Wes,
thanks for the response. I still have the problem.

What error are you getting that indicates that mailboxes.db is
unreadable?
a bunch of places, but here's one:
sudo -u cyrus /usr/local/cyrus/bin/reconstruct -r -f user
fatal error: can't read mailboxes file
I suspect that the backups will also be unreadable, due
to the way they are made. If they *are* readable, as the cyrus user:
ctl_mboxlist -d -f db.backup1/mailboxes.db > somefile.txt
%ctl_mboxlist -d -f db.backup1/mailboxes.db > somefile.txt
fatal error: can't read mailboxes file
%ctl_mboxlist -d -f db.backup2/mailboxes.db > somefile.txt
fatal error: can't read mailboxes file
You'll want to examine "somefile.txt" to decide if it's more or less
reasonable. Then move mailboxes.db and the contents of db directory
out of the way. Run:
ctl_mboxlist -u < somefile.txt
You'll probably want to run:
ctl_mboxlist -d
again to see whether it worked.
OK, so that doesn't work. Now what can I do?
Also, the reconstruct -m thing is kind of misleading. reconstruct is
still available, and can be used to regenerate mailboxes.db from the
contents of the cyrus spool area. More or less :)
how do I use reconstruct to regenerate mailboxes.db from the contents of
the cyrus spool area?

I have a cyrus system with only about 20 users on it. They have
about 3 gigs of mail.
The mailboxes.db file is unreadable. of course, reconstruct -m is
unavailable, in typical dougadamsian fashion.
I have seen recommendations to try to 'rebuild the db' using the
'db.backup1' or 'db.backup2' directories. I have the dirs. What
specific command (including flags) do I use to attempt that?
i have seen use 'ctl_cyrusdb -r' but I keep getting segmentation
fault and core dump. I have tried that with and without my
corrupted mailboxes.db file in place. what does that tell us?
Since it's such a small system, a backup the mail spool, reinstall,
recreate user accounts type of approach would work for me if that's
the simplest thing to do... or just a 'run this command to get a
fresh mailboxes file'... but I don't know how.
Can somebody please give me a step by step here?
