I've tried on a fresh ubuntu but it worked, some days ago a user
reported me the same issue but after a reinstall it worked. It can be
very useful for kestrel if you can help me discovering why sometimes
fails.

If you want to fix it quicky, comment everything on /etc/dnsmasq.conf
a run again :

sudo kestrel-reconfigure --frontend.

JonAn.

Is dnsmasq starting correctly?

sudo /etc/init.d/dnsmasq restart

Or do the nodes fail during the PXE boot?

Regards,

JonAn.

Hi Jon Ander Hernandez,
when i launch

sudo /etc/init.d/dnsmasq restart

it fail.

I check also the configuration file (dnsmasq --test) but there isn't 
error...
(also the PXE boot of the node fail!)

what is wrong?

Thank you

Try reinstalling dnsmasq and testing again dnsmasq :

    sudo apt-get --purge --reinstall install dnsmasq

    sudo /etc/init.d/dnsmasq restart

If it works you can then reconfigure it with kestrel :

    sudo kestrel-reconfigure --frontend

If it doesn't work send me dnsmasq's log file :

    cat  /var/log/syslog | grep dnsmasq | grep "Jan 25" > debug.log

JonAn

I try to reinstall all.
I installed Ubuntu 10.10 i386 (is egual to x64 or is better 64bit??), 
and after reboot Iaunch this command:

|sudo apt-get install python-software-properties
sudo add-apt-repository ppa:kestrel/kestrelhpc
|

|sudo su
echo "deb http://ppa.launchpad.net/kestrel/kestrelhpc/ubuntu maverick 
main" >> /etc/apt/source.list
echo "deb-src http://ppa.launchpad.net/kestrel/kestrelhpc/ubuntu 
maverick main" >> /etc/apt/source.list
apt-get update
apt-get install |kestrelhpc kestrelhpc-openmpi kestrelhpc-ganglia

but the installation fail with this error:

/boot/dracut.img-2.6.35-22-generic-pae does not exist. Cannot update.
Si sono verificati degli errori nell'elaborazione:
  kestrelhpc
  kestrelhpc-ganglia
  kestrelhpc-openmpi
E: Sub-process /usr/bin/dpkg returned an error code (1)

How can I solve it?

Thank you

Diego

This is a warning, not an error.

Install syslinux package :

sudo apt-get install syslinux

Regards,

JonAn.

Thank you Jon!
Now I finish the installation, I created the image and now I want 
register the slave node, but it show without the mac-address and so it 
doesn't register the slave node

sudo kestrel-control --register group1

Turn now on the nodes to add them to the group "image1"

Press crtl+c when you are done

Registering node "kestrel-group1-1"
     mac :
     ip  : 192.168.30.26

Thank you a lot

I can't reproduce it here,  can you show me the last lines of the
kestrel log file?

less /var/log/kestrel-daemon.log

JonAn.

Hi Carachi,

I need to fix an issue which makes empty events which is what the log
shows (somehow I send "\n" chars to the daemon's FIFO...), but they
have no effect on the system, the interesting bits should be before
that event. :-S

Please send the whole log.

The last error is because kestrel-daemon what stopped after
kestrel-rpc (kestrel-rpc closed the FIFO...), I will fix it so it
doesn't show the message again.

Regards,

JonAn.

This is the log.

Ummm... the log is normal, but as you said the mac is empty.
It seems that there is something extrange with dnsmasq, maybe there is
something else modifying its configuration or something...

Can you check/send me this file?

    /var/lib/misc/dnsmasq.leases

And the configuration file:

    /etc/dnsmasq.conf

Regards,

JonAn.

Thank you JonAn

Tomorrow I will send you all.

a question :  Can I increase also the performace of my web server 
(apache + php) with Kestrel?

Thank you a lot
Bye

There are some plataforms which allow you to do so. But by now we only
support MPI (and in a close future Charm++). If you want we can work
together to write a Pacemaker module :
