Hi Gregoire,


[..] with ~1 mailboxes located on a Lustre file system. So far so good.
This may be a bit off topic but... I thought that a lustre filesystem 
was not designed to store a lot of small files (e.g: due to MDS inodes)


Can you tell us more about your experience ?

Thomas

If there's just one Dovecot server accessing mails, there shouldn't be
any problems. If there are more, you should read
http://wiki2.dovecot.org/MailLocation/SharedDisk and stress test the
same mailbox at the same time from 2+ servers using
http://imapwiki.org/ImapTest

[Dovecot] Dovecot and Lustre FS

2011-09-13 Thread Christian Gregoire 
Hello,

Right now, I'm using Exim and a customized version of an old (10 years 
old) Atmail POP3 server written in Perl, with ~1 mailboxes located on 
a Lustre file system. So far so good.

Though, I plan to migrate from Atmail to Dovecot, to provide our customers with 
IMAP support. Has anyone any experience with Dovecot on Lustre FS ?

Thanks

Christian
