[9fans] latest iso: venti issues

[John Soros]

Hi everyone!
I'm having a problem with the latest iso (sept. 26).
The issue is probably with venti. Here's the description:
After a fossil+venti installation, I boot up my terminal, and a venti archive snapshot is taken at once. (normal behaviour)
The unusual thing is that when it stops, the machine freezes. Though stats works fine, so I can see my cpu utilisation go down to minimal, i can't fshalt, or do anything.
Then, if I reboot my machine, the same thing happens: (probably) venti starts to archive (high CPU and hdd utilisation), then, if I let it finish, again, rio (or something) freezes, I can't fshalt, I can't run any command.

Many thanks to everyone contributing, plan9 is truly a beautiful os.

Cheers

some people on irc reported the same problem. I can reproduce it on qemu
with a normal install.
venti hangs on "sync..." after the 2nd boot.

but here is no solution yet. :-(

FWIW, I had seen the same problem earlier but everything
seemed to work fine in a qemu image built from the Sep 22
plan9.iso.bz2 (md5 = b0fb4bbd962ef73f32656b52586747b3).  The
one difference I remember from before is that this image uses
the 'qcow2' format and not 'raw'.

One issue with plan9 on qemu is that on first reboot after an
install on a brand new "disk", date reverts to an earlier
time (Jan 1 2000?) and that confuses venti it seems.  So
before I make *any* changes, I manually start the network +
dns, and restart timesync after pointing it to an ntp server.

I spoke too soon.  After a pull I see the same symptom again.

hmm, yeah, i don't really think it's the same problem.
Though if I understand well, for you venti works, does the dump on
first boot and then shuts up?
(btw. my venti freeses after sync too, at third boot)
cheers

This is *not* on qemu.

Oh, and I forgot to add that I did a fresh install, but fossil only
this time, and the problem doesn't appear, so it's definitely a venti
problem, or the problem is tied to venti.
