dovecot - Jul 2005 - 1.0-stable and nfs

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
