos cyrus-imapd : [ OK ]
... ...
... ...
this takes so long that I decided to investigate what was the problem and I found that /var/lib/imap/db uses 21 GB. Is is normal that uses so many space? I found around 1700 files named log.000* and I just decided to not use them:
# cd /var/lib/imap
# mv db db2
# cp -a db.backup db
# /etc/init.d/cyrus-imapd start
And then Cyrus IMAP started correctly (because /var/lib/imap/db.backup ocuped just a few KB) but now IMAP users are telling me that their e-mails are gone! However I can see that all their mails are under /var/spool/imap/domain/X/XDOMAIN/u/user using a few hundreds of MB so I can believe that their emails aren't gone.
What happened to users emails? How can I recover them?
I would appreciate some help, thanks
