dsync: assert panic on mbox // no INBOX sync on hybrid mbox/maildir
Hi,
This (hopefully!) might be a case of user error, as I'm new to
dovecot... Alternatively it might be some confusion in an index, since
I've been mucking about trying different things in my configuration
files and had frequent crashes.
I'm trying to sync 2 (LAN) hosts, ideally to have full automatic
replication happening.
They both have hybrid mbox INBOX and maildir++ folders, using
namespaces, as suggested in the wiki. I might have deviated the config
from the wiki version, in trying to get things working.
Both hosts communicate perfectly with an external IMAP client (thunderbird).
Replication is working, but only partially - it is syncing the folders
but not INBOX. I've thus been trying various things to try to get the
INBOX to sync.
The crash is only happening one of the 2 hosts which I've named
crashhost for this report. The process crashes no matter which host
starts the sync.
With a second user, the crash happens on the other host
crashhost: Ubuntu 16.04, x86_64, laptop, Dovecot 2.2.22, and Dovecot
2.2.32 (from debian sid package, locally compiled)
otherhost: Ubuntu 16.04, x86_64, desktop, Dovecot 2.2.22, and Dovecot
2.2.32 (from debian sid package, locally compiled)
RESULTS:
1) doveadm sync -f -u david tcp:otherhost
synchronises the folders, but does not touch INBOXes.
2) doveadm sync -f -m INBOX -u david tcp:otherhost
Does not touch INBOXes
3) doveadm sync -n '#mbox/' -f -u david tcp:otherhost
dsync-local(david): Panic: file mbox-lock.c: line 800 (mbox_lock):
assertion failed: (lock_type == F_RDLCK || mbox->mbox_lock_type !F_RDLCK)
I added some debug code, the assertion failure is being triggered by a
call to mbox-lock() with:
locktype=F_WRCLK mbox->mbox_lock_type=F_RDLCK,
mbox->external_transactions=1
The config files on the 2 hosts only differ by the hostnames they're
supposed to be syncing to.

dsync: assert panic on mbox // no INBOX sync on hybrid mbox/maildir
Why not do maildir format with the Inboxes as well? When every single email is its own file, it makes synchronization so much easier.? You could use rsync for one-way or unison for multi-master (two-way) Dave On 9/26/2017 3:39 PM, David Gardner wrote:> Hi, > This (hopefully!) might be a case of user error, as I'm new to > dovecot...

dsync: assert panic on mbox // no INBOX sync on hybrid mbox/maildir
Hi, replying to my own issue: The dsync crash seems to be triggered when there are emails to copy in both directions, and it's fairly clear from comments in the code that it should be releasing a read lock before trying to grab a write lock. A work-around for the crash was doing a one-way sync manually. This allowed the process to complete and my setup is now replicating properly. I guess as long as I don't trigger changes on both hosts David On 26 September 2017 at 22:39, David Gardner <somloieater at gmail.com> wrote:> Hi, > This (hopefully!) might be a case of user error, as I'm new to > dovecot...
