Hallo Mark,
I was able to pinpoint the problem but my perl knowledge is too limited
to provide a fix.
In line 1642 of /usr/sbin/apt-cacher the check is done, and for that
$statfs->{used} + (new-content-file) is checked against the
configuration. $statfs->{used} is set via df($cfg->{'cache_dir'}, 1)
However, http://search.cpan.org/~iguthrie/Filesys-Df-0.92/Df.pm
tell however, that
"{used} = Total blocks used on the filesystem."
and not the total blocks used in the given directory.
With that read i modified the info message to give me also
info_message('ALARM: ' . $statfs->{used} .' Insuffient space for
Content-Length: '.
$response->header('Content-Length').
' in cache_dir with ' . $statfs->{bavail} . ' available space');
and I get
Tue Oct 9 18:59:05 2012|info [16035]: ALARM: 161367425024 Insuffient
space for Content-Length: 48398 in cache_dir with 58364964864 available
space
This pretty much matches du -sb /srv and I think this is the reason why
this check fails.
When using the perl line you submitted, I can confirm that the result is
independent of the directory given as argument.
