    7/29 Notes for the next sheriffs from aaboagye, kirtika: 
    • Major issues we are seeing, format is <Impact: Issue: Links>::
      • Tree closure, fixed now: "No space left on device" for cheets builds: aaboagye@'s post-mortem
      • CQ failures: We've been seeing intermittent failures due to hitting git fetch limits with gerrit (commit queue sync step doesn't work). The current CQ run failed due to this, would not be surprised if the next one does too.
      • Several canaries failing: Unit-test times out, possibly due to overloaded machines:
      • Android-PFQ failures: adb is not ready in 60 seconds:
    • Minor issues, work-in-progress
      • Android-PFQ: mmap_min_addr not right on samus/x86:
      • Paygen/signing issues.
      • Autoupdate-rollback (likely network SSH issue): example

    2016-07-25 thru 2016-07-29
    Sheriff: aaboagye, kirtika, hidehiko (non-PST)

    • PST
      • Canaries
        • kevin-release was broken, but a fix is on the way. (wfrichar@ knows)
      • CQ
    • Non-PST:

    • PST
      • Canaries
        • Still seeing the error in the unittest phase. See
        • Paygen issue still affecting some canaries (x86_alex-he -
        • Saw a failure with auron_yuna canary with an error parsing a JSON response. See
        • samus failed with platform_OSLimits Found incorrect values: mmap_min_addr. Filed
      • CQ
        • Closed the tree because the CQ would just reject people's changes because of the no-disk-space error.
      • Chrome PFQ
        • Still seeing some failures in the login_CryptoHomeIncognito test. See
    • Non-PST
      • CQ:
        • RED.
        • samus-paladin is failing due to no-disk-space error.
        • cheets tests are failing two times with actual error ( Being fixed.
      • Chrome PFQ:
      • Android PFQ:

    • PST
      • Canaries
        • Seems like nearly all the canaries failed during HWTest stage apparently due to Infra issues.
      • CQ
        • On one run, some of the paladins failed during the CommitQueueSync step due to git rate limiting.
      • Android PFQ
        • An overloaded devserver is causing provisioning to fail for cyan-cheets-android-pfq and veyron_minnie-android-pfq (wolf-tot-paladin too).
    • (Non-PST)
      • CQ:
        • Master paladin looks flaky due to various reasons.
          • CQ limit hitting
          • HWtest time out
          • kOmahaErrorInHTTPResponse: looks a tracking issue. 
        • These look not always reproducible, and some runs pass successfully.
      • Chrome PFQ:
        • Finally passed at #3175.
      • Android PFQ:
        • Failing in latest several runs. Though the reasons are variety. Looks just too flaky.

    7/26 (18:20 PST)
    • Canary Failure Classification: Lots of canary failures (~50%) this afternoon, so listing unique causes here to track down tomorrow: 
      • x86-zgb: Pool-health issue, infra (kevcheng@) looking into it, may be back up next canary run? 
      • x86-mario: Not sure if the manifestversionedsync is a real issue or not, filed anyway. 
      • Paygen failures: falco, falco_li, gru, jecht, kip, lumpy, ninja, parrot, peppy, samus, smaug, x86_alex-he, stumpy. TBD: Update more details here. 

    • (PST)
      • Canaries
        • Still some errors on nyan_blaze and nyan_kitty caused by the vboot_firmware CL.
          • Fixes posted to gerrit and making it's way through the CQ.
        • Still some unittest failures. There's a CL that just landed to reduce the parallelism. Will be following to see if the situation improves.
          • That CL did not seem to resolve the issues.
        • Saw a few canaries yesterday (celes this morning) that had issues when uploading debug symbols. dgarret@ is working on a fix.
        • security_StatefulPermissions is pretty flaky, veyron_minnie canary failing on it. wmatrix is all red: Investigating
        • There was canary failure on lars-release which reported all the DUTs in the pool as dead, but they seem to be up now.
        • x86-zgb pool health is poor - most devices down. kevcheng@ taking a look.
        • Towards the end of the day, a larger number of canaries were failing at the paygen step. I think what may be happening is network flakiness, but I wonder why we don't just retry again?
      • CQ
        • panther_embedded-minimal-paladin has been down for quite some time now. Pinged the bug to see if there are any updates.
          • A restart of the master has been scheduled. Need to check back later today if that fixes things.
        • No elm devices in pool:cq making elm-paladin fail. kevcheng@ taking a look. No bug yet. 
      • Android PFQ 
        • harmony_java_math CTS test is causing failures with its causing android-pfq failures "cts test does not exist".  Filed b/30413761. Ping ihf@ if it doesn't get better. 
      • Chrome PFQ 
    • (Non-PST)
      • Canaries
        • platform_FilePems issue was fixed by yusukes@.
        • Investigated a bit more about UnitTest failure. Not yet reached to root cause.
      • CQ
        • Looks flaky: Sometimes failing ErrorCode=37 (OmahaErrorInHTTPResponse).
      • Chrome PFQ:
        • Looks flaky. Sometimes failing due to login error, but there is variety of failing boards.

