Testing

We use the ceph-qa-suite. First, make sure you have a sane environment by setting up the virtual environment as specified in the vstart runner (here). You need to make 2 adjustments:

1. Install packages into the Python virtual environment:

   cd /home/msevilla/teuthology
   mkdir virtualenv
   virtualenv virtualenv
   source virtualenv/bin/activate
   pip install -U setuptools manhole python-dateutil --upgrade pytz apache-libcloud
   apt-get update -y; apt-get install -y libffi-dev
   pip install gevent paramiko cryptography cffi pyaml configobj requests netaddr pexpect 
   pip install -U cffi
   

2. You should run everything as the root user (since ceph-fuse will only mount if you are the superuser) but must make one small change for this to work:

   diff --git a/tasks/cephfs/vstart_runner.py b/tasks/cephfs/vstart_runner.py
   index 3d0c7da..1fa05b9 100644
   --- a/tasks/cephfs/vstart_runner.py
   +++ b/tasks/cephfs/vstart_runner.py
   @@ -257,7 +257,7 @@ class LocalDaemon(object):
            Return PID as an integer or None if not found
            """
            ps_txt = self.controller.run(
   -            args=["ps", "-xwwu"+str(os.getuid())]
   +            args=["ps", "-xwwu1"]
            ).stdout.getvalue().strip()
            lines = ps_txt.split("\n")[1:]
   

After that you should be able to do everything from the vstart_runner.py script:

sudo su root
cd /home/msevilla/mantle/src
OSD=3 MON=1 MDS=2 ./vstart.sh -n
PYTHONPATH=/home/msevilla/teuthology/:/home/msevilla/ceph-qa-suite/ python /home/msevilla/ceph-qa-suite/tasks/cephfs/vstart_runner.py tasks.cephfs.test_mantle
PYTHONPATH=/home/msevilla/teuthology/:/ceph/qa/ python /ceph/qa/tasks/vstart_runner.py tasks.cephfs.test_mantle

I did NOT test:

• invalid balancer log

• loading lua state

• loading lua string

• Script invalid Lua or does not return array

• Script not in RADOS

• Script not set ("")
