Urgent help needed - ctl_cyrusdb[3698]: DBERROR db3: /var/imap/mailboxes.db: unexpected file type or format

[Oliver Simon]

Hi all,

Thanks to Ken, who has given me the straight tip !
What helped was the following:

./db_recover -c -v -h /var/imap/db.backup2 -t 20031215

-c means catastrohpical recover
-v verbose (where verbose seems to be a very relative thing, for 1 1/2
hours I did not see what the machine is doing ...)
-h home of the location to recover
-t timestamp to go back to [CC]YYMMDD[hhmm]

This, I think, recovered the file to a format, that cyrus was happy
with, again.

Immediately after the successful recover, I installed an amanda and did
a big backup ;-) , now maybe I can sleep a little better ...

Thanks ! ...olli
