Description
No sanity-hsm tests are run due to a problem with clients mounting the Lustre file system. Same problem for sanity-dom and racer. So far, we only see this for Ubuntu 18.04 client testing.
Looking at the client test_log for https://testing.whamcloud.com/test_sets/d791f818-fdd4-11e8-a97c-52540065bddc , we see the two clients aren’t able to mount the file system

Both clients have the following stack traces in their console logs
