Hello all,
Figured I would write and ask suggestions for a newfs I'll be doing:
The server will be running 3.1R
Running Highwinds Typhoon News Software
I have 8x17gig Baracudas
I was thinking about doing a "newfs -m0 /dev/da1s1e" etc when I noticed this
in "man tunefs"
<SNIP>
-m minfree
Specify the percentage of space held back from normal users;
the
minimum free space threshold. The default value used is 8%.
This value can be set to zero, however up to a factor of three
in
throughput will be lost over the performance obtained at a 10%
threshold. Settings of 5% and less force space optimization to
always be used which will greatly increase the overhead for
file
writes. Note that if the value is raised above the current
usage
level, users will be unable to allocate files until enough
files
have been deleted to get under the higher threshold.
<SNIP>
My questions is this.. since Typhoon makes 9 large (2gig/each) files on the
drive (not a lot of small files like INN).. does the above apply? How do you
all recommend I newfs the drive for max performance?
