h3. Scheduling a suite

This requires access to a running teuthology cluster, for instance the cluster from the sepia lab.

* git clone https://github.com/ceph/teuthology/

* cd teuthology

* ./bootstrap

* Test the suite with *--dry-run*, i.e. something like:

<pre>

./virtualenv/bin/teuthology-suite --dry-run --filter-out btrfs,ext4 --priority 1000 --suite rados --suite-branch giant --machine-type plana,burnupi,mira --distro ubuntu --email loic@dachary.org --ceph giant

</pre>

* Review the jobs to be scheduled and if it matches what is expected, run the same command without the *--dry-run*

* Assuming the suite was run on the sepia lab, it will immediately show up at http://pulpito.ceph.com/ (for instance http://pulpito.ceph.com/loic-2015-03-27_09:57:09-upgrade:firefly-x:stress-split-erasure-code-hammer---basic-multi/). Note the *loic-2015-03-27_09:57:09-upgrade:firefly-x:stress-split-erasure-code-hammer---basic-multi* part of the path: it matches the run name displayed by teuthology-suite

The meaning of the teuthology-suite arguments are:

* *--suite*  a reference to https://github.com/ceph/ceph-qa-suite/tree/master/suites. For instance --suite rados means run all jobs at https://github.com/ceph/ceph-qa-suite/tree/master/suites/rados

* *--suite-branch* a reference to the ceph-qa-suite branch to use. For instance --suite rados --suite-branch giant means run all jobs at https://github.com/ceph/ceph-qa-suite/tree/giant/suites/rados instead of https://github.com/ceph/ceph-qa-suite/tree/master/suites/rados

* *--priority* is the the priority of the job in the queue (lower numbers are higher priority). By default it is 1000 and if nothing is urgent it should be used. If in the process of debugging a single job that fails, the priority 101 can be used so that it is scheduled faster.

* *--machine-type* is the kind of machine that will be provisionned to run the tests. Use *plana,burnupi,mira* for bare metal or *vps* for virtual machines.

* *--ceph* is the branch of the Ceph repository to use and defaults to master. For instance --ceph giant means use https://github.com/ceph/ceph/tree/giant/ instead of https://github.com/ceph/ceph/tree/master/

* *--email* when the run is complete an email will be sent to this address with a summary of the results.

h3. Scheduling a rados suite

In hammer "rados suite":https://github.com/ceph/ceph-qa-suite/tree/master/suites/rados generates more than 3000 jobs and it is too heavy for the purpose of validating a series of pull requests before they are merged into the stable release branch. The number of jobs can be reduced by using the *--subset* option. It will make sure every yaml (facet) is included in the run but will not include all the combinations. For instance:

<code>./virtualenv/bin/teuthology-suite --subset 1/13 --priority 101 --suite rados --suite-branch hammer --machine-type plana,burnupi,mira --distro ubuntu --email abhishek.lekshmanan@gmail.com --owner loic@dachary.org  --ceph hammer-backports</code>

Will reduce the number of jobs to *1/13* of the total number of jobs, as long as it includes all yaml (facets). 

For a given "rados suite":https://github.com/ceph/ceph-qa-suite/tree/master/suites/rados *--subset 0/13* will always create the same jobs. By running *0/13*, then *1/13*, etc. up to *13/13* all jobs are generated. It is a good idea to not always pick the same subset to get various combinations and increase the odds of discovering a problem.

h3. Re-scheduling failed or dead jobs from an existing suite

* Ask https://github.com/ceph/paddles (the server in which suite runs are stored) about the *dead* jobs

<pre>

run=loic-2015-03-23_01:09:31-rados-giant---basic-multi

eval filter=$(curl --silent http://paddles.front.sepia.ceph.com/runs/$run/jobs/?status=dead | jq '.[].description' | while read description ; do echo -n $description, ; done | sed -e 's/,$//')

</pre>

or the *fail* jobs:

<pre>

run=loic-2015-03-23_01:09:31-rados-giant---basic-multi

eval filter=$(curl --silent http://paddles.front.sepia.ceph.com/runs/$run/jobs/?status=fail | jq '.[].description' | while read description ; do echo -n $description, ; done | sed -e 's/,$//')

</pre>

* Re-run the suite using the same command line without *--filter-out* and with *--filter "$filter"* to only schedule the jobs described in the *fitler* variable

<pre>

./virtualenv/bin/teuthology-suite --filter "$filter" --priority 1000 --suite rados --suite-branch giant --machine-type plana,burnupi,mira --distro ubuntu --email loic@dachary.org --ceph giant

</pre>

h3. Killing a suite

* if the run is scheduled but did not start yet:

** if the suite was scheduled with *--machine-type plana,burnupi,mira*:

<pre>

./virtualenv/bin/teuthology-kill -m multi -r loic-2015-03-27_09:57:09-upgrade:firefly-x:stress-split-erasure-code-hammer 

</pre>

** if the suite was scheduled with *--machine-type vps*

<pre>

./virtualenv/bin/teuthology-kill -m vps -r loic-2015-03-27_09:57:09-upgrade:firefly-x:stress-split-erasure-code-hammer

</pre>

* if the run already started the *-m* option is not necessary

<pre>

./virtualenv/bin/teuthology-kill -r loic-2015-03-27_09:57:09-upgrade:firefly-x:stress-split-erasure-code-hammer

</pre>

h3. Integration suites

Expected to be successfully run on the integration branch before "asking approval to the leads":http://ceph.com/docs/master/dev/development-workflow/#resolving-bug-reports-and-implementing-features (hence before asking QE to tests further)

"rados":https://github.com/ceph/ceph-qa-suite/tree/master/suites/rados

"rgw":https://github.com/ceph/ceph-qa-suite/tree/master/suites/rgw

"rbd":https://github.com/ceph/ceph-qa-suite/tree/master/suites/rbd

"fs":https://github.com/ceph/ceph-qa-suite/tree/master/suites/fs

h3. QE suites

Expected to be successfully run on the release branch before "passing it to the person publishing the release":http://ceph.com/docs/master/dev/development-workflow/#cutting-a-new-stable-release.
