i found a bug in cnfsstat [at least] in the latest BETA snapshot with the
reporting of size & position. there is a fix here, but i dont know perl, and
though it seems to work empirically, i dont know if i opened up another
problem or not (quick hack)
$ cnfsheadconf -c BUFFER
Buffer BUFFER, len: 2048.00 Mbytes, used: 611.10 Mbytes (29.8%) 1 cycles
Meta , order: 0, current: TRUE

$ cnfsstat -a
Class STUFF for groups matching "*"
Buffer BUFFER, size: 0.00 kBytes, position: 0.00 kBytes 1.00 cycles

i looked at the script, and found the following lines in a subroutine called
'human_readable'
my $unit = $#name;
my $scaled = $val / $base / $factor**$unit;
while ($scaled < 1 && $unit) {
$scaled *= $factor;
$unit--;
}
debugging it showed that $scaled was getting initialized to zero
my $unit = -1;
my $oldscaled = $val / $base;
my $scaled = $oldscaled;
while ( ( $scaled > 0 ) && ( $unit < $#name ) ) {
$oldscaled = $scaled;
$scaled /= $factor;
$unit++;
}
$scaled = $oldscaled;
and get:
$ cnfsstat -a
Class STUFF for groups matching "*"
Buffer BUFFER, size: 2.00 GBytes, position: 611 MBytes 1.00 cycles
