LAVA requires a range of singleton daemon processes to schedule, organise,
publish and log the test job operations. 2017.12 will be retiring the
lava-server daemon and the /var/log/lava-server/lava-scheduler.log, moving
those operations into the lava-master daemon and the
/var/log/lava-server/lava-master.log. This is one of the steps in the
removal of V1.
This leads a substantial change to how admins approach an instance running
2017.12 or later.
When jobs don't appear to be running for some reason, the default action is
to check /var/log/lava-server/lava-scheduler.log - once the instance is
running 2017.12 or later, admins need to remember that it is correct for:
* /var/log/lava-server/lava-scheduler.log to be empty
* the status of the lava-server daemon to be active (exited)
* the lava-server service to not restart
At some point after 2017.12 has been running, admins can choose to archive
or purge /var/log/lava-server/lava-scheduler.log* and / or disable the
lava-server service using systemctl.
The scheduler from 2017.12 onwards will consist of:
* the status of the lava-master daemon will be active (running)
* the lava-master service will restart when admins request it.
LAVA, until now, has packaged SysVinit files to manage the various daemons
but there have been longstanding problems with log rotation and the need to
carry redundant code to manage the daemonize process for python scripts.
This has allowed instances to support both SysVinit and systemd because
systemd automatically converts the SysVinit files to systemd service files.
Now that V1 has been removed, it has become possible and advantageous to
drop SysVinit support and move to only systemd support. This is expected to
mean that lava-dispatcher (and therefore lava-server) will depend on
systemd-sysv, i.e. systemd needs to be the init system to be able to start
the daemons upon which LAVA relies.
A default install of Debian Jessie and Stretch already defaults to using
systemd as the init system, so this does not necessarily involve any

2017.11 is the second release on the roadmap to the removal of V1. This is
the single largest change ever made to the LAVA packages.
* All dashboard URLs are permanently disabled in lava-server.
* All devices which were not enabled for V2 are now hidden and unusable.
* All V1 code has been removed from lava-dispatcher.
* All V1 documentation has been removed from lava-server-doc.
2017.11 disables all access to any V1 test data - including V1 only
devices. The data itself remains in the database but is not accessible via
If you have chosen to keep an archive of V1 test data and have not yet done
so, you should do this before installing this upgrade. At the very least,
you **must** have a backup of your postgresql database **before** you
upgraded to 2017.11 in order to make a V1 test data archive later.
2017.11 requires that **all** workers and each associated master are
upgraded to 2017.11 for test jobs to continue running. This is because
there have been very large changes to the directories and file layout
within both lava-server and lava-dispatcher associated with the removal of
the V1 components.
The LAVA software team have been checking ahead for the final stage of the
roadmap and plans are on track, as described.
http:// and https:// changes in django
A reminder, if you are accessing an instance using http:// (whether
localhost or not), then the changes described in the documentation **must**
be applied for the instance to operate correctly. This is a security change
in Django, not a change in LAVA.
Symptoms include HTTP500 errors but can also include the inability to login
to an instance using LDAP or local django accounts, depending on your local

2017.11 also includes large changes to the packaging of both lava-server
and lava-dispatcher. The prompts formerly used to configure a V1 remote
worker have been removed. Packaging is maintained at
Packages for 2017.11 have been uploaded to Debian unstable and also the
LAVA repositories (for jessie-backports and stretch-backports).
