Hi Ceph,

The firefly-x test upgrade suite is designed to check that upgrading from Firefly to a newer version (master or a branch) works as expected. It was created it by copying dumpling-x and can be browsed at https://github.com/ceph/ceph-qa-suite/tree/master/suites/upgrade/firefly-x

To establish a baseline, a run was scheduled to upgrade from firefly to firefly (i.e. no upgrade really ;-) and it should therefore show that when nothing happens all is well. It however fails in various ways as can be seen here.

./virtualenv/bin/teuthology-suite --suite upgrade/firefly-x/stress-split  --suite-dir ~/software/ceph/ceph-qa-suite  --ceph firefly --machine-type vps --email loic@dachary.org http://pulpito.ceph.com/loic-2014-07-02_23:05:05-upgrade:firefly-x:stress-split-firefly-testing-basic-vps/

* Command failed on vpm105 with status 1: 'sudo yum install -y http://gitbuilder.ceph.com/kernel-rpm-redhatenterpriseserver6-x86_64-basic/sha1/8102ce7556a99f6348067c60583320d308f36362/kernel.x86_64.rpm' 
  Does that mean kernels are not ready yet for this distribution and the tests should be skipped ? 
* Command failed on vpm058 with status 1: "SWIFT_TEST_CONFIG_FILE=/home/ubuntu/cephtest/archive/testswift.client.0.conf /home/ubuntu/cephtest/swift/virtualenv/bin/nosetests -w /home/ubuntu/cephtest/swift/test/functional -v -a '!fails_on_rgw'"
  http://pulpito.ceph.com/loic-2014-07-02_23:05:05-upgrade:firefly-x:stress-split-firefly-testing-basic-vps/338941

  Although it looks like http://tracker.ceph.com/issues/7808 which is a duplicate of http://tracker.ceph.com/issues/7799 it is slightly different and http://tracker.ceph.com/issues/8735 was created to keep track of it.

* Command failed on vpm070 with status 1: 'sudo adjust-ulimits ceph-coverage /home/ubuntu/cephtest/archive/coverage daemon-helper kill ceph-osd -f -i 1'    http://pulpito.ceph.com/loic-2014-07-02_23:05:05-upgrade:firefly-x:stress-split-firefly-testing-basic-vps/338904/

   Although the root of the error seems to be that osd 1 cannot be killed by the thrasher, I don't see meaningfull error messages. http://tracker.ceph.com/issues/8736 was filed to keep track of this condition.

* timed out waiting for admin_socket to appear after osd.1 restart    http://pulpito.ceph.com/loic-2014-07-02_23:05:05-upgrade:firefly-x:stress-split-firefly-testing-basic-vps/338908/

   It looks like a race : the osd is killed at the same time it is restarted by the thrasher and http://tracker.ceph.com/issues/8737 was opened for this

* hang on "INFO:teuthology.task.rados:joining rados"
  http://pulpito.ceph.com/loic-2014-07-02_23:05:05-upgrade:firefly-x:stress-split-firefly-testing-basic-vps/338915/

  It looks like a bug and http://tracker.ceph.com/issues/8740 was filed

When the same suite is run to upgrade from firefly to master it gives http://pulpito.ceph.com/loic-2014-07-02_22:04:23-upgrade:firefly-x:stress-split-master-testing-basic-vps/ which shows the following errors:

* Command failed on vpm105 with status 1: 'sudo yum install -y http://gitbuilder.ceph.com/kernel-rpm-redhatenterpriseserver6-x86_64-basic/sha1/8102ce7556a99f6348067c60583320d308f36362/kernel.x86_64.rpm'   (same as above)

* Could not reconnect to ubuntu@vpm042.front.sepia.ceph.com  : it looks like a transient timeout problem that can be ignored
  http://pulpito.ceph.com/loic-2014-07-02_22:04:23-upgrade:firefly-x:stress-split-master-testing-basic-vps/338891/
  2014-07-02T18:52:24.546 INFO:teuthology.orchestra.connection:{'username': u'ubuntu', 'hostname': u'vpm042.front.sepia.ceph.com', 'timeout': 60}

* Command failed on vpm017 with status 1: "SWIFT_TEST_CONFIG_FILE=/home/ubuntu/cephtest/archive/testswift.client.0.conf /home/ubuntu/cephtest/swift/virtualenv/bin/nosetests -w /home/ubuntu/cephtest/swift/test/functional -v -a '!fails_on_rgw'" 
  One of which looks exactly as http://tracker.ceph.com/issues/7799 which was re-opened

* hang on "INFO:teuthology.task.rados:joining rados" (same as above)
