Yes. I could, but a reasonable hypothesis is that fossil
issue
a lot of requests caused by a venti unexepected behaviour.
Probably the install procedure is ok.
Could it be an endless backup due to a wrong (interpretation
of the)
sys clock ?

About 1. 2. and 3. I've no precise info now. The CPU is
mainly used by fossil/venti and the load is high enough to
freeze
rio almost totally (the mouse cursor moves every 5-6 sec on
a P3000).
Have been used PCs very different in age/disks/ram etc,
always with the same result.

Usually, just after the first boot, there is a strong disk
activity
only for a few minutes and with a reasonable rio response.
After that
the system get idle it is possible proceed with the
configuration. 

This is exactly the behaviour with all the other ISOs,
included
the one downloaded on Jan-07.

In all tests has been repeated exactly the same "default"
install
procedure without seeing any message error.

On Dec 27 I wrote about a problem I had installing a
fossil+venti config using the ISO image downloaded on Dec
22:

* On several HW setup, from P500 to P3000, the
* install goes ok but just after the boot from HD
* starts an endless activity (> 20 h ?!) with a steady
* 100% cpu load and periodic (1 sec seek, 3 sec. pause)
* disk load. Then the machine hangs.

The same behaviour has also been observed in the University
lab by some students working on a thesis about Plan9.

Is there other 9fan(s) who had the same problem ?

Hi, all.

I'm trying to install a fossil+venti file server using
the ISO dowloaded on Dec 22.

On several HW setup, from P500 to P3000, the
install goes ok but just after the boot from HD
starts an endless activity (> 20 h ?!) with a steady
100% cpu load and periodic (1 sec seek, 3 sec. pause)
disk load. Then the machine hangs.

Absolutely no problems on the same HW configurations
with the 16-Jan-07 ISO.

Any ideas ?

Thanks in advance.
