EL8 builds fail to mount loop device - kernel too old? ------------------------------------------------------

Key: OVIRT-2813 URL: https://ovirt-jira.atlassian.net/browse/OVIRT-2813 Project: oVirt - virtualization made easy Issue Type: By-EMAIL Reporter: Nir Soffer Assignee: Barak Korren

I'm trying to run imageio tests on el8 mock, and the tests fail early when trying to create storage for testing: [userstorage] INFO Creating filesystem /var/tmp/imageio-storage/file-512-ext4-mount Suggestion: Use Linux kernel >= 3.18 for improved stability of the metadata and journal checksum features. [userstorage] INFO Creating file /var/tmp/imageio-storage/file-512-ext4-mount/file [userstorage] INFO Creating backing file /var/tmp/imageio-storage/file-512-xfs-backing [userstorage] INFO Creating loop device /var/tmp/imageio-storage/file-512-xfs-loop [userstorage] INFO Creating filesystem /var/tmp/imageio-storage/file-512-xfs-mount mount: /var/tmp/imageio-storage/file-512-xfs-mount: wrong fs type, bad option, bad superblock on /dev/loop4, missing codepage or helper program, or other error.

Same code runs fine in Travis: https://travis-ci.org/nirs/ovirt-imageio/jobs/595794863 And also locally on Fedora 29: $ ../jenkins/mock_configs/mock_runner.sh -C ../jenkins/mock_configs -p el8 ... ## Wed Oct 9 23:37:22 IDT 2019 Finished env: el8:epel-8-x86_64 ## took 85 seconds ## rc = 0 My guess is that we run el8 jobs on el7 hosts with old kernels (Suggestion: Use Linux kernel >= 3.18 for improved stability of the metadata and journal checksum features.) This issue will affects vdsm, using similar code to create storage for testing. For vdsm the issue is more tricky, since it requires same host/distro: 49 - tests-py37: 50 runtime-requirements: 51 host-distro: same So I think we need: - make slaves with newer kernel (fc29? fc30?) with the el8 mock env - add el8 slaves for running el8 mock with "host-distro: same" If we don't have a solution we need to disable el8 tests, or continue testing without storage, which will skip about 200 tests.
