No MDS is configured for this test.

  roles:
  - - mon.a
    - mon.b
    - mon.c
    - mgr.x
    - osd.0
    - osd.1
    - osd.2
    - client.0

That appears to have always been the case. Normally the workunit skips MDS related tests:

2026-01-25T12:08:02.371 INFO:tasks.workunit.client.0.trial025.stderr:/home/ubuntu/cephtest/clone.client.0/qa/workunits/cephtool/test.sh:2831: test_mds_tell_help_command:  echo 'Skipping test, no MDS found'

but this one recently added does not:

2026-01-25T12:08:02.579 INFO:tasks.workunit.client.0.trial025.stderr:/home/ubuntu/cephtest/clone.client.0/qa/workunits/cephtool/test.sh:3101: :  test_mds_messenger_dump

Cause is: 75a02c25db6a62aee6dac0f8e47686f67be0889e

I suggest just adding an MDS to this suite so you can actually exercise the Ceph commands relating to MDS.

Moving this back to RADOS for your team to decide how to proceed.