    • Canaries
      • Several of the canaries were failing in the platform_FilePerms HwTest.
        • This was seen on cyan, elm, lulu, oak, samus, and veyron_minnie.
        • Appears to be missing expectations for ARC containers.
        • Filed
      • The unittest stage seems to be timing out somewhat fairly often now.
      • nyan-big is failing on a vboot_firmware CL not building. Filed Fix is in CQ now. 
    • CQ 
      • Generally okay today. There was one issue regarding a failure in VMTest, but that was caught.

          More detailed notes on our shift are here.

          Stuff that broke and was fixed:
          • Lots of other release builders failing with "timed out", "didn't start", or on Sync-Chrome on Friday.  dgarrett@ said the release builders are being reorganized and will be highly unreliable.  Cleared up over the weekend.
          • CQ failed on multiple paladins HWTest with two types of failure, but both seem to have the same underlying cause in the logs.  Filed 610000 and throttled tree.
            • [bvt-inline] - logging_CrashSender: retry_count: 2, FAIL: Simple minidump send failed
            • [bvt-cq] - logging_UserCrash: FAIL: Did not find version 8288.0.0-rc2 in log output
            • Cause: CL 342574 (fixed)
          • [bvt-cq] - graphics_Gbm: FAIL: Gbm test failed().  Bad CL has been identified and fixed.
          Stuff that's still broken:
          • veyron_rialto-release fails: BuildPackages: Cannot find prebuilts for chromeos-base/chromeos-chrome.  (590784)
          • stout-paladin builder (build126-m2) is offline (609682)
          • daisy_skate-release - AUTest misconfigured (610088)
          • CQ failed with CommitQueueSync errors on multiple paladins (server hung up unexpectedly), but passed on the next run.  Seems to happen in the afternoon.

          Redirects to log files are now working again.  No more hand-modifying urls :).

          • CQ
            • There is an ongoing provisioning error (598517) that's hitting the CQ with the error: FAIL: Failed to install device image using payload athttp:// on chromeos4-row7-rack13-host11. SSH reports a generic error (255) which is probably a lab network failure.  It is still under investigation.  I think that I saw it at least 5 times during my sheriffing shift.
            • veyron_speedy had failed three times, twice with a provisioning error: "Update failed. Returned update_engine error code: ERROR_CODE=49, ERROR_MESSAGE=ErrorCode::kNonCriticalUpdateInOOBE. Reported error: AutoservRunError". This is a known issue: 600737.
            • veyron_minnie-cheets failed with a timeout error.  I checked the individual tests in the suite and they seemed to all pass (nothing aborted).  I contacted the deputy and he added more DUTs to the pool for minnie to hopefully rectify this situation.
          • PFQ
            • HWTest and VMTest failures on daisy_skate and lumpy possibly caused by dev tools regression: 601533
            • veyron_minnie-cheets failed with the same timeout error described above.  Hopefully the additional DUTs will resolve this situation.
            • cyan-cheets failed 6/8 runs due to timeouts.  There were many jobs aborted so it seems that there was a significant shortage of machines for this platform.  Infromed the deputy and he increased the allocation of DUTs from 6 to 11.
          • Canaries
            • The canaries look sad.  About half are failing for various reasons below:
              • Timeouts: ivybridge (during paygen), rambi-c (during paygen), rambi (during buildpackages), strago-b (this is due to cyan-cheets, which just upped its allocation), veyron (during paygen)

          Sheriff: shchen, adlr

          Log files are still broken.  Workaround described in b/27653354.  Solution is take and append test name to it.  
          • CQ
            • 601224:  buildpackages error on glados, strago, cyan-cheets.  Error in iwl7000 wireless driver.  The merge has been reverted.
              • So apparently merges do not show up in the change list on the builder pages.  I had an instance where a merge occurred (without me knowing) and I could not figure out what was causing the error from the waterfall pages.  It was in the kernel code, but there was only 1 kernel CL that was unrelated.  What I ended up having to do was find the hash used for the build.  It looks like:

