Jan Schlicht commented on MESOS-5236: ------------------------------------- It fails every time. Pretty sure because it an early version of the {{overlayfs}} module. To reproduce, use Ubuntu 14.04. That should have Kernel 3.13. In that version, {{overlayfs}} wasn't yet merged into the kernel, but Ubuntu nevertheless provides an early version of it. You can enable it with a {{sudo modprobe overlayfs}}. > OverlayBackendTest.ROOT_OVERLAYFS_OverlayFSBackend test flakiness > ----------------------------------------------------------------- > > Key: MESOS-5236 > URL: https://issues.apache.org/jira/browse/MESOS-5236 > Project: Mesos > Issue Type: Bug > Reporter: Neil Conway > Assignee: haosdent > Labels: flaky, flaky-test, mesosphere > > Observed on internal Mesosphere CI: > {noformat} > [13:31:06] : [Step 10/10] [ RUN ] > OverlayBackendTest.ROOT_OVERLAYFS_OverlayFSBackend > [13:31:06]W: [Step 10/10] I0419 13:31:06.708961 23289 overlay.cpp:161] > Provisioning image rootfs with overlayfs: > 'lowerdir=/tmp/Dkgh5V/source2:/tmp/Dkgh5V/source1,upperdir=/tmp/Dkgh5V/scratch/rootfs/upperdir,workdir=/tmp/Dkgh5V/scrat\ > ch/rootfs/workdir' > [13:31:06] : [Step 10/10] > ../../src/tests/containerizer/provisioner_backend_tests.cpp:97: Failure > [13:31:06] : [Step 10/10] (backends["overlay"]->provision( {layer1, > layer2}, rootfs, sandbox.get())).failure(): Failed to mount rootfs > '/tmp/Dkgh5V/rootfs' with overlayfs: No such device > [13:31:06] : [Step 10/10] [ FAILED ] > OverlayBackendTest.ROOT_OVERLAYFS_OverlayFSBackend (5 ms) > {noformat} -- This message was sent by Atlassian JIRA (v6.3.4#6332)
