Hi Michael, years ago I had a similar problem :(.
You can use reconstruct to recreate the mailboxes.db file. However in
case of many TB of data this can take too long. But note the
following options to reconstruct
-f Examine the filesystem underneath mailbox, adding all directo-
ries with a cyrus.header found there as new mailboxes. Useful
for restoring mailboxes from backups.
-s Don't stat underlying files. This makes reconstruct run faster,
at the expense of not noticing some issues (like zero byte files
or size mistmatches). "reconstruct -s" should be quite fast.
In my case, I don't think -s existed then, I used 'find' to get a list
all the mailboxes and used a script to create the mailboxes.db
contents as a text file. I then converted that txt file to the db
file with one of the tools that comes with cyrus. (ctl_dbtool). The
only catch is that the txt file needs to have a tab at the end of the
line (or something like that.)
Good luck!
Rudy
