+ceph-qa-suite
+-------------
+
+clusters/    - some predefined cluster layouts
+suites/      - set suite
+
+The suites directory has a hierarchical collection of tests.  This can be
+freeform, but generally follows the convention of
+
+  suites/<test suite name>/<test group>/...
+
+A test is described by a yaml fragment.
+
+A test can exist as a single .yaml file in the directory tree.  For example:
+
+ suites/foo/one.yaml
+ suites/foo/two.yaml
+
+is a simple group of two tests.
+
+A directory with a magic '+' file represents a test that combines all
+other items in the directory into a single yaml fragment.  For example:
+
+ suites/foo/bar/+
+ suites/foo/bar/a.yaml
+ suites/foo/bar/b.yaml
+ suites/foo/bar/c.yaml
+
+is a single test consisting of a + b + c.
+
+A directory with a magic '%' file represents a test matrix formed from
+all other items in the directory.  For example,
+
+ suites/baz/%
+ suites/baz/a.yaml
+ suites/baz/b/b1.yaml
+ suites/baz/b/b2.yaml
+ suites/baz/c.yaml
+ suites/baz/d/d1.yaml
+ suites/baz/d/d2.yaml
+
+is a 4-dimensional test matrix.  Two dimensions (a, c) are trivial (1
+item), so this is really 2x2 = 4 tests, which are
+
+  a + b1 + c + d1
+  a + b1 + c + d2
+  a + b2 + c + d1
+  a + b2 + c + d2
+
+A directory with a magic '$' file, or a directory whose name ends with '$',
+represents a test where one of the non-magic items is chosen randomly.  For
+example, both
+
+ suites/foo/$
+ suites/foo/a.yaml
+ suites/foo/b.yaml
+ suites/foo/c.yaml
+
+and
+
+ suites/foo$/a.yaml
+ suites/foo$/b.yaml
+ suites/foo$/c.yaml
+
+is a single test, either a, b or c.  This can be used in conjunction with the
+'%' file in the same (see below) or other directories to run a series of tests
+without causing an unwanted increase in the total number of jobs run.
+
+Symlinks are okay.
+
+One particular use of symlinks is to combine '%' and the latter form of '$'
+feature.  Consider supported_distros directory containing fragments that define
+os_type and os_version:
+
+ supported_distros/%
+ supported_distros/centos.yaml
+ supported_distros/rhel.yaml
+ supported_distros/ubuntu.yaml
+
+A test that links supported_distros as distros (a name that doesn't end with
+'$') will be run three times: on centos, rhel and ubuntu.  A test that links
+supported_distros as distros$ will be run just once: either on centos, rhel or
+ubuntu, chosen randomly.
+
+The teuthology code can be found in https://github.com/ceph/teuthology.git

+This directory contains scripts to quickly bring up an OpenStack instance,
+attach a ceph cluster, create a nova compute node, and store the associated glance images, cinder volumes, nova vm, and cinder backup on ceph via rbd.
+
+execs is a directory that contains executables that are copied and remotely
+run on the OpenStack instance
+
+files is a directory that contains templates used to initialize OpenStack
+conf files.  These templates reflect the state of these conf files on 5/17/2016.
+If further development is necessary in the future, these templates should
+probably be removed and direct editing of the OpenStack conf files should
+probably be performed.
+
+These scripts also assume that either there is a rhel iso file named
+rhel-server-7.2-x86_64-boot.iso in the user's home directory, or the
+exported variable RHEL_ISO is set to point at an existing rhel iso file.
+If one is also running the ceph-deploy based ceph_install.sh, this script
+also assumes that there is a file named rhceph-1.3.1-rhel-7-x86_64-dvd.iso
+in the files directory.  These iso files can be obtained from the rhel site
+and are not stored with these scripts.
+
+To install openstack:
+./openstack.sh <openstack-admin-node> <ceph-monitor-node>
+
+This assumes that the ceph cluster is already set up.
+
+To setup a ceph-cluster using an iso and ceph-deploy:
+./ceph_install.sh <admin-node> <mon-node> <osd-node> <osd-node> <osd-node>
+
+To setup a ceph-cluster using the cdn and ceph-ansible:
+cd ceph_install_w_ansible
+./ceph_install.sh <admin-node> <mon-node> <osd-node> <osd-node> <osd-node>

