Hi, Cyrus has 2 problems with NFS. 1. Cyrus depends on filesystem locking. NFS-4 should have solved this problem but i have not tested it. 2. BerkleyDB uses shared Memory which does not work accros multiple servers.You can try to convert all your databases to skipplist and run with NFS-4 and proper filesystemlocking.
But as far as i know only skiplist and GFS is tested in a setup like yours. Have a look at the threads on Cyrus and Cluster Filesystem and Cyrus HA.Some time ago i wrote a summery of the infos in these threads, and wanted to add it to the Wiki, but had no sucsess so far.

I testing cyrus with a NFS storage by two *identical* cyrus + postfix servers Both /var/spool/imap and /var/imap are mounted by both servers ( the socket directory is moved out of the mount) Everything seems working fine but I find sometimes dupelim doesnt work. I tried to debug , I get errrors like these in my maillog DBERROR: skiplist recovery /var/imap/deliver.db: ADD at E2C8 exists What could be the reason ? I am using cyrus-imapd 2.3.7 on centos 4.4 on both servers , with a NetAPP box for storage Thanks Ram ---- Cyrus Home Page: http://cyrusimap.web.cmu.edu/ Cyrus Wiki/FAQ: http://cyrusimap.web.cmu.edu/twiki List Archives/Info: http://asg.web.cmu.edu/cyrus/mailing-list.html
