""" vstart_runner: override Filesystem and Mount interfaces to run a CephFSTestCase against a vstart ceph instance instead of a packaged/installed cluster. Use this to turn around test cases quickly during development. Simple usage (assuming teuthology and ceph checked out in ~/git): # Activate the teuthology virtualenv source ~/git/teuthology/virtualenv/bin/activate # Go into your ceph build directory cd ~/git/ceph/build # Invoke a test using this script python ~/git/ceph/qa/tasks/vstart_runner.py --create tasks.cephfs.test_data_scan Alternative usage: # Alternatively, if you use different paths, specify them as follows: LD_LIBRARY_PATH=`pwd`/lib PYTHONPATH=~/git/teuthology:~/git/ceph/qa:`pwd`/../src/pybind:`pwd`/lib/cython_modules/lib.3 python ~/git/ceph/qa/tasks/vstart_runner.py # If you wish to drop to a python shell on failures, use --interactive: python ~/git/ceph/qa/tasks/vstart_runner.py --interactive # If you wish to run a named test case, pass it as an argument: python ~/git/ceph/qa/tasks/vstart_runner.py tasks.cephfs.test_data_scan # Also, you can create the cluster once and then run named test cases against it: python ~/git/ceph/qa/tasks/vstart_runner.py --create-cluster-only python ~/git/ceph/qa/tasks/vstart_runner.py tasks.mgr.dashboard.test_health python ~/git/ceph/qa/tasks/vstart_runner.py tasks.mgr.dashboard.test_rgw Following are few important notes that might save some investigation around vstart_runner.py - * If using the FUSE client, ensure that the fuse package is installed and enabled on the system and that "user_allow_other" is added to /etc/fuse.conf. * If using the kernel client, the user must have the ability to run commands with passwordless sudo access. * A failure on the kernel client may crash the host, so it's recommended to use this functionality within a virtual machine. * "adjust-ulimits", "ceph-coverage" and "sudo" in command arguments are overridden by vstart_runner.py. Former two usually have no applicability for test runs on developer's machines and see note point on "omit_sudo" to know more about overriding of "sudo". * "omit_sudo" is re-set to False unconditionally in cases of commands "passwd" and "chown". * The presence of binary file named after the first argument in the command arguments received by the method LocalRemote.run() is checked for in /build/bin/. If present, the first argument is replaced with the path to binary file.
