Are you considering using coda between fileserver and front end mail servers? I'd be quite scared of doing that, because: │ disk. Coda has several advantages over NFS: support for │ disconnected operation (e.g. for laptops), read/write server │ replication, security model for authentication and encryption, │ persistent client caches and write back caching. OK, so disconnected operation is great for a laptop, but bad bad news for a farm of mail servers, with any mailbox format, especially maildir, as they'd very quickly get into a inconsistant state. In theory, if you hard mount an NFS share and the server goes away the client will just hang, until the server reappears. Doubly in theory if a secondary server (the previously mentioned DRBD mirror of it) does some arp magic and steals the primaries IP NFS will reconnect fail the transfer try again, or bounce the message with a temporary problem. - -- Mike Williams -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.3 (GNU/Linux) iD8DBQE/j/7QInuLMrk7bIwRAo+1AJ47OiOuFfx/S3cRQLUv42nsl+eB7wCfaUkB W1sqdGF/P07SLkVLr2fe5H4= =MDCw -----END PGP SIGNATURE-----
