I know one older "smaller" cyrus setup with i.e. 100 IMAP/POP-Users which has
it's complete spool and db (!) on NFSv3 over a Fast Ethernet Switch what works
quite OK (as long as we do not want to place a backup restore of the whole
spool over that NFS which is slow).
The mount is just default but relatime and local_lock=none which may be
suboptimal by performance - it could make sense to held locking local only or
to disable it completely if you just have one NFS Client with a "single"
CYRUS. It may make sense to disable locking (at least remote locks) as it may
not be required in that scenario.
Holding the db locally could improve performance, but it seems that the OS
caching / buffering mechanisms are "enough" there in that old setup.
Any further hints / experiences here for different NFS mount options / locking
options are welcome - until today we do not run any further cyrus on NFS.
It makes sense to monitor the cyrus services (service based) and the NFS mount
and if it fail's, you should take care to repair the NFS mount and restart
cyrus. Your cyrus conf should have a recover line within start and after such
a "crash" a cyrus "reconstruct" run could make sense too.
The spooler before LMTP held all messages qeued if the LMTP is not working
properly.
many thanks and best regards,
Niels.