+ceph_install.sh installs a ceph cluster using the cdn and ceph-ansible.
+
+Right now, it takes 5 parameters -- an admin node, a ceph mon node, and
+three osd nodes.
+
+In order to subscribe to the cdn, in your home directory create a file named
+secrets, (~/secrets), that contains the following lines:
+
+subscrname=Your-Redhat-Cdn-Id
+subscrpassword=Your-Redhat-Cdn-Password
+
+If you want to set the monitor_interface or the public_network values,
+in your home directory create a file named ip_info (~/ip_info), that
+contains the following lines: 
+
+mon_intf=your-monitor-interface (default is eno1)
+pub_netw=public-network (default is 10.8.128.0/21)
+
+This script first subscribes to the cdn, enables the rhel 7 repos, and does
+a yum update.  (multi_action.sh performs all the actions on all nodes at once,
+staller.sh is used to make sure that all updates are complete before exiting,
+and execs/cdn_setup.sh is used to remotely update the cdn information.
+
+After that, it makes sure that all nodes can connect via passwordless ssh
+(using talknice.sh and config) and then installs the appropriate repos and
+runs ceph_ansible on the admin node using execs/ceph_ansible.sh,
+execs/edit_ansible_hosts.sh and execs/edit_groupvars_osds.sh.
+
+repolocs.sh contains the locations of repo files.  These variables can
+be changed if one wishes to use different urls.

+=============
+
+These scripts run standalone clusters, but not in a normal way.  They make
+use of functions ceph-helpers.sh to quickly start/stop daemons against
+toy clusters in a single directory.
+
+They are normally run via teuthology based on qa/suites/rados/standalone/*.yaml.
+
+You can run them in a git checkout + build directory as well:
+
+  * The qa/run-standalone.sh will run all of them in sequence.  This is slow
+     since there is no parallelism.
+
+  * You can run individual script(s) by specifying the basename or path below
+    qa/standalone as arguments to qa/run-standalone.sh.
+
+../qa/run-standalone.sh misc.sh osd/osd-dup.sh
+
+  * Add support for specifying arguments to selected tests by simply adding
+    list of tests to each argument.

+#  Each function is documented, implemented and tested independently.

+
+    By default, the cluster log is checked for errors and warnings,

+        - ceph:
+            log-ignorelist: ['foo.*bar', 'bad message']
+
+    To run multiple ceph clusters, use multiple ceph tasks, and roles
+    with a cluster name prefix, e.g. cluster1.client.0. Roles with no
+    cluster use the default cluster name, 'ceph'. OSDs from separate

