Fine with me, but then please add to the page a link somewhere to the list
of possible commands.
I commented "Rerun-Hooks: all" tens of times so far, and in each and every
one of them had to search for the exact syntax - never managed to memorize
it.

eyal edri [Administrator] commented on OVIRT-920:
-------------------------------------------------
We might be able to do it but not with a button, but with a comment, similar to what GitHub has ( for e.g in Lago we do "ci test please" to run a job on PR ).
This still needs checking, but it might be possible via adding new 'build-artifacts-from-patch.sh' script added to standard CI which will run the same code as build-artifacts
(it can symlink to the build-artifacts if there is no diff between it to normal build-artifacts) and the trigger for it will be done by typing a comment in the patch,
something like "jenkins please build".
We'll implement it by adding a yaml patch with new template for the gerrit trigger plugin with the 'comment added contains regular expression' option.

Hi,
I think it will be useful to have an option to very easily (such as
pressing a button in gerrit) to do a full build of a project,
similarly to current build-artifacts, but for a pending patch - so it
will not be collected by any publisher, and will keep its artifacts
for a short time (say, 2 days).
This will allow to use these artifacts for manual tests, perhaps
longer than check-patch, in case a developer wants to do them.

[JIRA] (OVIRT-919) Fwd: CI slaves extremely slow - overloaded slaves?

{quote}
[~nsoffer(a)redhat.com] Lets make sure we're comparing apples and apples first, did you run this using "{{mock_runner.sh}}" on your laptop? Perhaps try this in a VM on your laptop?
{quote}
It seems that we are overloading the CI slaves. We should not use nested kvm
for the CI, such vms are much slower then regular vms, and we probably run
too many vms per cpu.
{quote}
Not sure where nested kvm comes into play here, "{{check_patch.sh}}" runs on plain VMs.
(As an OT side-note: Are you sure nested VMs should be slower CPU-wise? AFAIK those are just VMs with nested I/O routing... it may be interesting to check this with Lago...)
WRT "overloaded slaves" - that can hardly happen, no slave ever runs more then one job at at time.
The hypervisors themselves may be loaded, we'll try to gather some more data here:
[~ngoldin(a)redhat.com] Do we have hypervisor load graphs in Graphite?
[~ederevea] What is out vm/core ratio? Are we running oVirt DWH? maybe it can help us here...
{quote}
We can disable such tests in the CI, but we do want to know when there is
a regression in this code. Before it was fixed, the same test took 9 seconds
on my laptop. We need fast machines in the CI for this.
{quote}
As far as machines go, our upstream hardware is quite beefy these days, so lets not jump to any conclusions. More data is needed, what is this test actually doing? is this pure CPU, or is there so I/O involved here as well?
[~rgolan(a)redhat.com] Are there any oVirt features that can help us here? Higher priority VMs? Realtime? Better scheduling?

It seems that we are overloading the CI slaves. We should not use nested kvm
for the CI, such vms are much slower then regular vms, and we probably run
too many vms per cpu.
We can disable such tests in the CI, but we do want to know when there is
a regression in this code. Before it was fixed, the same test took 9 seconds
on my laptop. We need fast machines in the CI for this.

Hi all,
In the last weeks we see more and more test failures due to timeouts in the CI.
For example:
17:19:49 ======================================================================
17:19:49 FAIL: test_scale (storage_filesd_test.GetAllVolumesTests)
17:19:49 ----------------------------------------------------------------------
17:19:49 Traceback (most recent call last):
17:19:49 File
"/home/jenkins/workspace/vdsm_master_check-patch-fc24-x86_64/vdsm/tests/storage_filesd_test.py",
line 165, in test_scale
17:19:49 self.assertTrue(elapsed < 1.0, "Elapsed time: %f seconds"
% elapsed)
17:19:49 AssertionError: Elapsed time: 1.105877 seconds
17:19:49 -------------------- >> begin captured stdout << ---------------------
17:19:49 1.105877 seconds
This test runs in 0.048 seconds on my laptop:
$ ./run_tests_local.sh storage_filesd_test.py -s

storage_filesd_test.GetAllVolumesTests
