Evgheni Dereveanchin commented on OVIRT-910:
--------------------------------------------
[[email protected]] some logs would be helpful :)
Older slaves with local disk hook use ext4 on the secondary disk while newer
ones write to rootfs which is XFS. I can try launching a dozen ext4 VMs so that
we can compare performance.
> mock_runner.sh seems to run slower on newer slaves

> Key: OVIRT-910
> URL: https://ovirt-jira.atlassian.net/browse/OVIRT-910
> Project: oVirt - virtualization made easy
> Issue Type: Improvement
> Components: Jenkins
> Reporter: Barak Korren
> Assignee: infra
>
> After implementing speedup improvements for mock_runner.sh (Specifically
> enabling it to deploy the chroot by extracting a tarball as opposed to
> installing it with yum every time), I started monitoring run times for vdsm
> check_patch jobs.
> I've noticed that jobs that are running on the old slaves (fc24-vm*) seem to
> initialize mock faster then ones running on new slaves (vm*) - 17seconds vs
> 57 seconds respectively.
> I suspect this may be because the older slaves have a different FS mounted on
> /var/cache/mock