+
+    The MDSThrasher thrashes MDSs during execution of other tasks (workunits, etc).
+
+    The config is optional.  Many of the config parameters are a a maximum value
+    to use when selecting a random value from a range.  To always use the maximum
+    value, set no_random to true.  The config is a dict containing some or all of:
+
+    max_thrash: [default: 1] the maximum number of active MDSs per FS that will be thrashed at
+      any given time.
+
+    max_thrash_delay: [default: 30] maximum number of seconds to delay before
+      thrashing again.
+
+    max_replay_thrash_delay: [default: 4] maximum number of seconds to delay while in
+      the replay state before thrashing.
+
+    max_revive_delay: [default: 10] maximum number of seconds to delay before
+      bringing back a thrashed MDS.
+
+    randomize: [default: true] enables randomization and use the max/min values
+
+    seed: [no default] seed the random number generator
+
+    thrash_in_replay: [default: 0.0] likelihood that the MDS will be thrashed
+      during replay.  Value should be between 0.0 and 1.0.
+
+    thrash_max_mds: [default: 0.05] likelihood that the max_mds of the mds
+      cluster will be modified to a value [1, current) or (current, starting
+      max_mds]. Value should be between 0.0 and 1.0.
+
+    thrash_while_stopping: [default: false] thrash an MDS while there
+      are MDS in up:stopping (because max_mds was changed and some
+      MDS were deactivated).
+
+    thrash_weights: allows specific MDSs to be thrashed more/less frequently.
+      This option overrides anything specified by max_thrash.  This option is a
+      dict containing mds.x: weight pairs.  For example, [mds.a: 0.7, mds.b:
+      0.3, mds.c: 0.0].  Each weight is a value from 0.0 to 1.0.  Any MDSs not
+      specified will be automatically given a weight of 0.0 (not thrashed).
+      For a given MDS, by default the trasher delays for up to
+      max_thrash_delay, trashes, waits for the MDS to recover, and iterates.
+      If a non-zero weight is specified for an MDS, for each iteration the
+      thrasher chooses whether to thrash during that iteration based on a
+      random value [0-1] not exceeding the weight of that MDS.
+
+    Examples::
+
+
+      The following example sets the likelihood that mds.a will be thrashed
+      to 80%, mds.b to 20%, and other MDSs will not be thrashed.  It also sets the
+      likelihood that an MDS will be thrashed in replay to 40%.
+      Thrash weights do not have to sum to 1.
+
+      tasks:
+      - ceph:
+      - mds_thrash:
+          thrash_weights:
+            - mds.a: 0.8
+            - mds.b: 0.2
+          thrash_in_replay: 0.4
+      - ceph-fuse:
+      - workunit:
+          clients:
+            all: [suites/fsx.sh]
+
+      The following example disables randomization, and uses the max delay values:
+
+      tasks:
+      - ceph:
+      - mds_thrash:
+          max_thrash_delay: 10

+
+    min_in: (default 4) the minimum number of OSDs to keep in the

+       waiting until the cluster goes clean. (In reality this is used
+       to probabilistically choose when to wait, and the method used
+       makes it closer to -- but not identical to -- the half-life.)
+
+    scrub_interval: (-1) the approximate length of time to loop before
+       waiting until a scrub is performed while cleaning. (In reality
+       this is used to probabilistically choose when to wait, and it
+       only applies to the cases where cleaning is being performed).
+       -1 is used to indicate that no scrubbing will be done.
+
+    chance_down: (0.4) the probability that the thrasher will mark an
+       OSD down rather than marking it out. (The thrasher will not
+       consider that OSD out of the cluster, since presently an OSD
+       wrongly marked down will mark itself back up again.) This value
+       can be either an integer (eg, 75) or a float probability (eg
+       0.75).

+    chance_test_min_size: (0) chance to run test_pool_min_size,
+       which:
+       - kills all but one osd
+       - waits
+       - kills that osd
+       - revives all other osds
+       - verifies that the osds fully recover
+
+    timeout: (360) the number of seconds to wait for the cluster
+       to become clean after each cluster change. If this doesn't
+       happen within the timeout, an exception will be raised.
+
+    revive_timeout: (150) number of seconds to wait for an osd asok to
+       appear after attempting to revive the osd
+
+    thrash_primary_affinity: (true) randomly adjust primary-affinity
+
+    chance_pgnum_grow: (0) chance to increase a pool's size

