This commit introduces following two set of changes - First, make client keyring path, mountpoint on host FS and CephFS and CephFS's name attributes of the object representing the mount and update all the mount object creation calls accordingly. Also, rewrite all the mount object creation to use keyword arguments instead of positional arguments to avoid mistakes, especially since a new argument was added in this commit. Second, add remount method to mount.py so that it's possible to unmount safely, modify the attributes of the object representing the mount and mount again based on new state of the object *in a single call*. The method is placed in mount.py to avoid duplication. This change has two leads to two more changes: upgrading interface of mount() and mount_wait() and upgrading testsuites to adapt to these change. Signed-off-by: Rishabh Dave <ridave@redhat.com>

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
