Q3. Which of the filestores should I mount with the "noatime"
option? A3. Safe to use "noatime" for all three filestores. (I understand Dovecot will use utime() when needed on such filestores, but am not sure if it will work on the NFS-mounted filestores from the filer if access times are turned off at the filer end.)If your kernel caches atime updates locally, then maybe you shouldn't use noatime for message store until v1.1. It doesn't cause real problems, but Dovecot wastes time looking for old files in tmp/ directories all the time.
Many thanks! I think I'm nearly there now: could you just clarify on
the items flagged with (??) below?
In case it makes a difference, messages will generally be delivered
by a user's preferred IMAP server, but by Exim rather than Dovecot's
"deliver".
"actimeo=0" option
NFS-mounted Message Store: NOT needed, but if used can help spot
new messages
more quickly
NFS-mounted Control Files: REQUIRED for now
Local Index Files: Not applicable
"noatime" option
NFS-mounted Message Store: Probably OK to use, but safer not to
until v1.1
NFS-mounted Control Files: Can be used safely(??) (Or as above??)
Local Index Files: Can be used safely(??)
With many thanks, Mike B-)
