This task is designed to test locking. It runs an executable
for each lock attempt you specify, at 0.01 second intervals (to
preserve ordering of the locks).
You can also introduce longer intervals by setting an entry
as a number of seconds, rather than the lock dictionary.
The config is a list of dictionaries. For each entry in the list, you
must name the "client" to run on, the "file" to lock, and
the "holdtime" to hold the lock.
Optional entries are the "offset" and "length" of the lock. You can also specify a
"maxwait" timeout period which fails if the executable takes longer
to complete, and an "expectfail".
An example::
tasks:
- ceph:
- ceph-fuse: [client.0, client.1]
- lockfile:
[{client:client.0, file:testfile, holdtime:10},
{client:client.1, file:testfile, holdtime:0, maxwait:0, expectfail:true},
{client:client.1, file:testfile, holdtime:0, maxwait:15, expectfail:false},
10,
{client: client.1, lockfile: testfile, holdtime: 5},
{client: client.2, lockfile: testfile, holdtime: 5, maxwait: 1, expectfail: True}]
In the past this test would have failed; there was a bug where waitlocks weren't
cleaned up if the process failed. More involved scenarios are also possible.

Create the specified number of pools and write 16 objects to them (thereby forcing
the PG creation on each OSD). This task creates pools from all the clients,
in parallel. It is easy to add other daemon types which have the appropriate
permissions, but I don't think anything else does.
The config is just the number of pools to create. I recommend setting
"mon create pg interval" to a very low value in your ceph config to speed
this up.
You probably want to do this to look at memory consumption, and
maybe to test how performance changes with the number of PGs. For example:
tasks:
- ceph:
config:
mon:
mon create pg interval: 1
- manypools: 3000

Set up and tear down a Ceph cluster.
For example::
tasks:

You can also specify what branch to run::
tasks:

branch: foo
Or a tag::
tasks:
- ceph:
tag: v0.42.13
Or a sha1::
tasks:
- ceph:
sha1: 1376a5ab0c89780eab39ffbbe436f6a6092314ed
Or a local source dir::
tasks:
- ceph:
path: /home/sage/ceph
To capture code coverage data, use::
tasks:
- ceph:
coverage: true
To use btrfs, ext4, or xfs on the target's scratch disks, use::
tasks:
- ceph:
fs: xfs
mkfs_options: [-b,size=65536,-l,logdev=/dev/sdc1]
mount_options: [nobarrier, inode64]
Note, this will cause the task to check the /scratch_devs file on each node
for available devices. If no such file is found, /dev/sdb will be used.
To run some daemons under valgrind, include their names
and the tool/args to use in a valgrind section::
tasks:
- ceph:
valgrind:
mds.1: --tool=memcheck
osd.1: [--tool=memcheck, --leak-check=no]
Those nodes which are using memcheck or valgrind will get
checked for bad results.
To adjust or modify config options, use::
tasks:
- ceph:
conf:
section:
key: value
For example::
tasks:
- ceph:
conf:
mds.0:
some option: value
other key: other value
client.0:
debug client: 10
debug ms: 1
By default, the cluster log is checked for errors and warnings,
and the run marked failed if any appear. You can ignore log

Set up and tear down a Ceph cluster.
For example::
tasks:
- ceph:
- interactive:
You can also specify what branch to run::
tasks:
- ceph:
branch: foo
Or a tag::
tasks:
- ceph:
tag: v0.42.13
Or a sha1::
tasks:
- ceph:
sha1: 1376a5ab0c89780eab39ffbbe436f6a6092314ed
Or a local source dir::
tasks:
- ceph:
path: /home/sage/ceph
To capture code coverage data, use::
tasks:
- ceph:
coverage: true
To use btrfs, ext4, or xfs on the target's scratch disks, use::
tasks:
- ceph:
fs: xfs
mkfs_options: [-b,size=65536,-l,logdev=/dev/sdc1]
mount_options: [nobarrier, inode64]
Note, this will cause the task to check the /scratch_devs file on each node
for available devices. If no such file is found, /dev/sdb will be used.
To run some daemons under valgrind, include their names
and the tool/args to use in a valgrind section::
tasks:
- ceph:
valgrind:
mds.1: --tool=memcheck
osd.1: [--tool=memcheck, --leak-check=no]
Those nodes which are using memcheck or valgrind will get
checked for bad results.
To adjust or modify config options, use::
tasks:
- ceph:
conf:
section:
key: value
For example::
tasks:
- ceph:
conf:
mds.0:
some option: value
other key: other value
client.0:
debug client: 10
debug ms: 1
By default, the cluster log is checked for errors and warnings,
and the run marked failed if any appear. You can ignore log
entries by giving a list of egrep compatible regexes, i.e.:
tasks:
- ceph:
log-whitelist: ['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
clusters must be on separate hosts. Clients and non-osd daemons
from multiple clusters may be colocated. For each cluster, add an
instance of the ceph task with the cluster name specified, e.g.::
roles:
- [mon.a, osd.0, osd.1]
- [backup.mon.a, backup.osd.0, backup.osd.1]
- [client.0, backup.client.0]
tasks:
- ceph:
cluster: ceph
