** Description changed: - This is a scripted bug report about ADT failures while running zfs-linux - tests for linux-hwe-5.4/5.4.0-79.88~18.04.1 on bionic. Whether this is - caused by the dep8 tests of the tested source or the kernel has yet to - be determined. + == zfs-linux SRU == + + IMPISH, HIRSUTE, GROOVY, FOCAL, BIONIC, XENIAL + + [Impact] + + The zfs debian scrub test sometimes times out on slower test systems + because scrub can take a while to complete and the scrub test can + time out. The test needs some more intelligence to detect this + and a longer time out for slower systems. + + The fix now polls the scrub completion more thoroughly and increases + timeout to 15 minutes. + + [Test Plan] + + Run the test with autopkgtest on slow file systems. With the fix the test + has longer timeout and will pass rather than fail with a timeout. e.g. + + autopkgtest zfs-linux_2.0.3-8ubuntu5.dsc -- null + + + [Where problems could occur] + + The timeout is hard coded to 15 minutes. This should be enough for slow + devices with the small ZFS volume set used by this test. However, it may + still fail if the backing store is really slow. However, we don't want the + test to be blocked indefinitely waiting for a timeout, so a 15 minute + scrub timeout seems to be long enough to be more than reasonable. Any longer and it's highly likely that the scrub has hung. + + [Other Info] + + This test is almost identical to the same scrub test run from the kernel + team autotest zfs smoke test, so it has been exercised regularly and is + known to reliably. + + ------------------------------------------------------------------------- + + + This is a scripted bug report about ADT failures while running zfs-linux tests for linux-hwe-5.4/5.4.0-79.88~18.04.1 on bionic.

However, the ADT tests don't use autotest, the test script run comes from the zfs-linux dkms source package, debian/tests/kernel-smoke-test-scrub.
