Bug #39651

Updated by Patrick Donnelly 12 months ago

I get following traceback while running the test_kill_mdstable: https://github.com/ceph/ceph/blob/master/qa/tasks/cephfs/test_snapshots.py#L41 test_kill_mdstable:"https://github.com/ceph/ceph/blob/master/qa/tasks/cephfs/test_snapshots.py#L41" -

CommandFailedError: Command failed with status 1: ['cd', '|/usr/lib/systemd', Raw('&&'), 'ls', Raw('|'), 'xargs', 'file']
</pre>


code_dir:"https://github.com/ceph/ceph/blob/master/qa/tasks/cephfs/cephfs_test_case.py#L257" does not contain a path to a directory at all. The value of core_dir is "|/usr/lib/systemd" which is weird because the string (which is supposed to be a path) has a vertical bar at the beginning and, more importantly, because "/usr/lib/systemd" is not a directory. The lines of code following will attempt to use it as the target directory for "cd" command. Following is the traceback obtained from running "test_kill_mdstable"
