Hi all,
I've a little pb with 1.0-stable on nfs share without lockd :
with :
- lock_method = dotlock
- mmap_disable = yes I've :
- dovecot: Jul 22 11:58:33 Error: IMAP(xxxxxxxx): open() failed with
index file (null): Bad address
with :
- lock_method = dotlock
- mmap_disable = no I've :
- dovecot: Jul 22 11:59:47 Error: IMAP(xxxxxxxx): lock_method=dotlock
and mmap_disable=no combination isn't supported. You don't _really_
want it anyway.
Someone have an idea ?
Thanks,
Cyril Feraudet

You probably tried to set INDEX=MEMORY? That's not working with 1.0-stable. Would work with 1.0-tests.
With 1.0-stable + NFS maybe the best idea would be to store indexes somewhere in local disk, eg. /tmp. 1.0-tests support indexes in NFS somewhat better than 1.0-stable but it's still not perfect either.

Finally I have do that (store indexes in local).
At this time, I've 4 servers with Dovecot (ldap, same uid,
Maildir, ...) behind 2 Alteon with
filer (who do not permit to lock anything) to share mailboxs.
I've configured both Alteon to send same clients to same server (if
are up ;-))
cause I don't know how mutch it cost to rebuild indexes
It seem working ...
Somebody here have already to something like that ?
Do yo know the cost of an indexes rebuild ?
Thanks,
Cyril

The index rebuilding itself doesn't take hardly any time at all. Also if old indexes exist, they aren't rebuilt but rather just updated.
The biggest potential performance hit with losing indexes is losing cache file. Clients which often request the same information from mailbox (eg. mail headers) are faster if the information is already available from Dovecot's cache file so it doesn't have to open each mail separately. Webmails especially do that.