+    pool_grow_by: (10) amount to increase pgnum by

+
+    The strategy here is to set up a private virtual subnet that is larger than
+    the subnet the machine(s) exist in, and allocate virtual IPs from that pool.
+
+    - The teuthology.yaml must include a section like::
+
+        vip:
+          - machine_subnet: 172.21.0.0/20
+            virtual_subnet: 10.0.0.0/16
+
+      At least one item's machine_subnet should map the subnet the test machine's
+      primary IP lives in (the one DNS resolves to).  The virtual_subnet must have a
+      shorter prefix (i.e., larger than the machine_subnet).  If there are multiple
+      machine_subnets, they cannot map into the same virtual_subnet.
+
+    - Each machine gets an IP in the virtual_subset statically configured by the vip
+      task. This lets all test machines reach each other and (most importantly) any
+      virtual IPs.
+
+    - 1 or more virtual IPs are then mapped for the task.  These IPs are chosen based
+      on one of the remotes.  This uses a lot of network space but it avoids any
+      conflicts between tests.
+
+    To use a virtual IP, the {{VIP0}}, {{VIP1}}, etc. substitutions can be used.
+    
+    {{VIPSUBNET}} is the virtual_subnet address (10.0.0.0 in the example).
+
+    {{VIPPREFIXLEN}} is the virtual_subnet prefix (16 in the example.

+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
+  <ceph-repo-root>/build/bin/. If present, the first argument is replaced with
+  the path to binary file.

+/* Flot plugin for plotting textual data or categories.
+
+Copyright (c) 2007-2014 IOLA and Ole Laursen.
+Licensed under the MIT license.
+
+Consider a dataset like [["February", 34], ["March", 20], ...]. This plugin
+allows you to plot such a dataset directly.
+
+To enable it, you must specify mode: "categories" on the axis with the textual
+labels, e.g.
+
+	$.plot("#placeholder", data, { xaxis: { mode: "categories" } });
+
+By default, the labels are ordered as they are met in the data series. If you
+need a different ordering, you can specify "categories" on the axis options
+and list the categories there:
+
+	xaxis: {
+		mode: "categories",
+		categories: ["February", "March", "April"]
+	}
+
+If you need to customize the distances between the categories, you can specify
+"categories" as an object mapping labels to values
+
+	xaxis: {
+		mode: "categories",
+		categories: { "February": 1, "March": 3, "April": 4 }
+	}
+
+If you don't specify all categories, the remaining categories will be numbered
+from the max value plus 1 (with a spacing of 1 between each).
+
+Internally, the plugin works by transforming the input data through an auto-
+generated mapping where the first category becomes 0, the second 1, etc.
+Hence, a point like ["February", 34] becomes [0, 34] internally in Flot (this
+is visible in hover and click events that return numbers rather than the
+category labels). The plugin also overrides the tick generator to spit out the
+categories as ticks instead of the values.
+
+If you need to map a value back to its label, the mapping is always accessible
+as "categories" on the axis object, e.g. plot.getAxes().xaxis.categories.

+
+# The purpose of this test is to exercise paths through the rbd
+# code, making sure no bad pointer references or invalid reference
+# count operations occur in the face of concurrent activity.
+#
+# Each pass of the test creates an rbd image, maps it, and writes
+# some data into the image.  It also reads some data from all of the
+# other images that exist at the time the pass executes.  Finally,
+# the image is unmapped and removed.  The image removal completes in
+# the background.
+#
+# An iteration of the test consists of performing some number of
+# passes, initating each pass as a background job, and finally
+# sleeping for a variable delay.  The delay is initially a specified
+# value, but each iteration shortens that proportionally, such that
+# the last iteration will not delay at all.
+#
+# The result exercises concurrent creates and deletes of rbd images,
+# writes to new images, reads from both written and unwritten image
+# data (including reads concurrent with writes), and attempts to
+# unmap images being read.
+
+# Usage: concurrent [-i <iter>] [-c <count>] [-d <delay>]
+#
+# Exit status:
+#     0:  success
+#     1:  usage error
+#     2:  other runtime error
+#    99:  argument count error (programming error)
+#   100:  getopt error (internal error)

+# The purpose of this test is to validate that data read from a
+# mapped rbd image is what it's expected to be.
+#
+# By default it creates an image and fills it with some data.  It
+# then reads back the data at a series of offsets known to cover
+# various situations (such as reading the beginning, end, or the
+# entirety of an object, or doing a read that spans multiple
+# objects), and stashes the results in a set of local files.
+#
+# It also creates and maps a snapshot of the original image after
+# it's been filled, and reads back the same ranges of data from the
+# snapshot.  It then compares the data read back with what was read
+# back from the original image, verifying they match.
+#
+# Clone functionality is tested as well, in which case a clone is
+# made of the snapshot, and the same ranges of data are again read
+# and compared with the original.  In addition, a snapshot of that
+# clone is created, and a clone of *that* snapshot is put through
+# the same set of tests.  (Clone testing can be optionally skipped.)

