Please skip this test with --skip-tags latencycheck For example: ansible-playbook -i <inventory-file> <playbook> --skip-tags latencycheck This check was added to ensure that disklatency would be tested. I have removed this check in this PR: https://github.com/gluster/gluster-ansible-features/pull/33/commits/3e52d... Will make it available once it is reviewed and merged.
