Imaging - Davos Debug

Launch Davos, then press CTRL+C

From here, there are two options: Local connection or SSH

Local connection:
# in the Davos console
sudo su
dpkg-reconfigure keyboard-configuration
systemctl restart keyboard-setup
python3

SSH connection:
First, retrieve the machine's IP address, then from the relay server:
ssh user@<IP>
 Password: live
sudo su
python3

  • To register the machine:
from davos import davosManager
from davos.inventory import Inventory

davos = davosManager()
inv = Inventory(davos)
#
# Enter the hostname in the input
# this will send the XML to pulse2-register-pxe

print("mac address: {}".format(inv.macaddress))
print("ip address: {}".format(inv.ipaddress))
print("netmask: {}".format(inv.netmask))
print("disk : {}".format(inv.disk)) 

# The inventory (unmodified) is located in:
less /tmp/inventory.xml
# There must be a missing / between tmp and macaddress, causing the file to be generated in /
/tmp<macaddress.xml

  • To debug the backup 
from davos import davosManager
from davos.image_saver import imageSaver

davos = davosManager()
saver = imageSaver(davos)
saver.start()
Save the backup:
saver.imaging_api.imageDone(saver.manager.mac, saver.image_uuid)

  • To debug the restore:
from davos import davosManager
from davos.image_restorer import imageRestorer

davos = davosManager()
img = imageRestorer(davos, "unicast")
To start a full restore:
img.start()
To run only the post-installs
img.run_postimaging()
The Davos logs are located in:
/var/log/davos.log
/var/log/davos_restorer.log

The post-install logs are located in:
/tmp/postinst.xxx.log

Postinstalls are located in /imaging_server/masters/<master_uuid>/postinst.d/
 The master UUID can be retrieved from the imaging.Image table in the database.
