[Dovecot] Still virtio problems

Hello! As posted on May 27th this year, dovecot 2.1.7 does not allow for the mailstore to be located in a virtio partition. I still receive fstat()-errors on the lock files in this combination: May 27 12:54:51 host dovecot: imap(test@mydomain): Error: fstat(/var/vmail/mydomain/test/.quotausage.lock) failed: No such file or directory May 27 12:54:51 host dovecot: imap(test@mydomain): Error: file dict commit: file_dotlock_open(/var/vmail/mydomain/test/.quotausage) failed: No such file or directory May 27 12:54:51 host dovecot: imap(test@mydomain): Error: fstat(/var/vmail/mydomain/test/Maildir/dovecot-uidlist.lock) failed: No such file or directory

Config includes:  mmap_disable=yes dotlock_use_excl=no Any ideas? Thanks Erich
