we're currently experimenting with the Cyrus Murder to build a IMAP server cluster infrastructure. I had setup a master mupdate server, a backend and frontend server. The server configuration looks like below:
Server A = master mupdate server | Server B = backend server with mupdate slave daemon | Server C = frontend server with all proxies enabled
All works fine, the backend synchronizes with the master correctly and the frontend servers works as expected. However, if i shutdown and restart the Cyrus IMAP server on the backend, _all_ mailboxes located on this backend becames unaccessable (when connecting through both, the backend and frontend servers). The following can be found in the logs:
Aug 26 15:07:28 fritz imap[9894]: login: td9091af2.pool.terralink.de [217.9.26.242] test CRAM-MD5 User logged in
Aug 26 15:07:28 fritz imap[9894]: IOERROR: opening fritz!fritz!fritz!default/cyrus.header: No such file or directory
Notice the weird mailbox location path.
Issueing the ctl_mboxlist -d command on the backend shows this:
fritz:~# su cyrus -c "/usr/sbin/ctl_mboxlist -d" user.test fritz!fritz!fritz!default test lrswipcda user.test.test2 fritz!fritz!fritz!default test lrswipcda
The mupdate master server shows the same. Synchronization after restarting the backend shows no errors.
Cyrus Version is Cyrus IMAP4 v2.2.8-Debian-2.2.8-1
TIA
