dovecot - Jun 2011 - Invalid cross-device link while trying to delete folder - Dovecot 2.0.7

Hi,

I'm having the following setup.

2 datastores mounted as:
/home/
and
/data/mail2/

I have 2 namespaces:
namespace archives-baie {
  prefix = INBOX.Extra-001.
  hidden = no
  list = yes
  inbox = no
  location = maildir:/data/mail2/%u/Maildir
  type = private
}

namespace {
  inbox = yes
  location   prefix = INBOX.
  type = private
}

When trying to trash some folder from the second namespace, I get the
following error in the logs:


imap(USER): Error: rename(/data/mail2/USER/Maildir/.Archives.20112,
/home/USER/Maildir/.Trash.20112) failed: Invalid cross-device link

In my config I have:
maildir_copy_with_hardlinks = no

Do you have a clue about this issue ?

Thanks

It's Thunderbird that's trying to rename the mailbox to under Trash
instead of actually deleting it. And since Dovecot's only choice to
actually handle that would be to copy all the mails between the
storages, it instead simply fails.
