***DEPRECATED, PLEASE VISIT https://sites.google.com/a/chromium.org/dev/chromium-os/testing/moblab *** (20170714) Q. Can I access the MobLab server (for example, to trigger a job) from another machine on the network?A. Yes, after setting up SSL keys on that machine and on the MobLab server, you can trigger and manage jobs remotely.
Q. Can I access the MobLab server from a host (a machine under test)?A. Yes, this is another way to access the MobLab server. Since host and server are on the same subnet no SSL keys are needed. However, proceed with caution to avoid contaminating test results.
Q. Can I mix and match hardware platforms for hosts on the test subnet?A. Yes, you may connect different DUT/hosts to one MobLab unit. When running hostless tests (all "suites" are run hostlessly), during "Create Job" step, if you specify "Image URL/Build" by pointing to a particular type of image for a particular type of DUT, Moblab will automatically only push subtests to corresponding DUT based on "Image URL/Build" type. Q. Where can I download the latest MobLab recovery image?A. MobLab recovery images are publicly shared at gs://chromeos-moblab-public/moblab-images. Please refer to the release notes to find out the latest release. Q. How do I immaculate MobLab to restart from the beginning?A. Powerwash is a typical solution to clean up your MobLab image. Please remember that it will clean up all your local changes including boto key, shadow_config.ini, etc. 1. Enter into VT2 2. Login as root 3. # echo 'fast safe' > /mnt/stateful_partition/factory_install_reset 4. # reboot Q. How do I join the MobLab mailing list?A. MobLab has a public discussion group, moblab-discuss@chromium.org. Please use this link to join this public group. Q. How do I access the Google cloud storage bucket from a web browser? A. Browser-based access of the storage bucket is by using the URL: https://console.cloud.google.com/storage/browser/chromeos-moblab-<partner> instead of gs://chromeos-moblab-<partner> which is the path from MobLab. Q. Mob*Monitor is complaining about "devserver is unhealthy." How do i fix this?A. First check "Moblab Setup" on your upper right corner of AFE, it does an validation of your boto key and cloud storage bucket location are a match. To be double sure, you can also ssh into your moblab unit as "moblab" user, and then run "gsutil ls gs://<your bucket name>", if it displays the correct content as you would see at https://console.cloud.google.com/storage/browser/<your bucket name> from a browser, then your boto key is setup correctly. and you may ignore Mob*Monitor complain in this case. Q. Mob*Monitor is complaining about xxx service not starting, how do i fix this? A. try reboot moblab unit and see if you get a clearner Mob*Monitor analysis. if not, click "collect Logs" in Mob*monitor screen, and upload the logs to a google drive location and share it with your Google contact to investigate further. Q. I reboot my MobLab, and now i can't get to the Moblab AFE from a browser, and looks like Apache is not up, what is happening?A. One most common cause could be you are out of storage space. To confirm, go to Mob*Monitor http://localhost:9991 from your moblab unit, or http://<your moblab ip>:9991 from a remote machine on the same network. If you are out of space, Mob*Monitor will tell you. Q. Mob*Monitor says "Moblab has less than 10 percent free disk space. Please free space to ensure proper functioning of your moblab." what should i do? A: Moblab startup scripts look for a drive with at least 32 GB free or an external USB labelled MOBLAB-STORAGE. So you can either ssh into your moblab and clean up /usr/local/moblab/storage/results directory and reboot. or attach an external storage labelled MOBLAB-STORAGE and reboot. A: Moblab offloads test results every 24 hours to google cloud storage. If your network connectivity is down, the results will accumulate and if you are running long running tests, the results will build up and eat up your storage space. Q. I just received a brand new Moblab unit and trying to recover it using the latest moblab image specified by release notes. But when boot into recovery screen and plug in my usb-stick with the moblab recovery image, i'm getting "The device you inserted does not contain Chrome OS" message.A: Moblab image is a modification of Guado (ASUS Chromebox). If the unit you purchased come with Guado stock image instead of Guado_moblab, you will encounter the error you specified when you try to recovery a guado unit to guado_moblab due to the key difference. The work around is the following:
Q:My DUT kept on beeping during startup (when auto start from "verification is off" screen), it is really annoying, can i silence the DUT? A: go to VT2 (ctrl+alt+F2), log in as root, and type the following in the command line will silence the DUT $ /usr/share/vboot/bin/set_gbb_flags.sh 0x19
