empty logfiles in /var/log/nova/ after logrotating with logrotated

[Christian Berendt]

We're using the following logrotate script to archive the nova logfiles. Problem is, that nova doesn't write logdata after rotating the logfiles. A restart of the service is required. Please fix the logging of the nova services in the way that it's possible to archive the logfiles and to touch a new logfile.

/etc/logrotate.d/openstack-nova:
/var/log/nova/* {
    daily
    missingok
    postrotate
}

[Bernhard M. Wiedemann (ubuntubmw)]

note that the logrotate entry in top post has a serious flaw.
instead of
/var/log/nova/*
it should read
/var/log/nova/*.log

otherwise, logrotate will create backups of backups, filling up the disk at exponential growth with millions of zero-sized files.
