[LU-12870] sanity-hsm test 9A fails with “uuid Dumping not found in agent list on mds1”

Related — Thu, 22 Oct 2020 13:46:57 +0000

sanity-hsm test_9A fails with multiple errors for Ubuntu client testing . Looking at results starting 01 APRIL 2019, this test fails 100% of the time for Ubuntu 16.04 and ~73% of the time for Ubuntu 18.04. For master, this test fails 100% of the time since April. For b2_12, it looks like something bad landed on or before 02 JULY 2019 with Lustre version 2.12.2.69 because we have 100% failure of this test from this date until today; failures start with test session https://testing.whamcloud.com/test_sets/86cbddd4-9e26-11e9-8fc1-52540065bddc.

When sanity-hsm test 9A fails, we see about 50 or more other sanity-hsm tests fail and, in all cases, eventually a later test will time out; see https://testing.whamcloud.com/test_sets/c3676bb2-eb26-11e9-b62b-52540065bddc or https://testing.whamcloud.com/test_sets/a8bded48-5db6-11e9-92fe-52540065bddc .

Looking at the suite_log for https://testing.whamcloud.com/test_sets/c3676bb2-eb26-11e9-b62b-52540065bddc, we see

FAIL 9A (7s)

In ~~LU-12632~~, Hongchao looked at some of sanity-hsm errors and said:

On LDiskFS
the related HSM archive operations are not started, and it could be caused by the absence of "libtool"

CMD: onyx-34vm7 libtool --mode=e pkill -x lhsmtool_posix
onyx-34vm7: sh: libtool: command not found
CMD: onyx-34vm7 rm -rf /tmp/arc1/sanity-hsm.test_90/
it cause the previous copy tool can't be killed and affect the following copy tool.

As Hongchao points out, we do see the 'libtool command missing' message in the logs for the failed test sessions.
