[ovirt-devel] Re: EL8 builds fail to mount loop device - kernel too old?

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.

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.)

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.