+#!/bin/sh
+#
+# rbd_mirror_helpers.sh - shared rbd-mirror daemon helper functions
+#
+# The scripts starts two ("local" and "remote") clusters using mstart.sh script,
+# creates a temporary directory, used for cluster configs, daemon logs, admin
+# socket, temporary files, and launches rbd-mirror daemon.
+#
+# There are several env variables useful when troubleshooting a test failure:
+#
+#  RBD_MIRROR_NOCLEANUP  - if not empty, don't run the cleanup (stop processes,
+#                          destroy the clusters and remove the temp directory)
+#                          on exit, so it is possible to check the test state
+#                          after failure.
+#  RBD_MIRROR_TEMDIR     - use this path when creating the temporary directory
+#                          (should not exist) instead of running mktemp(1).
+#  RBD_MIRROR_ARGS       - use this to pass additional arguments to started
+#                          rbd-mirror daemons.
+#  RBD_MIRROR_VARGS      - use this to pass additional arguments to vstart.sh
+#                          when starting clusters.
+#  RBD_MIRROR_INSTANCES  - number of daemons to start per cluster
+#  RBD_MIRROR_CONFIG_KEY - if not empty, use config-key for remote cluster
+#                          secrets
+# The cleanup can be done as a separate step, running the script with
+# `cleanup ${RBD_MIRROR_TEMDIR}' arguments.
+#
+# Note, as other workunits tests, rbd_mirror_journal.sh expects to find ceph binaries
+# in PATH.
+#
+# Thus a typical troubleshooting session:
+#
+# From Ceph src dir (CEPH_SRC_PATH), start the test in NOCLEANUP mode and with
+# TEMPDIR pointing to a known location:
+#
+#   cd $CEPH_SRC_PATH
+#   PATH=$CEPH_SRC_PATH:$PATH
+#   RBD_MIRROR_NOCLEANUP=1 RBD_MIRROR_TEMDIR=/tmp/tmp.rbd_mirror \
+#     ../qa/workunits/rbd/rbd_mirror_journal.sh
+#
+# After the test failure cd to TEMPDIR and check the current state:
+#
+#   cd /tmp/tmp.rbd_mirror
+#   ls
+#   less rbd-mirror.cluster1_daemon.$pid.log
+#   ceph --cluster cluster1 -s
+#   ceph --cluster cluster1 -s
+#   rbd --cluster cluster2 -p mirror ls
+#   rbd --cluster cluster2 -p mirror journal status --image test
+#   ceph --admin-daemon rbd-mirror.cluster1_daemon.cluster1.$pid.asok help
+#   ...
+#
+# Also you can execute commands (functions) from the script:
+#
+#   cd $CEPH_SRC_PATH
+#   export RBD_MIRROR_TEMDIR=/tmp/tmp.rbd_mirror
+#   ../qa/workunits/rbd/rbd_mirror_journal.sh status
+#   ../qa/workunits/rbd/rbd_mirror_journal.sh stop_mirror cluster1
+#   ../qa/workunits/rbd/rbd_mirror_journal.sh start_mirror cluster2
+#   ../qa/workunits/rbd/rbd_mirror_journal.sh flush cluster2
+#   ...
+#
+# Eventually, run the cleanup:
+#
+#   cd $CEPH_SRC_PATH
+#   RBD_MIRROR_TEMDIR=/tmp/tmp.rbd_mirror \
+#     ../qa/workunits/rbd/rbd_mirror_journal.sh cleanup
