Re: [ovirt-devel] [VDSM] All tests using directio fail on CI

The CI setup did not change recently.

All standard-CI jobs run inside mock (chroot) which is stored on top of a regular FS, so they should not be affected by the slave OS at all as far as FS settings go. But perhaps some slave-OS/mock-OS combination is acting strangely, so could you be more specific and point to particular job runs that fail?
