[JIRA] (OVIRT-2210) VDSM CI failes on all new FC28 slaves becaose of the 'mock' GID

VDSM CI failes on all new FC28 slaves becaose of the 'mock' GID --------------------------------------------------------------- Key: OVIRT-2210 URL: https://ovirt-jira.atlassian.net/browse/OVIRT-2210 Project: oVirt - virtualization made easy Issue Type: Outage Components: CI client projects, Jenkins Slaves Reporter: Barak Korren Assignee: Evgheni Dereveanchin Priority: Highest We see all check-patch jobs for VDSM failing when running on the new FC28 slaves, with an error like the following: {code} ERROR: Command failed: # /usr/sbin/groupadd -g 1000 mock {code} The reason for this issue is that mock tries to have the 'mock' group have the same GID inside and outside of the mock environment. In the case of the new slaves the GID for the 'mock' group is 1000. Since 1000 is the 1st GID you get of you run 'groupadd' the probability of it colliding with any GID created by a package inside the 'mock' env is quite high. In the case of the VDSM CI, the GID 1000 is taken by the 'openvswitch' package for the 'hugetlbfs' group. This on its own is a bug because no package should be taking GIDs beyond 1000, but having said that, the CI should not break on this, so we need to move the mock GID to below 1000 to a number that is unlikely to collide with others. In the meantime all fc28 slaves will be disabled.
