sudo -u cyrus /usr/cyrus/bin/ctl_mboxlist -d > filename
and then after you have moved the old one out of the way (import over the old doesn't/didn't work well) then just do:
sudo -u cyrus /usr/cyrus/bin/ctl_mboxlist -u < filename
Before you start, let me clarify:
remove the files in /var/spool/imapdb/db -- and always do an rsync of /var/spool/imapdb to somewhere before starting in case things go horribly wrong.

Wow, that really stinks. At this point I dont really have a choice though. Can you give me specifics on how you made a flat text file backup and how you reconstructed things using that?

Subject: Re: Reconstructing Mailboxes - HELP!

Last time we had this problem we had to move mailboxes.db out of the way, remove everything in /var/spool/imapdb/ and then recreate our mailboxes.db file from a flat text backup and then run reconstruct, which takes awhile depending on you number of users.
Hopes this helps,

Cyrus: 2.1.9
We suffered some data corruption on our cyrus box and the mailboxes.db and the db/ folder were lost. When we start cyrus, ctl_cyrusdb just hangs with the following strace:
open("/export/cyrus/imap/mailboxes.db", O_RDWR|O_LARGEFILE) = 6
fcntl64(6, F_SETFD, FD_CLOEXEC) = 0
fstat64(6, {st_mode=S_IFREG|0600, st_size=294912, ...}) = 0
select(0, NULL, NULL, NULL, {0, 1000}) = 0 (Timeout)
select(0, NULL, NULL, NULL, {0, 2000}) = 0 (Timeout)
select(0, NULL, NULL, NULL, {0, 4000}) = 0 (Timeout)
select(0, NULL, NULL, NULL, {0, 8000}) = 0 (Timeout)
select(0, NULL, NULL, NULL, {0, 16000}) = 0 (Timeout)
select(0, NULL, NULL, NULL, {0, 32000}) = 0 (Timeout)
select(0, NULL, NULL, NULL, {0, 64000}) = 0 (Timeout)
select(0, NULL, NULL, NULL, {0, 128000}) = 0 (Timeout)
select(0, NULL, NULL, NULL, {0, 256000}) = 0 (Timeout)
select(0, NULL, NULL, NULL, {0, 512000}) = 0 (Timeout)
select(0, NULL, NULL, NULL, {1, 0}) = 0 (Timeout)
select(0, NULL, NULL, NULL, {1, 0}) = 0 (Timeout)
select(0, NULL, NULL, NULL, {1, 0}) = 0 (Timeout)
The last line continues forever.
Given the above, I assume the problem is a corrupted mailboxes.db file. Im trying to run reconstruct -rf on each of the mailboxes (since reconstruct -m is disabled), but doing so with the the old mailboxes.db/db folder does not fix the hanging ctlcyrus_db problem. If I delete everying in the db folder and i delete the mailboxes.db file, reconstruct complains that it cant open the mailboxes.db file. I tried using a fresh cyrus install's db/mailboxes and reconstruct again runs for 1 second then ends doing nothing. Strace just shows it opening the files.
Any help would be much appreciated.
Thanks,
Lee