                <project name="chromiumos/third_party/kernel" path="src/third_party/kernel/v3.18" revision="b850f41a01164fe1eb4cf76b5178194d53394130"/>

                and matching that up with a commit in 
            • whirlwind has failed three times in a row with jetstream test failures.  Deputy is trying to track down the error at 593404.  This problem seems to have been fixed.
            • cyan-cheets is failing due to a timeout: "ERROR: Timeout occurred- waited 13461 seconds, failing. Timeout reason: Slave reached the timeout deadline set by master."
              • Dug into log and seems like the provisioning stage never connected to the machine because it was down.  Checked on state of machine in the lab and it seems to be up and running again.  Will keep an eye on the test to make sure that it doesn't happen again today/tomorrow.
                • To find error, go to the cyan-cheets builder and click on last build, in this case #37.  Scroll down to the test (HWTest) and click "link to suite", which will take you to the Autotest results.  Here you find the Failed job and click on that test, which then you can find the logs to search through.
                • Currently, the log redirect links are failing, so you need to get to them with the instructions in the Notes above.  Take the test name (found in parenthesis next to the job name) and append to the link above.  So, you'll end up going to:  You'll see a folder for the hostname of the machine.  The logs are in <hostname>/debug/.
                • To check status of host, click on the hostname (to the left of the currently broken log links).  This will take you to the host's page and you can check the status of it there.
          • PFQ
            • veyron_rialto is failing with "ERROR: Cannot find prebuilts for chromeos-base/chromeos-chrome on veyron_rialto"

          To next sheriff(s):
          !! There's an issue where trying to get the logs from a test suite returns "Not Found". See b/27653354 for more details. !!
          I expect the lakitu incremental builders to both go green once CL:337302 lands.
          Canaries will probably fail due to timeouts (it's a known issue), but check the slave builder for any non-timeout related failure like Paygen or AUTest.
          PFQs should go green since the DUTs were repaired or replaced. Watch 598517 for updates regarding the generic SSH errors.
          amd64-generic-asan will continue to fail until this CL lands.
          • CQ
            • The link paladin failed during the provision step with an error that says "provision: FAIL: Failed to install device image using payload. It appears to be an update_engine error with an error code of "kNonCriticalUpdateInOOBE".
          • PFQ
            • Yesterday the PFQs were green, but today there seem to be some issues present.
            • There at least two different issues here that both occur during the provision step:
              • "SSH reports a generic error (255) which is probably a network failure" ->
              • "Update failed. The priority of the inactive kernel partition is less than that of the active kernel partition." ->
          • Canaries
            • Previous runs of the canary builders were still timing out. There was also one run where they just failed to start, but the timeout issues are still prevalent.
            • Towards the end of the day,  powerwash issues surfaced for beltino-a, jecht, and rambi canaries. ->
          • Incremental
            • Since build #7794, the lakitu-incremental builder has been failing VMTest for the test logging_UserCrash.
              • Since it was an autotest failure, searching for the string "END FAIL" in the stdio, leads to the error message pretty quickly.
              • Filed
              • This seemed to be caused by an inadvertent change due to rebasing and patch shuffling. Unfortunately wasn't caught by the CQ since the CQ doesn't run VMTests.

          This morning there were a bunch of paladin failures, with the CQ master failing 26(!) consecutive times. Because of this I throttled the tree because there's no use in trying new changes until we get the CQ actually finishing correctly.
          • Guado moblab is one of the main offenders. To get to the debug logs, I clicked on one of the failed builds, scrolled to the HWTest section, clicked on "Link to suite".
            • Once there, I clicked on the failed test, provision. (Shows up in a purple box) Then on the new page that opened, clicked on "view all logs".
            • From there, navigated to the debug directory and took a look at "autoserv.DEBUG".
              • Searched until I found the string "Autotest caught exception when running test". Just above that line, it shows the command that was attempted. In this case it was "/tmp/stateful_update: Permission denied".
            • Filed
              • The infrastructure teams notes that it's helpful to include the hostname in the bug as well. The hostname of the DUT and the buildslave.
          • daisy-full failed SimpleChromeWorkflow. The buildslave also appears to be offline since last friday.
            • To find the logs, I clicked on the failed build, and clicked the "stdio" link under SimpleChromeWorkflow. Scrolled down to find the traceback && STEP_FAILURE.
            • Looks like a couple different errors: a read-only filesystem, and an ImportError for no module named apport.fileutils.
            • Filed
          amd64-generic-asan has been failing for a _very_ long time. I found where some progress is being made. The primary CL is still pending review.

          For triaging canary failures, I first take look at each release group. Most of the failures seem to be due to the suite timing out. However there are a few other issues. You can check these by viewing the "stdio" link under step that's yellow or red.
          In the afternoon, the internal waterfall seemed dead. Infra deputy filed to a trooper.

                  • It's actually a different error, but similar error string. Fix is in CL:317780.

I honestly believe that he is a victim of VMTest in this, like the rest of us, and that we need to examine the (non)role of unit tests in diagnosing the test framework vis a vis tree closures:
                                                                                                                                                                                    • In case that's not clear, let me bluntly say that a chrome failure from a passed test should not be a tree closer.
