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:

|
|
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:

|
|
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]
|
