Subject: [9fans] venti on linux under p9port?

I'm trying to muddle my way through creating a venti under p9ports on a
linux box (for various reasons).  For the moment, I'm not too concerned
at performance, I just want to get familiar with it.  Rather than
accessing a raw partition, I'm trying to set it up to refer to arena and
index files in /usr/local/venti (is this sensible?)

So far:

Created the arena files from sh with:

dd if=3D/dev/zero of=3Darenas1 seek=3D$((1024 * 1024 * 512 - 1)) bs=3D1 c=
ount=3D1

Created the index files with:

dd if=3D/dev/zero of=3Disect0 seek=3D$((1024 * 1024 * 24 - 1)) bs=3D1 cou=
nt=3D1

Then following the wiki page on setting up venti:

Format the arenas with:

% venti/fmtarenas arenas0 /usr/local/venti/arenas0
fmtarenas /usr/local/venti/arenas0: 1 arenas, 536,076,288 bytes storage,
524,288 bytes for index map

% venti/fmtarenas arenas1 /usr/local/venti/arenas1
fmtarenas /usr/local/venti/arenas1: 1 arenas, 536,076,288 bytes storage,
524,288 bytes for index map

Format the index sections with:

% venti/fmtisect isect0 /usr/local/venti/isect0
fmtisect /usr/local/venti/isect0: 2,975 buckets of 215 entries, 524,288
bytes for index map
% venti/fmtisect isect1 /usr/local/venti/isect1
fmtisect /usr/local/venti/isect1: 2,975 buckets of 215 entries, 524,288
bytes for index map

% cat venti.conf
  # the name of the index
  index main

  # the index sections
  isect /usr/local/venti/isect0
  isect /usr/local/venti/isect1

  # the arenas
  arenas /usr/local/venti/arenas0
  arenas /usr/local/venti/arenas1

Problem comes when I try to start venti, it just gives me the following:

% venti/venti -w
usage: venti [-dsw] [-a ventiaddress] [-h httpaddress] [-c config] [-C
cachesize] [-I icachesize] [-B blockcachesize]

I can't seem to work out any combination of parameters that give any
output other than the above.

Any assistance, or which fine manual have i missed?

thanks,

	ADrian
