dovecot - May 2012 - namespace from snapshots

hi all,

I'm trying to give access to snapshots taken from by dell iscsi MD3200i 
to my maildirs users.

snapshot are mounted in read only mode from my FreeBSD box.

In my /usr/local/etc/dovecot/conf.d/10-mail.conf, I have :

namespace inbox {
    inbox = yes
}

namespace da1 {
prefix = INBOX.backup.da1.
hidden = no
list = yes
inbox = no
location = maildir:/da1/%u/Maildir
type = private
}


I have two problems :
- In my log, dovecot complain about the fact that my snapshot filsystem 
is read only
Error: open(/da1/test2 at toto.com/Maildir/.Trash/dovecot-uidlist) failed: 
Read-only file system

The second problem is that through my thunderbird I can't see the Inbox 
saved in the snapshot (whereas I see Sent and Trash folders)

If anyone could help me, It would be nice.

Regard,
Karl.

See if http://hg.dovecot.org/dovecot-2.1/rev/7f238016db81 helps. If
you're not saving mails via dovecot-lda it might still complain if there
are new files.

Also if it complains about indexes add :INDEX=MEMORY to location.

Alternative to the patch is to add :CONTROL=~/Maildir/snapshot-control/%
u or something to location, but that could get problematic also.

It should be accessible as "INBOX.backup.da", although some older
Dovecot versions don't handle that properly.
