[Dovecot] Invalid cross-device link while trying to delete folder - Dovecot 2.0.7

[Laurent CARON]

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
