Hi -
I'm assembling some system documentation for a client and have been
pouring over my cyrus notes and looking at the man pages. A couple of
questions, starting with the simple one.
annotations.db: "This database contains mailbox and server annotations."
I still have no idea what this is used for. Can someone give me an
example of a mailbox or server annotation.
Next: Suppose I've completely lost /var/imap/mailboxes.db as well as
/var/imap/db.backup1 and /var/imap/db.backup2. Is there any way to
recover from this? Given that
/usr/lib/cyrus/bin/reconstruct -r -f user/userN
will add missing mailfolders to mailboxes.db, can I reconstruct
mailboxes.db by simply iterating over all mailbox directories?
# cd /srv/imap/user
# for i in $(ls)
# /usr/lib/cyrus/bin/reconstruct -r -f user/$i
# done
?
Finally a note on the documentation:
On this page:
https://cyrusimap.org/imap/reference/faqs/o-reconstruct.html
one finds the following comment: "If you do find yourself with a
corrupted mailboxes.db, there are a few things you can try. The first is
to see if db_recover can recover your database."
However, there is no db_recover listed under Tools & Utilities here:
https://cyrusimap.org/
/usr/bin/db_recover is installed on my system, so it exists, but there
isn't a man page for it, either, leading to wonder how one is supposed
to know what the syntax is for this command.
I guess that wasn't actually the final question. I'm currently running
version 2.5.10 and am thinking about upgrading to 3.0.1. The default db
format appears to be Twoskip, and I'm pretty sure that all my db files
are Skiplists. Is this going to be like the Berkeley DB to Skiplist
thing when upgrading from 2.2 to 2.4, where all the Berkeley DB
databases were automatically converted to Skiplists, or does a
conversion to Twoskip require some manual intervention?
Thanks in advance.
