In general, using Cyrus over a distributed filesystem isn't going to result
in optimum performance. Cyrus makes use of mmap() heavily, and most
network filesystems don't implement mmap() efficiently. Further, file
system locking on many is either spotty or slow.

GFS turned commercial recently. There was a fork too, the GPL version
is at www.opengfs.org.

Excellent, but no news about co-existance with Cyrus Mail Spool

Veritas also has a Clustered Filesystem that will scale to eight nodes.

Probably nothing exists for solaris. Irix has cxfs (cluster-xfs) which

These appear to be LINUX products. Are they? Is anything available
for Solaris? Are these known to work with Cyrus?

Yeah, but you could do it the cheap way when applying SCSI with

Surprisingly, its not. Fibre HDDs are gotten a lot cheaper (same price as
SCSI), and fibre switches/h

Short answer: NFS and Cyrus don't mix.
Use GFS (www.globalfilesystem.org) or Intermezzo (www.inter-mezzo.org),
which provide local symantics over shared storage.

Hi All,
I need to setup a clustering IMAP mail server. So I'm planning to use a NAS
for storage) and couple of nodes with Linux OS. But when comes to File
System, I found that Cyrus IMAP server has problems with NFS file system.
Could you kindly update me with what other mechanism that I can use
