Roadmap reminder ================
https://lists.linaro.org/pipermail/lava-announce/2017-September/000037.html
Installing 2018.1 will apply the changes from 2017.12 and earlier to **permanently erase V1 test data** if this has not been done already. (i.e. if you skipped installing 2017.11 or 2017.12, remember that 2018.1 includes the changes of 2017.11 and 2017.12.)
Removal of V1 test jobs =======================
A few provisos with this release - there are a lot more changes to the lava-server package than to the dispatcher because 2018.1 drops the old lava_scheduler_daemon app and moves all scheduling into lava-master.
The new scheduler state machine involves some database migrations:
Applying lava_scheduler_app.0032_add_state_health_to_testjob_and_device... OK Applying lava_scheduler_app.0033_remove_old_status_fields... OK Applying lava_scheduler_app.0034_worker_last_ping... OK
If your instance has a lot of V1 test jobs still, the migration could timeout, so as the final part of the removal of V1, follow the guidance in the documentation to remove V1 test jobs, if you have not already. (By "a lot", we're thinking more than a few thousand.)
https://validation.linaro.org/static/docs/v2/v1removal.html#removing-v1-file...
If you have millions of V1 test jobs (as validation.linaro.org had), you will need to stagger the removal of the V1 test jobs using the --older-than support. Talk to us if you have issues, there is an updated script which we used on validation.linaro.org but that would need to be locally cherry-picked from 2018.1 onto the system running 2017.12.
The removal script can be interrupted with Ctrl-C and restarted if required. Depending on the performance of the host machine, it may take a long time to run the removal, up to several hours in some cases.
Finally on the removal of V1 test jobs, the support removes not just the database object but also the log file directory, so your master should find a lot more usable fileystem space has appeared, once complete. In many cases, the log file directory can be missing for a V1 test job but the warning is just for information. The database object will have been removed.
Removal of unwanted dependencies ================================
$ sudo apt-get --purge autoremove
Do check the list of packages before proceeding. If there are packages which you need for local support, make sure those packages are marked as "manually installed" in apt by using apt-get install <package_name> (this doesn't reinstall an existing package, it simply marks it as not a candidate for autoremove).
It is worth running autoremove after this release has been deployed, extra dependencies can still be a security problem and an admin burden.
Stretch =======
2018.1 *deprecates* Debian Jessie and moves the recommendation on to Debian Stretch as the supported OS for LAVA.
https://lists.linaro.org/pipermail/lava-announce/2018-January/000046.html
Note that when the instance is upgraded to Stretch, this will bring in a new major version of PostgresQL and your LAVA database will need to be *manually* migrated. Neither PostgresQL nor Debian will do this for you.
https://validation.linaro.org/static/docs/v2/debian.html#migrating-postgresq...
When following this guide, remember that your versions will differ from the guide - typically for the upgrade to Stretch, you will be migrating from 9.4 to 9.6. Take care with the commands to ensure you drop and upgrade the correct cluster. Make sure you have a valid backup. The instance will need to be in a *maintenance window* for the migration to occur.
Repositories ============
2018.1 has been uploaded to stretch-backports and jessie-backports for the production-repo on images.validation.linaro.org and jessie-backports will continue to receive updates until we get closer to the end of security support for Jessie.
