[9fans] Venti on OpenBSD

[9fans] Venti on OpenBSD

[Henry Baragar]

Hello all,

I am trying to set up venti under plan9 ports (using a recent update) on an
OpenBSD 3.8 box.

I have dedicated an 80GB disk for venti arenas.  I ran the following command:

# venti/fmtarenas -a 128m isi /dev/rwd1c
part /dev/rwd1c: file /dev/rwd1c offset 0 size 80,026,361,856

This command was started several days ago and still has not completed.

Top tells me:

load averages:  2.73,  2.83,  2.92                                    08:58:19
94 processes:  2 running, 91 idle, 1 on processor
CPU states:  9.8% user,  0.0% nice, 90.2% system,  0.0% interrupt,  0.0% idle
Memory: Real: 243M/301M act/tot  Free: 196M  Swap: 0K/512M used/tot

  PID USERNAME PRI NICE  SIZE   RES STATE    WAIT     TIME    CPU COMMAND
 8089 root      64    0   24M   24M run      -       78.9H 49.41% fmtarenas
16709 root      64    0   24M   23M run      -       44.5H 47.71% fmtarenas


Should it take this long to format the arenas on an 80GB disk?

Did I run fmtarenas correctly?

Regards,
Henry

So 84 hours of CPU time is unreasonable?

Is there supposed to be two processes?

I downloaded the code a few weeks ago; I ran a cvs update and recompiled last
week.

Hello all,

I have given up on using raw partions and am trying regular files as discussed
in http://archive.netbsd.se/?ml=Plan9-9fans&a=2005-12&t=1586319.

Now I am getting a segmentation violation:

sara# cd /venti
sara# dd if=/dev/zero of=dvd_00 seek=4966055935 bs=1 count=1
sara# 9 rc
% ls -l dvd_00
--rw-r--r-- M 0 root wheel 4966055936 Jul 26 11:45 dvd_00
% venti/fmtarenas -a 128m isi dvd_00
part dvd_00: file dvd_00 offset 0 size 4,966,055,936
24824: signal: sys: segmentation violation

Is this a problem with OpenBSD or am I missing something?

Thanks,
Henry

    could you send me a stack trace from the core?
