[Dovecot] Still virtio problems

[Erich N. Pekarek]

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 at mydomain): Error: fstat(/var/vmail/mydomain/test/.quotausage.lock) failed: No such file or directory
May 27 12:54:51 host dovecot: imap(test at 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 at 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
